This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address.

Superdome is represented by three models with 16, 32 and 64 processor sockets. Within the family, there is the possibility of moving from younger models to older ones, which ensures a reduction in initial costs, investment protection and the possibility of a phased increase in system performance. Superdome is a universal hierarchical crossbar architecture specifically designed to work with various types of processors. The main components of the architecture are Cells, Crossbar Backplane, and I / O subsystems.<br />\r\nThe cell board is the main unit of the Superdome system. It is a symmetrical multiprocessor (SMP) containing 4 processor sockets and up to 64 GB of main memory. It is possible (but not necessary) to connect to the cell its own I / O subsystem, which is an I / O basket with 12 PCI-X slots. Each cell can work in different configurations, i.e., be connected to other cells or form an independent independent server. In one system, cell boards can be combined with both PA-RISC processors and Itanium processors.<br />\r\nBackplane patch panels provide a non-blocking connection between cells, their associated memory, and I / O modules. The main principle underlying Superdome is the balanced performance of the system at all levels of the hierarchy in order to exclude the appearance of additional delays when the processors of one cell access the RAM located on other cells. The developed architecture allows the system to demonstrate record performance indicators for various types of tasks, such as operational transaction processing, technical calculations, processing of Internet transactions, analysis of large volumes of data, etc.<br />\r\nA single Superdome system can be logically divided into many hardware independent, software independent partitions, virtual machines, or resource partitions within a single server. Each hardware / software partition or virtual machine is running its own independent operating system. For cells with PA-RISC processors, the operating system is HP-UX 11i, and for cells with Itanium processors, HP-UX, Linux, Microsoft Windows 2003, and OpenVMS.\r\nTo implement effective system management and technical support, the Superdome server family includes:\r\n<ul><li>Event Monitoring System (EMS), an alert service that monitors the status of server hardware, including processors, memory, FC components, system buses, cache, system temperature, battery status, fans, power supplies.</li></ul>\r\n<ul><li>A hardware inventory service in Support Tools Manager (STM) that provides system inventory information, including serial numbers, part numbers, version levels, and so on.</li></ul>\r\n<ul><li>Support Management Station (SMS), which is used to start the process of scanning, diagnostics and testing the platform throughout the life cycle, including upgrades.</li></ul>\r\nThe Superdome family provides customers with investment protection and uptime thanks to a system infrastructure designed to upgrade to next-generation processors.","shortDescription":"HP Superdome is a premium server designed and manufactured by Hewlett Packard Enterprise.","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":false,"bonus":100,"usingCount":19,"sellingCount":13,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"HP Integrity Superdome","keywords":"","description":"HP Superdome is the family of enterprise-class high-performance servers manufactured with both the PA-8900 processors (HP 9000 family) and Intel Itanium 2 processors (HP Integrity family).

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse.

This is why careful creation of backup copies is so important.\r\nCreating backup copies may be burdensome and very expensive and time-consuming when you do it all by yourself.

Tier one players such as IBM, Hewlett Packard Enterprise, EMC Corporation, Symantec Corporation and Microsoft Corporation are also moving towards these technologies through partnerships and acquisitions.\r\nThe major factor driving data protection and recovery software market is the high adoption of cloud-based services and technologies. Many organizations are moving towards the cloud to reduce their operational expenses and to provide real-time access to their employees. However, increased usage of the cloud has increased the risk of data loss and data theft and unauthorized access to confidential information, which increases the demand for data protection and recovery solution suites.","materialsDescription":" \r\n<span style=\"font-weight: bold; \">What is Data recovery?</span>\r\nData recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a normal way. The data is most often salvaged from storage media such as internal or external hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, and other electronic devices. Recovery may be required due to physical damage to the storage devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).\r\nThe most common data recovery scenario involves an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive. This can be easily accomplished using a Live CD or DVD by booting directly from a ROM instead of the corrupted drive in question. Many Live CDs or DVDs provide a means to mount the system drive and backup drives or removable media, and to move the files from the system drive to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.\r\nAnother scenario involves a drive-level failure, such as a compromised file system or drive partition, or a hard disk drive failure. In any of these cases, the data is not easily read from the media devices. Depending on the situation, solutions involve repairing the logical file system, partition table or master boot record, or updating the firmware or drive recovery techniques ranging from software-based recovery of corrupted data, hardware- and software-based recovery of damaged service areas (also known as the hard disk drive's "firmware"), to hardware replacement on a physically damaged drive which allows for extraction of data to a new drive. If a drive recovery is necessary, the drive itself has typically failed permanently, and the focus is rather on a one-time recovery, salvaging whatever data can be read.\r\nIn a third scenario, files have been accidentally "deleted" from a storage medium by the users. Typically, the contents of deleted files are not removed immediately from the physical drive; instead, references to them in the directory structure are removed, and thereafter space the deleted data occupy is made available for later data overwriting. In the mind of end users, deleted files cannot be discoverable through a standard file manager, but the deleted data still technically exists on the physical drive. In the meantime, the original file contents remain, often in a number of disconnected fragments, and may be recoverable if not overwritten by other data files.\r\nThe term "data recovery" is also used in the context of forensic applications or espionage, where data which have been encrypted or hidden, rather than damaged, are recovered. Sometimes data present in the computer gets encrypted or hidden due to reasons like virus attack which can only be recovered by some computer forensic experts.\r\n<span style=\"font-weight: bold;\">What is a backup?</span>\r\nA backup, or data backup, or the process of backing up, refers to the copying into an archive file of computer data that is already in secondary storage—so that it may be used to restore the original after a data loss event. The verb form is "back up" (a phrasal verb), whereas the noun and adjective form is "backup".\r\nBackups have two distinct purposes. The primary purpose is to recover data after its loss, be it by data deletion or corruption. Data loss can be a common experience of computer users; a 2008 survey found that 66% of respondents had lost files on their home PC. The secondary purpose of backups is to recover data from an earlier time, according to a user-defined data retention policy, typically configured within a backup application for how long copies of data are required. Though backups represent a simple form of disaster recovery and should be part of any disaster recovery plan, backups by themselves should not be considered a complete disaster recovery plan. One reason for this is that not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server by simply restoring data from a backup.\r\nSince a backup system contains at least one copy of all data considered worth saving, the data storage requirements can be significant. Organizing this storage space and managing the backup process can be a complicated undertaking. A data repository model may be used to provide structure to the storage. Nowadays, there are many different types of data storage devices that are useful for making backups. There are also many different ways in which these devices can be arranged to provide geographic redundancy, data security, and portability.\r\nBefore data are sent to their storage locations, they are selected, extracted, and manipulated. Many different techniques have been developed to optimize the backup procedure. These include optimizations for dealing with open files and live data sources as well as compression, encryption, and de-duplication, among others. Every backup scheme should include dry runs that validate the reliability of the data being backed up. It is important to recognize the limitations and human factors involved in any backup scheme.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Data_Protection_and_Recovery_Software__1_.png"},{"id":509,"title":"Converged and Hyper Converged System","alias":"converged-and-hyper-converged-system","description":" Converged and hyper convergent infrastructures simplify support for virtual desktop infrastructure and desktop virtualization, as they are designed to be easy to install and perform complex tasks.\r\nConvergent infrastructure combines the four main components of a data center in one package: computing devices, storage devices, network devices, and server virtualization tools. Hyper-converged infrastructure allows for tighter integration of a larger number of components using software tools.\r\nIn both convergent and hyper-convergent infrastructure, all elements are compatible with each other. Thanks to this, you will be able to purchase the necessary storage devices and network devices for your company at a time, and they, as you know, are of great importance in the virtual desktops infrastructure. This allows you to simplify the process of deploying such an infrastructure - something that has been waiting for and what will be rejoiced by many companies that need to virtualize their desktop systems.\r\nDespite its value and innovation, there are several questions to these technologies regarding their intended use and differences. Let's try to figure out what functionality offers converged and hyper-convergent infrastructures and how they differ.","materialsDescription":" <span style=\"font-weight: bold;\">What is converged infrastructure?</span>\r\nConvergent infrastructure combines computing devices, storage, network devices and server virtualization tools in one chassis so that they can be managed from one place. Management capabilities may include the management of virtual desktop infrastructure, depending on the selected configuration and manufacturer.\r\nThe hardware included in the bundled converged infrastructure is pre-configured to support any targets: virtual desktop infrastructures, databases, special applications, and so on. But in fact, you do not have enough freedom to change the selected configuration.\r\nRegardless of the method chosen for extending the virtual desktop infrastructure environment, you should understand that subsequent vertical scaling will be costly and time-consuming. Adding individual components is becoming complex and depriving you of the many benefits of a converged infrastructure. Adding workstations and expanding storage capacity in a corporate infrastructure can be just as expensive, which suggests the need for proper planning for any virtual desktop infrastructure deployment.\r\nOn the other hand, all components of a converged infrastructure can work for a long time. For example, a complete server of such infrastructure works well even without the rest of the infrastructure components.\r\n<span style=\"font-weight: bold;\">What is a hyper-convergent infrastructure?</span>\r\nThe hyper-converged infrastructure was built on the basis of converged infrastructure and the concept of a software-defined data center. It combines all the components of the usual data center in one system. All four key components of the converged infrastructure are in place, but sometimes it also includes additional components, such as backup software, snapshot capabilities, data deduplication functionality, intermediate compression, global network optimization (WAN), and much more. Convergent infrastructure relies primarily on hardware, and software-defined data center often adapts to any hardware. In the hyper-convergent infrastructure, these two possibilities are combined.\r\nHyper-converged infrastructure is supported by one supplier. It can be managed as a single system with a single set of tools. To expand the infrastructure, you just need to install blocks of necessary devices and resources (for example, storage) into the main system block. And this is done literally on the fly.\r\nSince the hyper-convergent infrastructure is software-defined (that is, the operation of the infrastructure is logically separated from the physical equipment), the mutual integration of components is denser than in a conventional converged infrastructure, and the components themselves must be nearby to work correctly. This makes it possible to use a hyper-convergent infrastructure to support even more workloads than in the case of conventional converged infrastructure. This is explained by the fact that it has the possibility of changing the principle of definition and adjustment at the program level. In addition, you can make it work with specialized applications and workloads, which pre-configured converged infrastructures do not allow.\r\nHyper-converged infrastructure is especially valuable for working with a virtual desktop infrastructure because it allows you to scale up quickly without additional costs. Often, in the case of the classic virtual desktops infrastructure, things are completely different - companies need to buy more resources before scaling or wait for virtual desktops to use the allocated space and network resources, and then, in fact, add new infrastructure.\r\nBoth scenarios require significant time and money. But, in the case of hyperconvergent infrastructure, if you need to expand the storage, you can simply install the required devices in the existing stack. Scaling can be done quickly — for the time required to deliver the equipment. In this case, you do not have to go through the full procedure of re-evaluation and reconfiguration of the corporate infrastructure.\r\nIn addition, when moving from physical PCs to virtual workstations, you will need devices to perform all the computational tasks that laptops and PCs typically perform. Hyper-converged infrastructure will greatly help with this, as it often comes bundled with a large amount of flash memory, which has a positive effect on the performance of virtual desktops. This increases the speed of I / O operations, smoothes work under high loads, and allows you to perform scanning for viruses and other types of monitoring in the background (without distracting users).\r\nThe flexibility of the hyper-converged infrastructure makes it more scalable and cost-effective compared to the convergent infrastructure since it has the ability to add computing and storage devices as needed. The cost of the initial investment for both infrastructures is high, but in the long term, the value of the investment should pay off.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Converged_and_Hyper_Converged_System.png"},{"id":5,"title":"Security Software","alias":"security-software","description":" Computer security software or cybersecurity software is any computer program designed to enhance information security. Security software is a broad term that encompasses a suite of different types of software that deliver data and computer and network security in various forms. \r\nSecurity software can protect a computer from viruses, malware, unauthorized users and other security exploits originating from the Internet. Different types of security software include anti-virus software, firewall software, network security software, Internet security software, malware/spamware removal and protection software, cryptographic software, and more.\r\nIn end-user computing environments, anti-spam and anti-virus security software is the most common type of software used, whereas enterprise users add a firewall and intrusion detection system on top of it. \r\nSecurity soft may be focused on preventing attacks from reaching their target, on limiting the damage attacks can cause if they reach their target and on tracking the damage that has been caused so that it can be repaired. As the nature of malicious code evolves, security software also evolves.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Firewall. </span>Firewall security software prevents unauthorized users from accessing a computer or network without restricting those who are authorized. Firewalls can be implemented with hardware or software. Some computer operating systems include software firewalls in the operating system itself. For example, Microsoft Windows has a built-in firewall. Routers and servers can include firewalls. There are also dedicated hardware firewalls that have no other function other than protecting a network from unauthorized access.\r\n<span style=\"font-weight: bold; \">Antivirus.</span> Antivirus solutions work to prevent malicious code from attacking a computer by recognizing the attack before it begins. But it is also designed to stop an attack in progress that could not be prevented, and to repair damage done by the attack once the attack abates. Antivirus software is useful because it addresses security issues in cases where attacks have made it past a firewall. New computer viruses appear daily, so antivirus and security software must be continuously updated to remain effective.\r\n<span style=\"font-weight: bold; \">Antispyware.</span> While antivirus software is designed to prevent malicious software from attacking, the goal of antispyware software is to prevent unauthorized software from stealing information that is on a computer or being processed through the computer. Since spyware does not need to attempt to damage data files or the operating system, it does not trigger antivirus software into action. However, antispyware software can recognize the particular actions spyware is taking by monitoring the communications between a computer and external message recipients. When communications occur that the user has not authorized, antispyware can notify the user and block further communications.\r\n<span style=\"font-weight: bold; \">Home Computers.</span> Home computers and some small businesses usually implement security software at the desktop level - meaning on the PC itself. This category of computer security and protection, sometimes referred to as end-point security, remains resident, or continuously operating, on the desktop. Because the software is running, it uses system resources, and can slow the computer's performance. However, because it operates in real time, it can react rapidly to attacks and seek to shut them down when they occur.\r\n<span style=\"font-weight: bold; \">Network Security.</span> When several computers are all on the same network, it's more cost-effective to implement security at the network level. Antivirus software can be installed on a server and then loaded automatically to each desktop. However firewalls are usually installed on a server or purchased as an independent device that is inserted into the network where the Internet connection comes in. All of the computers inside the network communicate unimpeded, but any data going in or out of the network over the Internet is filtered trough the firewall.<br /><br /><br />","materialsDescription":"<h1 class=\"align-center\"> <span style=\"font-weight: normal; \">What is IT security software?</span></h1>\r\nIT security software provides protection to businesses’ computer or network. It serves as a defense against unauthorized access and intrusion in such a system.

