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 &quot;chunk&quot; 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","alias":"storage-general-purpose-disk-arrays"},"35":{"id":35,"title":"Server","description":"In computing, a server is a computer program or a device that provides functionality for other programs or devices, called &quot;clients&quot;. 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 &quot;services&quot;, 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 &quot;server-class hardware&quot; 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 &quot;servers serve users&quot; (and &quot;users use servers&quot;), in the sense of &quot;obey&quot;, today one often says that &quot;servers serve data&quot;, in the same sense as &quot;give&quot;. For instance, web servers &quot;serve web pages to users&quot; or &quot;service their requests&quot;.\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 &quot;server&quot; 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 &quot;computerhope.com&quot;), 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","alias":"server"},"37":{"id":37,"title":"PC - personal computer","description":"A personal computer (PC) is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large costly minicomputer and mainframes, time-sharing by many people at the same time is not used with personal computers.\r\nInstitutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. While personal computer users may develop their own applications, usually these systems run commercial software, free-of-charge software (&quot;freeware&quot;), which is most often proprietary, or free and open-source software, which is provided in &quot;ready-to-run&quot;, or binary, form. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. Many personal computer users no longer need to write their own programs to make any use of a personal computer, although end-user programming is still feasible. This contrasts with mobile systems, where software is often only available through a manufacturer-supported channel, and end-user program development may be discouraged by lack of support by the manufacturer.\r\nSince the early 1990s, Microsoft operating systems and Intel hardware have dominated much of the personal computer market, first with MS-DOS and then with Microsoft Windows. Alternatives to Microsoft's Windows operating systems occupy a minority share of the industry. These include Apple's macOS and free and open-source Unix-like operating systems.\r\nThe advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people in all countries.\r\n&quot;PC&quot; is an initialism for &quot;personal computer&quot;. The IBM Personal Computer incorporated the designation in its model name. It is sometimes useful to distinguish personal computers of the &quot;IBM Personal Computer&quot; family from personal computers made by other manufacturers. For example, &quot;PC&quot; is used in contrast with &quot;Mac&quot;, an Apple Macintosh computer. Since none of these Apple products were mainframes or time-sharing systems, they were all &quot;personal computers&quot; and not &quot;PC&quot; (brand) computers.","materialsDescription":" <span style=\"font-weight: bold;\">What types of stationary personal computers exist?</span>\r\n<span style=\"font-weight: bold;\">Desktops</span> - refer to the type of stationary PC. From the name it is clear that these are devices that are installed and work on a table and are not transferred during operation. As a rule, representatives of this group are high-performance powerful devices. They consist of a system unit (a rectangular box), to which a monitor, keyboard and mouse are connected.\r\n<span style=\"font-weight: bold;\">Servers</span> - this type of computer has its own specific tasks that it performs remotely or locally in place. The vast majority of servers are quite powerful machines. The appearance of the servers is slightly different from the usual PC - they are mounted in metal racks that look like furniture shelves. The racks themselves are placed in a special room (server room), the necessary temperature regime is necessarily maintained in it.\r\n<span style=\"font-weight: bold;\">Nettops</span> - refer to the type of stationary PC. The system unit is compact in size, usually with low power consumption and noise. Due to the small size, nettops have lower performance, but they fit perfectly into the home environment and do not occupy expensive office space.\r\n<span style=\"font-weight: bold;\">Microcomputers</span> are computers that fit in a miniature enclosure that looks very similar to a flash drive. The microcomputer itself does not have an output device, therefore, through an HDMI connection, it connects to a monitor or TV. Controls, such as a mouse or keyboard, are connected via the built-in USB ports or Bluetooth. Technical specifications depend on the configuration, as with any other PC.\r\n<span style=\"font-weight: bold;\">Monoblocks</span> - refer to the type of stationary PC. The system unit and the monitor are a single unit. Accessories and boards are placed in the compartment, which is mounted on the back of the monitor. It has an aesthetic appearance and does not take up much space.\r\n<span style=\"font-weight: bold;\">What are the types of portable personal computers?</span>\r\nA laptop computer can also be called portable. They differ from desktop dimensions and weight in a smaller direction and more capacious batteries, which is understandable because you need to carry it with you.\r\n<span style=\"font-weight: bold;\">Laptops and netbooks</span> - refer to the type of portable (laptop) PCs, have a battery for offline operation without using a network. The case is made in the form of a clamshell, a screen is installed at the top, and a keyboard at the bottom. Netbooks are smaller than laptops, respectively, have lower performance, although the battery life is longer.\r\n<span style=\"font-weight: bold;\">Tablet laptops</span> - refer to the type of portable (laptop) PC. The case consists of a touch screen display - Touchscreen. Their main purpose is surfing the Internet, watching videos, listening to audio, gaming and other applications. The compact dimensions make this group especially popular for travelers. Tablet laptops have a keyboard that either folds up or extends out of a niche under the screen. In tablets, the touchscreen is the input medium. For this group, battery life is important.\r\n<span style=\"font-weight: bold;\">Pocket PCs and smartphones</span> - belong to the type of portable (laptop) PC. Distinctive features are a small size and a large reserve of battery life. The input tool is either a touch screen or a retractable keyboard.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_PC.png","alias":"pc-personal-computer"},"38":{"id":38,"title":"Tablet PC","description":"A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, do what other personal computers do, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only difference being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network.\r\nThe touchscreen display is operated by gestures executed by finger or digital pen (stylus), instead of the mouse, trackpad, and keyboard of larger computers. Portable computers can be classified according to the presence and appearance of physical keyboards. Two species of a tablet, the slate and booklet, do not have physical keyboards and usually accept text and