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network.

For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse.

Tier one players such as IBM, Hewlett Packard Enterprise, EMC Corporation, Symantec Corporation and Microsoft Corporation are also moving towards these technologies through partnerships and acquisitions.\r\nThe major factor driving data protection and recovery software market is the high adoption of cloud-based services and technologies.

However, increased usage of the cloud has increased the risk of data loss and data theft and unauthorized access to confidential information, which increases the demand for data protection and recovery solution suites.","materialsDescription":" \r\n<span style=\"font-weight: bold; \">What is Data recovery?</span>\r\nData recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a normal way. The data is most often salvaged from storage media such as internal or external hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, and other electronic devices. Recovery may be required due to physical damage to the storage devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).\r\nThe most common data recovery scenario involves an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive. This can be easily accomplished using a Live CD or DVD by booting directly from a ROM instead of the corrupted drive in question. Many Live CDs or DVDs provide a means to mount the system drive and backup drives or removable media, and to move the files from the system drive to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.\r\nAnother scenario involves a drive-level failure, such as a compromised file system or drive partition, or a hard disk drive failure. In any of these cases, the data is not easily read from the media devices. Depending on the situation, solutions involve repairing the logical file system, partition table or master boot record, or updating the firmware or drive recovery techniques ranging from software-based recovery of corrupted data, hardware- and software-based recovery of damaged service areas (also known as the hard disk drive's "firmware"), to hardware replacement on a physically damaged drive which allows for extraction of data to a new drive. If a drive recovery is necessary, the drive itself has typically failed permanently, and the focus is rather on a one-time recovery, salvaging whatever data can be read.\r\nIn a third scenario, files have been accidentally "deleted" from a storage medium by the users. Typically, the contents of deleted files are not removed immediately from the physical drive; instead, references to them in the directory structure are removed, and thereafter space the deleted data occupy is made available for later data overwriting. In the mind of end users, deleted files cannot be discoverable through a standard file manager, but the deleted data still technically exists on the physical drive. In the meantime, the original file contents remain, often in a number of disconnected fragments, and may be recoverable if not overwritten by other data files.\r\nThe term "data recovery" is also used in the context of forensic applications or espionage, where data which have been encrypted or hidden, rather than damaged, are recovered. Sometimes data present in the computer gets encrypted or hidden due to reasons like virus attack which can only be recovered by some computer forensic experts.\r\n<span style=\"font-weight: bold;\">What is a backup?</span>\r\nA backup, or data backup, or the process of backing up, refers to the copying into an archive file of computer data that is already in secondary storage—so that it may be used to restore the original after a data loss event. The verb form is "back up" (a phrasal verb), whereas the noun and adjective form is "backup".\r\nBackups have two distinct purposes. The primary purpose is to recover data after its loss, be it by data deletion or corruption. Data loss can be a common experience of computer users; a 2008 survey found that 66% of respondents had lost files on their home PC. The secondary purpose of backups is to recover data from an earlier time, according to a user-defined data retention policy, typically configured within a backup application for how long copies of data are required. Though backups represent a simple form of disaster recovery and should be part of any disaster recovery plan, backups by themselves should not be considered a complete disaster recovery plan. One reason for this is that not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server by simply restoring data from a backup.\r\nSince a backup system contains at least one copy of all data considered worth saving, the data storage requirements can be significant. Organizing this storage space and managing the backup process can be a complicated undertaking. A data repository model may be used to provide structure to the storage. Nowadays, there are many different types of data storage devices that are useful for making backups. There are also many different ways in which these devices can be arranged to provide geographic redundancy, data security, and portability.\r\nBefore data are sent to their storage locations, they are selected, extracted, and manipulated. Many different techniques have been developed to optimize the backup procedure. These include optimizations for dealing with open files and live data sources as well as compression, encryption, and de-duplication, among others. Every backup scheme should include dry runs that validate the reliability of the data being backed up. It is important to recognize the limitations and human factors involved in any backup scheme.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Data_Protection_and_Recovery_Software__1_.png"},{"id":509,"title":"Converged and Hyper Converged System","alias":"converged-and-hyper-converged-system","description":" Converged and hyper convergent infrastructures simplify support for virtual desktop infrastructure and desktop virtualization, as they are designed to be easy to install and perform complex tasks.\r\nConvergent infrastructure combines the four main components of a data center in one package: computing devices, storage devices, network devices, and server virtualization tools. Hyper-converged infrastructure allows for tighter integration of a larger number of components using software tools.\r\nIn both convergent and hyper-convergent infrastructure, all elements are compatible with each other. Thanks to this, you will be able to purchase the necessary storage devices and network devices for your company at a time, and they, as you know, are of great importance in the virtual desktops infrastructure. This allows you to simplify the process of deploying such an infrastructure - something that has been waiting for and what will be rejoiced by many companies that need to virtualize their desktop systems.\r\nDespite its value and innovation, there are several questions to these technologies regarding their intended use and differences. Let's try to figure out what functionality offers converged and hyper-convergent infrastructures and how they differ.","materialsDescription":" <span style=\"font-weight: bold;\">What is converged infrastructure?</span>\r\nConvergent infrastructure combines computing devices, storage, network devices and server virtualization tools in one chassis so that they can be managed from one place. Management capabilities may include the management of virtual desktop infrastructure, depending on the selected configuration and manufacturer.\r\nThe hardware included in the bundled converged infrastructure is pre-configured to support any targets: virtual desktop infrastructures, databases, special applications, and so on. But in fact, you do not have enough freedom to change the selected configuration.\r\nRegardless of the method chosen for extending the virtual desktop infrastructure environment, you should understand that subsequent vertical scaling will be costly and time-consuming. Adding individual components is becoming complex and depriving you of the many benefits of a converged infrastructure. Adding workstations and expanding storage capacity in a corporate infrastructure can be just as expensive, which suggests the need for proper planning for any virtual desktop infrastructure deployment.\r\nOn the other hand, all components of a converged infrastructure can work for a long time. For example, a complete server of such infrastructure works well even without the rest of the infrastructure components.\r\n<span style=\"font-weight: bold;\">What is a hyper-convergent infrastructure?</span>\r\nThe hyper-converged infrastructure was built on the basis of converged infrastructure and the concept of a software-defined data center. It combines all the components of the usual data center in one system. All four key components of the converged infrastructure are in place, but sometimes it also includes additional components, such as backup software, snapshot capabilities, data deduplication functionality, intermediate compression, global network optimization (WAN), and much more. Convergent infrastructure relies primarily on hardware, and software-defined data center often adapts to any hardware. In the hyper-convergent infrastructure, these two possibilities are combined.\r\nHyper-converged infrastructure is supported by one supplier. It can be managed as a single system with a single set of tools. To expand the infrastructure, you just need to install blocks of necessary devices and resources (for example, storage) into the main system block. And this is done literally on the fly.\r\nSince the hyper-convergent infrastructure is software-defined (that is, the operation of the infrastructure is logically separated from the physical equipment), the mutual integration of components is denser than in a conventional converged infrastructure, and the components themselves must be nearby to work correctly. This makes it possible to use a hyper-convergent infrastructure to support even more workloads than in the case of conventional converged infrastructure. This is explained by the fact that it has the possibility of changing the principle of definition and adjustment at the program level. In addition, you can make it work with specialized applications and workloads, which pre-configured converged infrastructures do not allow.\r\nHyper-converged infrastructure is especially valuable for working with a virtual desktop infrastructure because it allows you to scale up quickly without additional costs. Often, in the case of the classic virtual desktops infrastructure, things are completely different - companies need to buy more resources before scaling or wait for virtual desktops to use the allocated space and network resources, and then, in fact, add new infrastructure.\r\nBoth scenarios require significant time and money. But, in the case of hyperconvergent infrastructure, if you need to expand the storage, you can simply install the required devices in the existing stack. Scaling can be done quickly — for the time required to deliver the equipment. In this case, you do not have to go through the full procedure of re-evaluation and reconfiguration of the corporate infrastructure.\r\nIn addition, when moving from physical PCs to virtual workstations, you will need devices to perform all the computational tasks that laptops and PCs typically perform. Hyper-converged infrastructure will greatly help with this, as it often comes bundled with a large amount of flash memory, which has a positive effect on the performance of virtual desktops. This increases the speed of I / O operations, smoothes work under high loads, and allows you to perform scanning for viruses and other types of monitoring in the background (without distracting users).\r\nThe flexibility of the hyper-converged infrastructure makes it more scalable and cost-effective compared to the convergent infrastructure since it has the ability to add computing and storage devices as needed. The cost of the initial investment for both infrastructures is high, but in the long term, the value of the investment should pay off.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Converged_and_Hyper_Converged_System.png"},{"id":35,"title":"Server","alias":"server","description":"In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar.

A data center must therefore keep high standards for assuring the integrity and functionality of its hosted computer environment.\r\nIndustry research company International Data Corporation (IDC) puts the average age of a data center at nine years old. Gartner, another research company, says data centers older than seven years are obsolete. The growth in data (163 zettabytes by 2025) is one factor driving the need for data centers to modernize.\r\nFocus on modernization is not new: Concern about obsolete equipment was decried in 2007, and in 2011 Uptime Institute was concerned about the age of the equipment therein. By 2018 concern had shifted once again, this time to the age of the staff: "data center staff are aging faster than the equipment."\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Meeting standards for data centers</span></span>\r\nThe Telecommunications Industry Association's Telecommunications Infrastructure Standard for Data Centers specifies the minimum requirements for telecommunications infrastructure of data centers and computer rooms including single tenant enterprise data centers and multi-tenant Internet hosting data centers. The topology proposed in this document is intended to be applicable to any size data center.\r\nTelcordia GR-3160, NEBS Requirements for Telecommunications Data Center Equipment and Spaces, provides guidelines for data center spaces within telecommunications networks, and environmental requirements for the equipment intended for installation in those spaces. These criteria were developed jointly by Telcordia and industry representatives. They may be applied to data center spaces housing data processing or Information Technology (IT) equipment. The equipment may be used to:\r\n<ul><li>Operate and manage a carrier's telecommunication network</li><li>Provide data center based applications directly to the carrier's customers</li><li>Provide hosted applications for a third party to provide services to their customers</li><li>Provide a combination of these and similar data center applications</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Data center transformation</span></span>\r\nData center transformation takes a step-by-step approach through integrated projects carried out over time. This differs from a traditional method of data center upgrades that takes a serial and siloed approach. The typical projects within a data center transformation initiative include standardization/consolidation, virtualization, automation and security.\r\n<ul><li>Standardization/consolidation: Reducing the number of data centers and avoiding server sprawl (both physical and virtual) often includes replacing aging data center equipment, and is aided by standardization.</li><li>Virtualization: Lowers capital and operational expenses, reduce energy consumption. Virtualized desktops can be hosted in data centers and rented out on a subscription basis. Investment bank Lazard Capital Markets estimated in 2008 that 48 percent of enterprise operations will be virtualized by 2012. Gartner views virtualization as a catalyst for modernization.</li><li>Automating: Automating tasks such as provisioning, configuration, patching, release management and compliance is needed, not just when facing fewer skilled IT workers.</li><li>Securing: Protection of virtual systems is integrated with existing security of physical infrastructures.</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Machine room</span></span>\r\nThe term "Machine Room" is at times used to refer to the large room within a Data Center where the actual Central Processing Unit is located; this may be separate from where high-speed printers are located. Air conditioning is most important in the machine room.\r\nAside from air-conditioning, there must be monitoring equipment, one type of which is to detect water prior to flood-level situations. One company, for several decades, has had share-of-mind: Water Alert. The company, as of 2018, has 2 competing manufacturers (Invetex, Hydro-Temp) and 3 competing distributors (Longden,Northeast Flooring, Slayton).

By contrast, software is instructions that can be stored and run by hardware. Hardware is so-termed because it is "hard" or rigid with respect to changes or modifications; whereas software is "soft" because it is easy to update or change. Intermediate between software and hardware is "firmware", which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface. The progression from levels of "hardness" to "softness" in computer systems parallels a progression of layers of abstraction in computing.\r\nHardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware components.\r\nThe template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms. The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.","materialsDescription":" <span style=\"font-weight: bold; \">What does Hardware (H/W) mean?</span>\r\nHardware (H/W), in the context of technology, refers to the physical elements that make up a computer or electronic system and everything else involved that is physically tangible. This includes the monitor, hard drive, memory and CPU. Hardware works hand-in-hand with firmware and software to make a computer function.\r\n<span style=\"font-weight: bold; \">What are the types of computer systems?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Personal computer</span></span>\r\nThe personal computer, also known as the PC, is one of the most common types of computer due to its versatility and relatively low price. Laptops are generally very similar, although they may use lower-power or reduced size components, thus lower performance.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Case</span></span>\r\nThe computer case encloses and holds most of the components of the system. It provides mechanical support and protection for internal elements such as the motherboard, disk drives, and power supplies, and controls and directs the flow of cooling air over internal components. The case is also part of the system to control electromagnetic interference radiated by the computer, and protects internal parts from electrostatic discharge. Large tower cases provide extra internal space for multiple disk drives or other peripherals and usually stand on the floor, while desktop cases provide less expansion room. All-in-one style designs include a video display built into the same case. Portable and laptop computers require cases that provide impact protection for the unit. A current development in laptop computers is a detachable keyboard, which allows the system to be configured as a touch-screen tablet. Hobbyists may decorate the cases with colored lights, paint, or other features, in an activity called case modding.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power supply</span></span>\r\nA power supply unit (PSU) converts alternating current (AC) electric power to low-voltage direct current (DC) power for the internal components of the computer. Laptops are capable of running from a built-in battery, normally for a period of hours. The PSU typically uses a switched-mode power supply (SMPS), with power MOSFETs (power metal–oxide–semiconductor field-effect transistors) used in the converters and regulator circuits of the SMPS.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Motherboard</span></span>\r\nThe motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. The integrated circuit (IC) chips in a computer typically contain billions of tiny metal–oxide–semiconductor field-effect transistors (MOSFETs).\r\nComponents directly attached to or to part of the motherboard include:\r\n<ul><li><span style=\"font-weight: bold; \">The CPU (central processing unit)</span>, which performs most of the calculations which enable a computer to function, and is referred to as the brain of the computer which get a hold of program instruction from random-access memory (RAM), interprets and processes it and then send it backs to computer result so that the relevant components can carry out the instructions. The CPU is a microprocessor, which is fabricated on a metal–oxide–semiconductor (MOS) integrated circuit (IC) chip. It is usually cooled by a heat sink and fan, or water-cooling system. Most newer CPU include an on-die graphics processing unit (GPU). The clock speed of CPU governs how fast it executes instructions, and is measured in GHz; typical values lie between 1 GHz and 5 GHz. Many modern computers have the option to overclock the CPU which enhances performance at the expense of greater thermal output and thus a need for improved cooling.</li><li><span style=\"font-weight: bold; \">The chipset</span>, which includes the north bridge, mediates communication between the CPU and the other components of the system, including main memory; as well as south bridge, which is connected to the north bridge, and supports auxiliary interfaces and buses; and, finally, a Super I/O chip, connected through the south bridge, which supports the slowest and most legacy components like serial ports, hardware monitoring and fan control.</li><li><span style=\"font-weight: bold; \">Random-access memory (RAM)</span>, which stores the code and data that are being actively accessed by the CPU. For example, when a web browser is opened on the computer it takes up memory; this is stored in the RAM until the web browser is closed. It is typically a type of dynamic RAM (DRAM), such as synchronous DRAM (SDRAM), where MOS memory chips store data on memory cells consisting of MOSFETs and MOS capacitors. RAM usually comes on dual in-line memory modules (DIMMs) in the sizes of 2GB, 4GB, and 8GB, but can be much larger.</li><li><span style=\"font-weight: bold; \">Read-only memory (ROM)</span>, which stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or "booting" or "booting up". The ROM is typically a nonvolatile BIOS memory chip, which stores data on floating-gate MOSFET memory cells.</li><li><span style=\"font-weight: bold; \">The BIOS (Basic Input Output System)</span> includes boot firmware and power management firmware. Newer motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS.</li><li><span style=\"font-weight: bold; \">Buses</span> that connect the CPU to various internal components and to expand cards for graphics and sound.</li><li><span style=\"font-weight: bold; \">The CMOS</span> (complementary MOS) battery, which powers the CMOS memory for date and time in the BIOS chip. This battery is generally a watch battery.</li><li><span style=\"font-weight: bold; \">The video card</span> (also known as the graphics card), which processes computer graphics. More powerful graphics cards are better suited to handle strenuous tasks, such as playing intensive video games or running computer graphics software. A video card contains a graphics processing unit (GPU) and video memory (typically a type of SDRAM), both fabricated on MOS integrated circuit (MOS IC) chips.</li><li><span style=\"font-weight: bold; \">Power MOSFETs</span> make up the voltage regulator module (VRM), which controls how much voltage other hardware components receive.</li></ul>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Expansion cards</span></span>\r\nAn expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansion cards can be used to obtain or expand on features not offered by the motherboard.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Storage devices</span></span>\r\nA storage device is any computing hardware and digital media that is used for storing, porting and extracting data files and objects. It can hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device. Data storage is a core function and fundamental component of computers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Fixed media</span></span>\r\nData is stored by a computer using a variety of media. Hard disk drives (HDDs) are found in virtually all older computers, due to their high capacity and low cost, but solid-state drives (SSDs) are faster and more power efficient, although currently more expensive than hard drives in terms of dollar per gigabyte, so are often found in personal computers built post-2007. SSDs use flash memory, which stores data on MOS memory chips consisting of floating-gate MOSFET memory cells. Some systems may use a disk array controller for greater performance or reliability.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Removable media</span></span>\r\nTo transfer data between computers, an external flash memory device (such as a memory card or USB flash drive) or optical disc (such as a CD-ROM, DVD-ROM or BD-ROM) may be used. Their usefulness depends on being readable by other systems; the majority of machines have an optical disk drive (ODD), and virtually all have at least one Universal Serial Bus (USB) port.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input and output peripherals</span></span>\r\nInput and output devices are typically housed externally to the main computer chassis. The following are either standard or very common to many computer systems.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input</span></span>\r\nInput devices allow the user to enter information into the system, or control its operation. Most personal computers have a mouse and keyboard, but laptop systems typically use a touchpad instead of a mouse. Other input devices include webcams, microphones, joysticks, and image scanners.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Output device</span></span>\r\nOutput devices display information in a human readable form. Such devices could include printers, speakers, monitors or a Braille embosser.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Mainframe computer</span></span>\r\nA mainframe computer is a much larger computer that typically fills a room and may cost many hundreds or thousands of times as much as a personal computer. They are designed to perform large numbers of calculations for governments and large enterprises.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Departmental computing</span></span>\r\nIn the 1960s and 1970s, more and more departments started to use cheaper and dedicated systems for specific purposes like process control and laboratory automation.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Supercomputer</span></span>\r\nA supercomputer is superficially similar to a mainframe, but is instead intended for extremely demanding computational tasks. As of June 2018, the fastest supercomputer on the TOP500supercomputer list is the Summit, in the United States, with a LINPACK benchmarkscore of 122.3 PFLOPS Light, by around 29 PFLOPS.\r\nThe term supercomputer does not refer to a specific technology. Rather it indicates the fastest computations available at any given time. In mid 2011, the fastest supercomputers boasted speeds exceeding one petaflop, or 1 quadrillion (10^15 or 1,000 trillion) floating point operations per second. Supercomputers are fast but extremely costly, so they are generally used by large organizations to execute computationally demanding tasks involving large data sets. Supercomputers typically run military and scientific applications. Although costly, they are also being used for commercial applications where huge amounts of data must be analyzed. For example, large banks employ supercomputers to calculate the risks and returns of various investment strategies, and healthcare organizations use them to analyze giant databases of patient data to determine optimal treatments for various diseases and problems incurring to the country.

Wireless networking has become increasingly popular, especially for portable and handheld devices.\r\nOther networking hardware used in computers includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery.\r\nTaking a wider view, mobile phones, tablet computers and devices associated with the internet of things may also be considered networking hardware. As technology advances and IP-based networks are integrated into building infrastructure and household utilities, network hardware will become an ambiguous term owing to the vastly increasing number of network capable endpoints.","materialsDescription":" <span style=\"font-weight: bold;\">What is network equipment?</span>\r\nNetwork equipment - devices necessary for the operation of a computer network, for example: a router, switch, hub, patch panel, etc. You can distinguish between active and passive network equipment.\r\n<span style=\"font-weight: bold;\">What is an active network equipment?</span>\r\nActive networking equipment is equipment followed by some “smart” feature.

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":4772,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Dell_EMC_PowerEdge_MX_IO_Modules.jpg","logo":true,"scheme":false,"title":"Dell EMC PowerEdge MX I/O Modules","vendorVerified":0,"rating":"0.00","implementationsCount":1,"suppliersCount":0,"supplierPartnersCount":59,"alias":"dell-emc-poweredge-mx-io-modules","companyTitle":"Dell EMC","companyTypes":["vendor"],"companyId":955,"companyAlias":"dell-emc","description":"<span style=\"font-weight: bold;\">SmartFabric Services</span>\r\nRobust yet simple fabric automation that goes beyond the ordinary\r\n<ul><li>Plug and Play fabric deployment with simplified I/O Aggregation providing a single pane of glass view</li><li>Physical topology validation and compliance checking</li><li>Automated per-VLAN Quality of Service assignment based on traffic types</li><li>Self-healing fabric detects misconfigurations and link failure conditions and adjusts where possible</li></ul>\r\n<span style=\"font-weight: bold;\">Scalable fabric architecture</span>\r\nMulti-chassis scalable fabric architecture that can grow with your specific needs\r\n<ul><li>Fabric expansion capability using 25GbE connectivity across multiple chassis</li><li>Single networking domain across the fabric providing a single pane of glass view</li><li>SmartFabric Services provides a robust fabric-level automation framework</li></ul>\r\n<span style=\"font-weight: bold;\">The power of open choice</span>\r\nAn array of hardware platforms, operating systems and management services\r\n<ul><li>Choice of unique Open Networking modular switches</li><li>Choice of Dell EMC OS10 or select 3rd party OS’s</li><li>Choice of leveraging standards-based open automation tools</li></ul>\r\n<span style=\"font-weight: bold;\">Highest performance connectivity</span>\r\nOptimum connectivity to servers and storage platforms in the chassis for demanding workloads\r\n<ul><li>High-performance 25GbE and 32G FC connectivity within the chassis</li><li>High throughput and low latency performance throughout the chassis</li><li>Multi-rate 100GbE uplinks to data center leaf/spine fabric</li></ul>","shortDescription":"Maximize the demanding connectivity needs of today’s data center workloads while also lowering overall costs and network management complexity.","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":false,"bonus":100,"usingCount":5,"sellingCount":18,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"Dell EMC PowerEdge MX I/O Modules","keywords":"","description":"<span style=\"font-weight: bold;\">SmartFabric Services</span>\r\nRobust yet simple fabric automation that goes beyond the ordinary\r\n<ul><li>Plug and Play fabric deployment with simplified I/O Aggregation providing a single pane of glass view</li><li>Physical topo","og:title":"Dell EMC PowerEdge MX I/O Modules","og:description":"<span style=\"font-weight: bold;\">SmartFabric Services</span>\r\nRobust yet simple fabric automation that goes beyond the ordinary\r\n<ul><li>Plug and Play fabric deployment with simplified I/O Aggregation providing a single pane of glass view</li><li>Physical topo","og:image":"https://old.roi4cio.com/fileadmin/user_upload/Dell_EMC_PowerEdge_MX_IO_Modules.jpg"},"eventUrl":"","translationId":4773,"dealDetails":null,"roi":null,"price":null,"bonusForReference":null,"templateData":[],"testingArea":"","categories":[{"id":35,"title":"Server","alias":"server","description":"In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".

In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png"},{"id":471,"title":"Hardware","alias":"hardware","description":" Computer hardware includes the physical, tangible parts or components of a computer, such as the cabinet, central processing unit, monitor, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is instructions that can be stored and run by hardware. Hardware is so-termed because it is "hard" or rigid with respect to changes or modifications; whereas software is "soft" because it is easy to update or change. Intermediate between software and hardware is "firmware", which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface. The progression from levels of "hardness" to "softness" in computer systems parallels a progression of layers of abstraction in computing.\r\nHardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware components.\r\nThe template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms. The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.","materialsDescription":" <span style=\"font-weight: bold; \">What does Hardware (H/W) mean?</span>\r\nHardware (H/W), in the context of technology, refers to the physical elements that make up a computer or electronic system and everything else involved that is physically tangible. This includes the monitor, hard drive, memory and CPU. Hardware works hand-in-hand with firmware and software to make a computer function.\r\n<span style=\"font-weight: bold; \">What are the types of computer systems?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Personal computer</span></span>\r\nThe personal computer, also known as the PC, is one of the most common types of computer due to its versatility and relatively low price. Laptops are generally very similar, although they may use lower-power or reduced size components, thus lower performance.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Case</span></span>\r\nThe computer case encloses and holds most of the components of the system. It provides mechanical support and protection for internal elements such as the motherboard, disk drives, and power supplies, and controls and directs the flow of cooling air over internal components. The case is also part of the system to control electromagnetic interference radiated by the computer, and protects internal parts from electrostatic discharge. Large tower cases provide extra internal space for multiple disk drives or other peripherals and usually stand on the floor, while desktop cases provide less expansion room. All-in-one style designs include a video display built into the same case. Portable and laptop computers require cases that provide impact protection for the unit. A current development in laptop computers is a detachable keyboard, which allows the system to be configured as a touch-screen tablet. Hobbyists may decorate the cases with colored lights, paint, or other features, in an activity called case modding.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power supply</span></span>\r\nA power supply unit (PSU) converts alternating current (AC) electric power to low-voltage direct current (DC) power for the internal components of the computer. Laptops are capable of running from a built-in battery, normally for a period of hours. The PSU typically uses a switched-mode power supply (SMPS), with power MOSFETs (power metal–oxide–semiconductor field-effect transistors) used in the converters and regulator circuits of the SMPS.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Motherboard</span></span>\r\nThe motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. The integrated circuit (IC) chips in a computer typically contain billions of tiny metal–oxide–semiconductor field-effect transistors (MOSFETs).\r\nComponents directly attached to or to part of the motherboard include:\r\n<ul><li><span style=\"font-weight: bold; \">The CPU (central processing unit)</span>, which performs most of the calculations which enable a computer to function, and is referred to as the brain of the computer which get a hold of program instruction from random-access memory (RAM), interprets and processes it and then send it backs to computer result so that the relevant components can carry out the instructions. The CPU is a microprocessor, which is fabricated on a metal–oxide–semiconductor (MOS) integrated circuit (IC) chip. It is usually cooled by a heat sink and fan, or water-cooling system. Most newer CPU include an on-die graphics processing unit (GPU). The clock speed of CPU governs how fast it executes instructions, and is measured in GHz; typical values lie between 1 GHz and 5 GHz. Many modern computers have the option to overclock the CPU which enhances performance at the expense of greater thermal output and thus a need for improved cooling.</li><li><span style=\"font-weight: bold; \">The chipset</span>, which includes the north bridge, mediates communication between the CPU and the other components of the system, including main memory; as well as south bridge, which is connected to the north bridge, and supports auxiliary interfaces and buses; and, finally, a Super I/O chip, connected through the south bridge, which supports the slowest and most legacy components like serial ports, hardware monitoring and fan control.</li><li><span style=\"font-weight: bold; \">Random-access memory (RAM)</span>, which stores the code and data that are being actively accessed by the CPU. For example, when a web browser is opened on the computer it takes up memory; this is stored in the RAM until the web browser is closed. It is typically a type of dynamic RAM (DRAM), such as synchronous DRAM (SDRAM), where MOS memory chips store data on memory cells consisting of MOSFETs and MOS capacitors. RAM usually comes on dual in-line memory modules (DIMMs) in the sizes of 2GB, 4GB, and 8GB, but can be much larger.</li><li><span style=\"font-weight: bold; \">Read-only memory (ROM)</span>, which stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or "booting" or "booting up". The ROM is typically a nonvolatile BIOS memory chip, which stores data on floating-gate MOSFET memory cells.</li><li><span style=\"font-weight: bold; \">The BIOS (Basic Input Output System)</span> includes boot firmware and power management firmware. Newer motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS.</li><li><span style=\"font-weight: bold; \">Buses</span> that connect the CPU to various internal components and to expand cards for graphics and sound.</li><li><span style=\"font-weight: bold; \">The CMOS</span> (complementary MOS) battery, which powers the CMOS memory for date and time in the BIOS chip. This battery is generally a watch battery.</li><li><span style=\"font-weight: bold; \">The video card</span> (also known as the graphics card), which processes computer graphics. More powerful graphics cards are better suited to handle strenuous tasks, such as playing intensive video games or running computer graphics software. A video card contains a graphics processing unit (GPU) and video memory (typically a type of SDRAM), both fabricated on MOS integrated circuit (MOS IC) chips.</li><li><span style=\"font-weight: bold; \">Power MOSFETs</span> make up the voltage regulator module (VRM), which controls how much voltage other hardware components receive.</li></ul>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Expansion cards</span></span>\r\nAn expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansion cards can be used to obtain or expand on features not offered by the motherboard.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Storage devices</span></span>\r\nA storage device is any computing hardware and digital media that is used for storing, porting and extracting data files and objects. It can hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device. Data storage is a core function and fundamental component of computers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Fixed media</span></span>\r\nData is stored by a computer using a variety of media. Hard disk drives (HDDs) are found in virtually all older computers, due to their high capacity and low cost, but solid-state drives (SSDs) are faster and more power efficient, although currently more expensive than hard drives in terms of dollar per gigabyte, so are often found in personal computers built post-2007. SSDs use flash memory, which stores data on MOS memory chips consisting of floating-gate MOSFET memory cells. Some systems may use a disk array controller for greater performance or reliability.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Removable media</span></span>\r\nTo transfer data between computers, an external flash memory device (such as a memory card or USB flash drive) or optical disc (such as a CD-ROM, DVD-ROM or BD-ROM) may be used. Their usefulness depends on being readable by other systems; the majority of machines have an optical disk drive (ODD), and virtually all have at least one Universal Serial Bus (USB) port.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input and output peripherals</span></span>\r\nInput and output devices are typically housed externally to the main computer chassis. The following are either standard or very common to many computer systems.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input</span></span>\r\nInput devices allow the user to enter information into the system, or control its operation. Most personal computers have a mouse and keyboard, but laptop systems typically use a touchpad instead of a mouse. Other input devices include webcams, microphones, joysticks, and image scanners.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Output device</span></span>\r\nOutput devices display information in a human readable form. Such devices could include printers, speakers, monitors or a Braille embosser.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Mainframe computer</span></span>\r\nA mainframe computer is a much larger computer that typically fills a room and may cost many hundreds or thousands of times as much as a personal computer. They are designed to perform large numbers of calculations for governments and large enterprises.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Departmental computing</span></span>\r\nIn the 1960s and 1970s, more and more departments started to use cheaper and dedicated systems for specific purposes like process control and laboratory automation.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Supercomputer</span></span>\r\nA supercomputer is superficially similar to a mainframe, but is instead intended for extremely demanding computational tasks. As of June 2018, the fastest supercomputer on the TOP500supercomputer list is the Summit, in the United States, with a LINPACK benchmarkscore of 122.3 PFLOPS Light, by around 29 PFLOPS.\r\nThe term supercomputer does not refer to a specific technology. Rather it indicates the fastest computations available at any given time. In mid 2011, the fastest supercomputers boasted speeds exceeding one petaflop, or 1 quadrillion (10^15 or 1,000 trillion) floating point operations per second. Supercomputers are fast but extremely costly, so they are generally used by large organizations to execute computationally demanding tasks involving large data sets. Supercomputers typically run military and scientific applications. Although costly, they are also being used for commercial applications where huge amounts of data must be analyzed. For example, large banks employ supercomputers to calculate the risks and returns of various investment strategies, and healthcare organizations use them to analyze giant databases of patient data to determine optimal treatments for various diseases and problems incurring to the country.

A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.\r\nData centers are not a single thing, but rather, a conglomeration of elements. At a minimum, data centers serve as the principal repositories for all manner of IT equipment, including servers, storage subsystems, networking switches, routers and firewalls, as well as the cabling and physical racks used to organize and interconnect the IT equipment. A data center must also contain an adequate infrastructure, such as power distribution and supplemental power subsystems, including electrical switching; uninterruptable power supplies; backup generators and so on; ventilation and data center cooling systems, such as computer room air conditioners; and adequate provisioning for network carrier (telco) connectivity. All of this demands a physical facility with physical security and sufficient physical space to house the entire collection of infrastructure and equipment.","materialsDescription":" <span style=\"font-weight: bold;\">What are the requirements for modern data centers?</span>\r\nModernization and data center transformation enhances performance and energy efficiency.\r\nInformation security is also a concern, and for this reason a data center has to offer a secure environment which minimizes the chances of a security breach. A data center must therefore keep high standards for assuring the integrity and functionality of its hosted computer environment.\r\nIndustry research company International Data Corporation (IDC) puts the average age of a data center at nine years old. Gartner, another research company, says data centers older than seven years are obsolete. The growth in data (163 zettabytes by 2025) is one factor driving the need for data centers to modernize.\r\nFocus on modernization is not new: Concern about obsolete equipment was decried in 2007, and in 2011 Uptime Institute was concerned about the age of the equipment therein. By 2018 concern had shifted once again, this time to the age of the staff: "data center staff are aging faster than the equipment."\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Meeting standards for data centers</span></span>\r\nThe Telecommunications Industry Association's Telecommunications Infrastructure Standard for Data Centers specifies the minimum requirements for telecommunications infrastructure of data centers and computer rooms including single tenant enterprise data centers and multi-tenant Internet hosting data centers. The topology proposed in this document is intended to be applicable to any size data center.\r\nTelcordia GR-3160, NEBS Requirements for Telecommunications Data Center Equipment and Spaces, provides guidelines for data center spaces within telecommunications networks, and environmental requirements for the equipment intended for installation in those spaces. These criteria were developed jointly by Telcordia and industry representatives. They may be applied to data center spaces housing data processing or Information Technology (IT) equipment. The equipment may be used to:\r\n<ul><li>Operate and manage a carrier's telecommunication network</li><li>Provide data center based applications directly to the carrier's customers</li><li>Provide hosted applications for a third party to provide services to their customers</li><li>Provide a combination of these and similar data center applications</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Data center transformation</span></span>\r\nData center transformation takes a step-by-step approach through integrated projects carried out over time. This differs from a traditional method of data center upgrades that takes a serial and siloed approach. The typical projects within a data center transformation initiative include standardization/consolidation, virtualization, automation and security.\r\n<ul><li>Standardization/consolidation: Reducing the number of data centers and avoiding server sprawl (both physical and virtual) often includes replacing aging data center equipment, and is aided by standardization.</li><li>Virtualization: Lowers capital and operational expenses, reduce energy consumption.

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network.

The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png"},{"id":471,"title":"Hardware","alias":"hardware","description":" Computer hardware includes the physical, tangible parts or components of a computer, such as the cabinet, central processing unit, monitor, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is instructions that can be stored and run by hardware. Hardware is so-termed because it is "hard" or rigid with respect to changes or modifications; whereas software is "soft" because it is easy to update or change. Intermediate between software and hardware is "firmware", which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface. The progression from levels of "hardness" to "softness" in computer systems parallels a progression of layers of abstraction in computing.\r\nHardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware components.\r\nThe template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms. The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.","materialsDescription":" <span style=\"font-weight: bold; \">What does Hardware (H/W) mean?</span>\r\nHardware (H/W), in the context of technology, refers to the physical elements that make up a computer or electronic system and everything else involved that is physically tangible. This includes the monitor, hard drive, memory and CPU. Hardware works hand-in-hand with firmware and software to make a computer function.\r\n<span style=\"font-weight: bold; \">What are the types of computer systems?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Personal computer</span></span>\r\nThe personal computer, also known as the PC, is one of the most common types of computer due to its versatility and relatively low price. Laptops are generally very similar, although they may use lower-power or reduced size components, thus lower performance.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Case</span></span>\r\nThe computer case encloses and holds most of the components of the system. It provides mechanical support and protection for internal elements such as the motherboard, disk drives, and power supplies, and controls and directs the flow of cooling air over internal components. The case is also part of the system to control electromagnetic interference radiated by the computer, and protects internal parts from electrostatic discharge. Large tower cases provide extra internal space for multiple disk drives or other peripherals and usually stand on the floor, while desktop cases provide less expansion room. All-in-one style designs include a video display built into the same case. Portable and laptop computers require cases that provide impact protection for the unit. A current development in laptop computers is a detachable keyboard, which allows the system to be configured as a touch-screen tablet. Hobbyists may decorate the cases with colored lights, paint, or other features, in an activity called case modding.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power supply</span></span>\r\nA power supply unit (PSU) converts alternating current (AC) electric power to low-voltage direct current (DC) power for the internal components of the computer. Laptops are capable of running from a built-in battery, normally for a period of hours. The PSU typically uses a switched-mode power supply (SMPS), with power MOSFETs (power metal–oxide–semiconductor field-effect transistors) used in the converters and regulator circuits of the SMPS.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Motherboard</span></span>\r\nThe motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. The integrated circuit (IC) chips in a computer typically contain billions of tiny metal–oxide–semiconductor field-effect transistors (MOSFETs).\r\nComponents directly attached to or to part of the motherboard include:\r\n<ul><li><span style=\"font-weight: bold; \">The CPU (central processing unit)</span>, which performs most of the calculations which enable a computer to function, and is referred to as the brain of the computer which get a hold of program instruction from random-access memory (RAM), interprets and processes it and then send it backs to computer result so that the relevant components can carry out the instructions. The CPU is a microprocessor, which is fabricated on a metal–oxide–semiconductor (MOS) integrated circuit (IC) chip. It is usually cooled by a heat sink and fan, or water-cooling system. Most newer CPU include an on-die graphics processing unit (GPU). The clock speed of CPU governs how fast it executes instructions, and is measured in GHz; typical values lie between 1 GHz and 5 GHz. Many modern computers have the option to overclock the CPU which enhances performance at the expense of greater thermal output and thus a need for improved cooling.</li><li><span style=\"font-weight: bold; \">The chipset</span>, which includes the north bridge, mediates communication between the CPU and the other components of the system, including main memory; as well as south bridge, which is connected to the north bridge, and supports auxiliary interfaces and buses; and, finally, a Super I/O chip, connected through the south bridge, which supports the slowest and most legacy components like serial ports, hardware monitoring and fan control.</li><li><span style=\"font-weight: bold; \">Random-access memory (RAM)</span>, which stores the code and data that are being actively accessed by the CPU. For example, when a web browser is opened on the computer it takes up memory; this is stored in the RAM until the web browser is closed. It is typically a type of dynamic RAM (DRAM), such as synchronous DRAM (SDRAM), where MOS memory chips store data on memory cells consisting of MOSFETs and MOS capacitors. RAM usually comes on dual in-line memory modules (DIMMs) in the sizes of 2GB, 4GB, and 8GB, but can be much larger.</li><li><span style=\"font-weight: bold; \">Read-only memory (ROM)</span>, which stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or "booting" or "booting up". The ROM is typically a nonvolatile BIOS memory chip, which stores data on floating-gate MOSFET memory cells.</li><li><span style=\"font-weight: bold; \">The BIOS (Basic Input Output System)</span> includes boot firmware and power management firmware. Newer motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS.</li><li><span style=\"font-weight: bold; \">Buses</span> that connect the CPU to various internal components and to expand cards for graphics and sound.</li><li><span style=\"font-weight: bold; \">The CMOS</span> (complementary MOS) battery, which powers the CMOS memory for date and time in the BIOS chip. This battery is generally a watch battery.</li><li><span style=\"font-weight: bold; \">The video card</span> (also known as the graphics card), which processes computer graphics. More powerful graphics cards are better suited to handle strenuous tasks, such as playing intensive video games or running computer graphics software. A video card contains a graphics processing unit (GPU) and video memory (typically a type of SDRAM), both fabricated on MOS integrated circuit (MOS IC) chips.</li><li><span style=\"font-weight: bold; \">Power MOSFETs</span> make up the voltage regulator module (VRM), which controls how much voltage other hardware components receive.</li></ul>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Expansion cards</span></span>\r\nAn expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansion cards can be used to obtain or expand on features not offered by the motherboard.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Storage devices</span></span>\r\nA storage device is any computing hardware and digital media that is used for storing, porting and extracting data files and objects. It can hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device. Data storage is a core function and fundamental component of computers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Fixed media</span></span>\r\nData is stored by a computer using a variety of media. Hard disk drives (HDDs) are found in virtually all older computers, due to their high capacity and low cost, but solid-state drives (SSDs) are faster and more power efficient, although currently more expensive than hard drives in terms of dollar per gigabyte, so are often found in personal computers built post-2007. SSDs use flash memory, which stores data on MOS memory chips consisting of floating-gate MOSFET memory cells. Some systems may use a disk array controller for greater performance or reliability.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Removable media</span></span>\r\nTo transfer data between computers, an external flash memory device (such as a memory card or USB flash drive) or optical disc (such as a CD-ROM, DVD-ROM or BD-ROM) may be used. Their usefulness depends on being readable by other systems; the majority of machines have an optical disk drive (ODD), and virtually all have at least one Universal Serial Bus (USB) port.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input and output peripherals</span></span>\r\nInput and output devices are typically housed externally to the main computer chassis. The following are either standard or very common to many computer systems.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input</span></span>\r\nInput devices allow the user to enter information into the system, or control its operation. Most personal computers have a mouse and keyboard, but laptop systems typically use a touchpad instead of a mouse. Other input devices include webcams, microphones, joysticks, and image scanners.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Output device</span></span>\r\nOutput devices display information in a human readable form. Such devices could include printers, speakers, monitors or a Braille embosser.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Mainframe computer</span></span>\r\nA mainframe computer is a much larger computer that typically fills a room and may cost many hundreds or thousands of times as much as a personal computer. They are designed to perform large numbers of calculations for governments and large enterprises.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Departmental computing</span></span>\r\nIn the 1960s and 1970s, more and more departments started to use cheaper and dedicated systems for specific purposes like process control and laboratory automation.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Supercomputer</span></span>\r\nA supercomputer is superficially similar to a mainframe, but is instead intended for extremely demanding computational tasks. As of June 2018, the fastest supercomputer on the TOP500supercomputer list is the Summit, in the United States, with a LINPACK benchmarkscore of 122.3 PFLOPS Light, by around 29 PFLOPS.\r\nThe term supercomputer does not refer to a specific technology. Rather it indicates the fastest computations available at any given time. In mid 2011, the fastest supercomputers boasted speeds exceeding one petaflop, or 1 quadrillion (10^15 or 1,000 trillion) floating point operations per second. Supercomputers are fast but extremely costly, so they are generally used by large organizations to execute computationally demanding tasks involving large data sets. Supercomputers typically run military and scientific applications. Although costly, they are also being used for commercial applications where huge amounts of data must be analyzed. For example, large banks employ supercomputers to calculate the risks and returns of various investment strategies, and healthcare organizations use them to analyze giant databases of patient data to determine optimal treatments for various diseases and problems incurring to the country.

Companies use SCADA systems to control equipment across their sites and to collect and record data about their operations. SCADA is not a specific technology, but a type of application. Any application that gets operating data about a system in order to control and optimise that system is a SCADA application. That application may be a petrochemical distillation process, a water filtration system, a pipeline compressor, or just about anything else.\r\nSCADA solutions typically come in a combination of software and hardware elements, such as programmable logic controllers (PLCs) and remote terminal units (RTUs). Data acquisition in SCADA starts with PLCs and RTUs, which communicate with plant floor equipment such as factory machinery and sensors. Data gathered from the equipment is then sent to the next level, such as a control room, where operators can supervise the PLC and RTU controls using human-machine interfaces (HMIs). HMIs are an important element of SCADA systems. They are the screens that operators use to communicate with the SCADA system.\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">The major components of a SCADA technology include:</span></p>\r\n<ul><li><span style=\"font-weight: bold;\">Master Terminal Unit (MTU).</span> It comprises a computer, PLC and a network server that helps MTU to communicate with the RTUs.

When you tell a SCADA communication network, it is defined as a link between RTU in the field to MTU in the central location.

Various other communication mediums like fiber optic cables, twisted pair cables, etc. are also used.</li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">Objectives of Supervisory Control and Data Acquisition system</span></p>\r\n<ul><li><span style=\"font-weight: bold;\">Monitor:</span> SCADA control system continuously monitors the physical parameters</li><li><span style=\"font-weight: bold;\">Measure:</span> It measures the parameter for processing</li><li><span style=\"font-weight: bold;\">Data Acquisition:</span> It acquires data from RTU, data loggers, etc</li><li><span style=\"font-weight: bold;\">Data Communication:</span> It helps to communicate and transmit a large amount of data between MTU and RTU units</li><li><span style=\"font-weight: bold;\">Controlling:</span> Online real-time monitoring and controlling of the process</li><li><span style=\"font-weight: bold;\">Automation:</span> It helps for automatic transmission and functionality</li></ul>\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Who Uses SCADA?</h1>\r\nSCADA systems are used by industrial organizations and companies in the public and private sectors to control and maintain efficiency, distribute data for smarter decisions, and communicate system issues to help mitigate downtime. Supervisory control systems work well in many different types of enterprises because they can range from simple configurations to large, complex installations. They are the backbone of many modern industries, including:\r\n<ul><li>Energy</li><li>Food and beverage</li><li>Manufacturing</li><li>Oil and gas</li><li>Power</li><li>Recycling</li><li>Transportation</li><li>Water and waste water</li><li>And many more</li></ul>\r\nVirtually anywhere you look in today's world, there is some type of SCADA monitoring system running behind the scenes: maintaining the refrigeration systems at the local supermarket, ensuring production and safety at a refinery, achieving quality standards at a waste water treatment plant, or even tracking your energy use at home, to give a few examples. Effective SCADA systems can result in significant savings of time and money. Numerous case studies have been published highlighting the benefits and savings of using a modern SCADA software.\r\n<h1 class=\"align-center\">Benefits of using SCADA software</h1>\r\nUsing modern SCADA software provides numerous benefits to businesses, and helps companies make the most of those benefits. Some of these advantages include:\r\n<span style=\"font-weight: bold; \">Easier engineering:</span> An advanced supervisory control application such provides easy-to-locate tools, wizards, graphic templates and other pre-configured elements, so engineers can create automation projects and set parameters quickly, even if they don't have programming experience. In addition, you can also easily maintain and expand existing applications as needed. The ability to automate the engineering process allows users, particularly system integrators and original equipment manufacturers (OEM), to set up complex projects much more efficiently and accurately.\r\n<span style=\"font-weight: bold; \">Improved data management:</span> A high-quality SCADA system makes it easier to collect, manage, access and analyze your operational data. It can enable automatic data recording and provide a central location for data storage. Additionally, it can transfer data to other systems such as MES and ERP as needed. \r\n<span style=\"font-weight: bold; \">Greater visibility:</span> One of the main advantages of using SCADA software is the improvement in visibility into your operations. It provides you with real-time information about your operations and enables you to conveniently view that information via an HMI. SCADA monitoring can also help in generating reports and analyzing data.\r\n<span style=\"font-weight: bold; \">Enhanced efficiency:</span> A SCADA system allows you to streamline processes through automated actions and user-friendly tools. The data that SCADA provides allows you to uncover opportunities for improving the efficiency of the operations, which can be used to make long-term changes to processes or even respond to real-time changes in conditions.\r\n<span style=\"font-weight: bold; \">Increased usability:</span> SCADA systems enable workers to control equipment more quickly, easily and safely through an HMI. Rather than having to control each piece of machinery manually, workers can manage them remotely and often control many pieces of equipment from a single location. Managers, even those who are not currently on the floor, also gain this capability.\r\n<span style=\"font-weight: bold; \">Reduced downtime:</span> A SCADA system can detect faults at an early stage and push instant alerts to the responsible personnel. Powered by predictive analytics, a SCADA system can also inform you of a potential issue of the machinery before it fails and causes larger problems. These features can help improve the overall equipment effectiveness (OEE) and reduce the amount of time and cost on troubleshooting and maintenance.\r\n<span style=\"font-weight: bold;\">Easy integration:</span> Connectivity to existing machine environments is key to removing data silos and maximizing productivity. \r\n<span style=\"font-weight: bold;\">Unified platform:</span>All of your data is also available in one platform, which helps you to get a clear overview of your operations and take full advantage of your data. All users also get real-time updates locally or remotely, ensuring everyone on your team is on the same page.<br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/SCADA__-_Supervisory_Control_And_Data_Acquisition.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":5081,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/HP_ProLiant_DL380__DL_380_G5_.jpg","logo":true,"scheme":false,"title":"HP ProLiant DL380 G5","vendorVerified":0,"rating":"0.00","implementationsCount":2,"suppliersCount":0,"supplierPartnersCount":452,"alias":"hp-proliant-dl380-g5","companyTitle":"Hewlett Packard Enterprise","companyTypes":["supplier","vendor"],"companyId":172,"companyAlias":"hewlett-packard-enterprise","description":"The new HP ProLiant DL380 (DL 380 G5), the largest server in the world, confirms its reputation as a server with unsurpassed uptime and enterprise-level manageability, high performance of two Intel Xeon processors.

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server.

CorreLog SIEM incorporates various reporting facilities, including an Excel-based reporting facility that populates spreadsheets with summary and detailed event information, and an ODBC reporting facility that populates one or more databases with report information to support third-party report writers. Additionally, CorreLog SIEM includes a comprehensive dashboard facility, a "Pivot" log analyzer (for analyzing firewall data, HTTP server logs, and other "regular" data) and comprehensive graphing utilities useful for reporting on correlation results. The CorreLog Server comes preconfigured with compliancy reports and correlation rules to support these reports. Additional report templates can be loaded (or saved) using a built-in "Template" facility.</span></li></ul>\r\n\r\n<ul><li><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"><span style=\"font-weight: bold;\">Data Aggregation and Archiving Functions.</span> The CorreLog SIEM system can aggregate vast amounts of data. It can collect in excess of 1 Gigabyte of data each day at a single site, and save this data online for up to 500 days (given enough storage.) Additionally, CorreLog SIEM compresses and archives your data, retaining this data for a period of more than 10 years (5000 days). To assist in forensics and long-term analysis, CorreLog SIEM generates archival data such as MD5 checksums and Security Codes.</span></li></ul>\r\n\r\n<ul><li><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"><span style=\"font-weight: bold;\">Data Searching Ability.</span> One of the most important functions of the CorreLog SIEM system program is its search capability. CorreLog SIEM uses its proprietary GenDex (Generate Data Extraction) program, which employs a high speed, real time index system. This allows quick searches through massive amounts of message data. The performance of this engine rivals the fastest search engines currently available. Users can search a terabyte of data for a particular keyword in less than one second.</span><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"></span><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"></span></li></ul>\r\n\r\n<ul><li><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"><span style=\"font-weight: bold;\">Taxonomy, Ontology, and Catalog Functions.</span> Taxonomy and categorization of data is at the center of our unique correlation system. The CorreLog SIEM Server automatically catalogs information by IP address, username, facility, and severity. Users can further create catalogs of information based upon simple or complex match patterns. Data is cataloged based upon specifications consisting of simple keywords, wildcards and regular expressions, logical expressions of wildcards, macro definitions of regular expressions, and logical combinations of macros. This provides a complete flexibility in managing and grouping message data, while still maintaining high data throughputs, and avoiding the rigors of data normalization.</span><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"></span></li></ul>\r\n\r\n<ul><li><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"><span style=\"font-weight: bold;\">Ability To Define New Syslog Facilities.</span> One of the commonly noticed limitations of Syslog protocol has always been that the "Facility" codes (which define the data sources for syslog messages) are limited to 24 predefined codes. The CorreLog program removes this restriction, permitting users to define their own facilities, such as "applications", and "devmsgs", so that data can be better categorized and managed. This important extension to the syslog protocol opens important new vistas in the practical use of Syslog messages and their correlation, not otherwise available using the standard specification.</span><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"></span><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"></span></li></ul>\r\n\r\n<ul><li><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"><span style=\"font-weight: bold;\">Ability To Override Message Content. </span>One of the commonly noticed limitations of SNMP Trap and Syslog protocol has always been that, since messages are unsolicited, the message collector is stuck with whatever message, severity, or facility was originally specified by the message sender. In some cases the severities or facilities within a message may be nonsensical. The CorreLog program recognizes this existing limitation and implements a sophisticated "override" scheme, which allows users to override the facility, severity, or device name in any message. This greatly assists with the control and correlation of data.</span></li></ul>\r\n\r\n<ul><li><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"><span style=\"font-weight: bold;\">Input Filtering.</span> To reduce data loading, and permit precise control over incoming messages, CorreLog SIEM can filter input data by device, facility, severity, message keyword, time of day, or any combination of these. Filtered data can be discarded, or put into a separate repository (and possibly permanently archived) for further analysis or forensics. When data is filtered, it is automatically tagged with the particular filter expression, assisting in the analysis of filtered data. CorreLog treats filtered data with respect, permitting you to re-import discarded data and undo any particular filtering function.</span><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"></span><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"></span></li></ul>\r\n\r\n<ul><li><span style=\"font-size:11pt; font-family:Arial; color:#000000; background-color:transparent; font-weight:400; font-style:normal; font-variant:normal; text-decoration:none; vertical-align:baseline; white-space:pre; white-space:pre-wrap; \"><span style=\"font-weight: bold;\">Automatic Remediation And Response.</span> The CorreLog SIEM system incorporates a simple and extensible "Actions" capability, which permits you to target specific messages based upon device, keyword, facility, severity and/ or time of day, and run programs on that data.

The main reason is that every user or tracker leaves behind a virtual trail in a network’s log data. SIEM software is designed to use this log data in order to generate insight into past attacks and events. A SIEM solution not only identifies that an attack has happened, but allows you to see how and why it happened as well.\r\nAs organizations update and upscale to increasingly complex IT infrastructures, SIEM has become even more important in recent years. Contrary to popular belief, firewalls and antivirus packages are not enough to protect a network in its entirety. Zero-day attacks can still penetrate a system’s defenses even with these security measures in place.\r\nSIEM addresses this problem by detecting attack activity and assessing it against past behavior on the network. A security event monitoring has the ability to distinguish between legitimate use and a malicious attack. This helps to increase a system’s incident protection and avoid damage to systems and virtual property.\r\nThe use of SIEM also helps companies to comply with a variety of industry cyber management regulations. Log management is the industry standard method of auditing activity on an IT network. SIEM management provides the best way to meet this regulatory requirement and provide transparency over logs in order to generate clear insights and improvements.\r\n<h1 class=\"align-center\">Evaluation criteria for security information and event management software:</h1>\r\n<ul><li>Threat identification: Raw log form vs. descriptive.</li><li>Threat tracking: Ability to track through the various events, from source to destination.</li><li>Policy enforcement: Ability to enforce defined polices.</li><li>Application analysis: Ability to analyze application at Layer 7 if necessary.</li><li>Business relevance of events: Ability to assign business risk to events and have weighted threat levels.</li><li>Measuring changes and improvements: Ability to track configuration changes to devices.</li><li>Asset-based information: Ability to gather information on devices on the network.</li><li>Anomalous behavior (server): Ability to trend and see changes in how it communicates to others.</li><li>Anomalous behavior (network): Ability to trend and see how communications pass throughout the network.</li><li>Anomalous behavior (application): Ability to trend and see changes in how it communicates to others.</li><li>User monitoring: User activity, logging in, applications usage, etc.</li></ul>\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_SIEM.png"},{"id":513,"title":"Networking","alias":"networking","description":" Networking hardware, also known as network equipment or computer networking devices, are electronic devices which are required for communication and interaction between devices on a computer network.

Units which are the last receiver or generate data are called hosts or data terminal equipment.\r\nNetworking devices may include gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters; and may also include hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.\r\nThe most common kind of networking hardware today is a copper-based Ethernet adapter which is a standard inclusion on most modern computer systems. Wireless networking has become increasingly popular, especially for portable and handheld devices.\r\nOther networking hardware used in computers includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery.\r\nTaking a wider view, mobile phones, tablet computers and devices associated with the internet of things may also be considered networking hardware. As technology advances and IP-based networks are integrated into building infrastructure and household utilities, network hardware will become an ambiguous term owing to the vastly increasing number of network capable endpoints.","materialsDescription":" <span style=\"font-weight: bold;\">What is network equipment?</span>\r\nNetwork equipment - devices necessary for the operation of a computer network, for example: a router, switch, hub, patch panel, etc. You can distinguish between active and passive network equipment.\r\n<span style=\"font-weight: bold;\">What is an active network equipment?</span>\r\nActive networking equipment is equipment followed by some “smart” feature.

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network.

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network.

A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service.

The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client.

Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network.

In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png"},{"id":7,"title":"Storage - General-Purpose Disk Arrays","alias":"storage-general-purpose-disk-arrays","description":" General-purpose disk arrays refer to disk storage systems that work together with specialized array controllers to achieve high data transfer.

These core characteristics are volatility, mutability, accessibility, and addressability. For any particular implementation of any storage technology, the characteristics worth measuring are capacity and performance.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Volatility</span></span>\r\nNon-volatile memory retains the stored information even if not constantly supplied with electric power. It is suitable for long-term storage of information. Volatile memory requires constant power to maintain the stored information. The fastest memory technologies are volatile ones, although that is not a universal rule. Since the primary storage is required to be very fast, it predominantly uses volatile memory.\r\nDynamic random-access memory is a form of volatile memory that also requires the stored information to be periodically reread and rewritten, or refreshed, otherwise it would vanish. Static random-access memory is a form of volatile memory similar to DRAM with the exception that it never needs to be refreshed as long as power is applied; it loses its content when the power supply is lost.\r\nAn uninterruptible power supply (UPS) can be used to give a computer a brief window of time to move information from primary volatile storage into non-volatile storage before the batteries are exhausted. Some systems, for example EMC Symmetrix, have integrated batteries that maintain volatile storage for several minutes.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Mutability</span></span>\r\n<span style=\"font-weight: bold;\">Read/write storage or mutable storage</span>\r\n<div class=\"indent\">Allows information to be overwritten at any time. A computer without some amount of read/write storage for primary storage purposes would be useless for many tasks. Modern computers typically use read/write storage also for secondary storage.</div>\r\n<span style=\"font-weight: bold;\">Slow write, fast read storage</span>\r\n<div class=\"indent\">Read/write storage which allows information to be overwritten multiple times, but with the write operation being much slower than the read operation. Examples include CD-RW and SSD.</div>\r\n<span style=\"font-weight: bold;\">Write once storage</span>\r\n<div class=\"indent\">Write Once Read Many (WORM) allows the information to be written only once at some point after manufacture. Examples include semiconductor programmable read-only memory and CD-R.</div>\r\n<span style=\"font-weight: bold;\">Read only storage</span>\r\n<div class=\"indent\">Retains the information stored at the time of manufacture. Examples include mask ROM ICs and CD-ROM.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Accessibility</span></span>\r\n<span style=\"font-weight: bold;\">Random access</span>\r\n<div class=\"indent\">Any location in storage can be accessed at any moment in approximately the same amount of time. Such characteristic is well suited for primary and secondary storage. Most semiconductor memories and disk drives provide random access.</div>\r\n<span style=\"font-weight: bold;\">Sequential access</span>\r\n<div class=\"indent\">The accessing of pieces of information will be in a serial order, one after the other; therefore the time to access a particular piece of information depends upon which piece of information was last accessed. Such characteristic is typical of off-line storage.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Addressability</span></span>\r\n<span style=\"font-weight: bold;\">Location-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information in storage is selected with its numerical memory address. In modern computers, location-addressable storage usually limits to primary storage, accessed internally by computer programs, since location-addressability is very efficient, but burdensome for humans.</div>\r\n<span style=\"font-weight: bold;\">File addressable</span>\r\n<div class=\"indent\">Information is divided into files of variable length, and a particular file is selected with human-readable directory and file names. The underlying device is still location-addressable, but the operating system of a computer provides the file system abstraction to make the operation more understandable. In modern computers, secondary, tertiary and off-line storage use file systems.</div>\r\n<span style=\"font-weight: bold;\">Content-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information is selected based on the basis of (part of) the contents stored there. Content-addressable storage can be implemented using software (computer program) or hardware (computer device), with hardware being faster but more expensive option. Hardware content addressable memory is often used in a computer's CPU cache.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Capacity</span></span>\r\n<span style=\"font-weight: bold;\">Raw capacity</span>\r\n<div class=\"indent\">The total amount of stored information that a storage device or medium can hold. It is expressed as a quantity of bits or bytes (e.g. 10.4 megabytes).</div>\r\n<span style=\"font-weight: bold;\">Memory storage density</span>\r\n<div class=\"indent\">The compactness of stored information. It is the storage capacity of a medium divided with a unit of length, area or volume (e.g. 1.2 megabytes per square inch).</div>\r\n\r\n<span style=\"font-weight: bold;\"><span style=\"font-style: italic;\">Performance</span></span>\r\n<span style=\"font-weight: bold;\">Latency</span>\r\n<div class=\"indent\">The time it takes to access a particular location in storage. The relevant unit of measurement is typically nanosecond for primary storage, millisecond for secondary storage, and second for tertiary storage. It may make sense to separate read latency and write latency (especially for non-volatile memory[8]) and in case of sequential access storage, minimum, maximum and average latency.</div>\r\n<span style=\"font-weight: bold;\">Throughput</span>\r\n<div class=\"indent\">The rate at which information can be read from or written to the storage. In computer data storage, throughput is usually expressed in terms of megabytes per second (MB/s), though bit rate may also be used. As with latency, read rate and write rate may need to be differentiated. Also accessing media sequentially, as opposed to randomly, typically yields maximum throughput.</div>\r\n<span style=\"font-weight: bold;\">Granularity</span>\r\n<div class=\"indent\">The size of the largest "chunk" of data that can be efficiently accessed as a single unit, e.g. without introducing additional latency.</div>\r\n<span style=\"font-weight: bold;\">Reliability</span>\r\n<div class=\"indent\">The probability of spontaneous bit value change under various conditions, or overall failure rate.</div>\r\nUtilities such as hdparm and sar can be used to measure IO performance in Linux.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Energy use</span></span>\r\n<ul><li>Storage devices that reduce fan usage, automatically shut-down during inactivity, and low power hard drives can reduce energy consumption by 90 percent.</li><li>2.5-inch hard disk drives often consume less power than larger ones. Low capacity solid-state drives have no moving parts and consume less power than hard disks. Also, memory may use more power than hard disks. Large caches, which are used to avoid hitting the memory wall, may also consume a large amount of power.</li></ul>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Security</span></span>\r\nFull disk encryption, volume and virtual disk encryption, andor file/folder encryption is readily available for most storage devices.\r\nHardware memory encryption is available in Intel Architecture, supporting Total Memory Encryption (TME) and page granular memory encryption with multiple keys (MKTME) and in SPARC M7 generation since October 2015.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Storage_General_Purpose_Disk_Arrays.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[{"id":33,"title":"UPS - Uninterruptible Power Supply"},{"id":56,"title":"Router"},{"id":542,"title":"UTM - Unified Threat Management Appliance"}],"solutions":["Aging IT infrastructure"],"materials":[],"useCases":[],"best_practices":[],"values":["Ensure Security and Business Continuity","Reduce Costs"],"implementations":[],"presenterCodeLng":"","productImplementations":[]}},"aliases":{},"links":{},"meta":{},"loading":false,"error":null,"useProductLoading":false,"sellProductLoading":false,"templatesById":{},"comparisonByTemplateId":{}},"filters":{"filterCriterias":{"loading":false,"error":null,"data":{"price":{"min":0,"max":6000},"users":{"loading":false,"error":null,"ids":[],"values":{}},"suppliers":{"loading":false,"error":null,"ids":[],"values":{}},"vendors":{"loading":false,"error":null,"ids":[],"values":{}},"roles":{"id":200,"title":"Roles","values":{"1":{"id":1,"title":"User","translationKey":"user"},"2":{"id":2,"title":"Supplier","translationKey":"supplier"},"3":{"id":3,"title":"Vendor","translationKey":"vendor"}}},"categories":{"flat":[],"tree":[]},"countries":{"loading":false,"error":null,"ids":[],"values":{}}}},"showAIFilter":false},"companies":{"companiesByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"implementations":{"implementationsByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"agreements":{"agreementById":{},"ids":{},"links":{},"meta":{},"loading":false,"error":null},"comparison":{"loading":false,"error":false,"templatesById":{},"comparisonByTemplateId":{},"products":[],"selectedTemplateId":null},"presentation":{"type":null,"company":{},"products":[],"partners":[],"formData":{},"dataLoading":false,"dataError":false,"loading":false,"error":false},"catalogsGlobal":{"subMenuItemTitle":""}}
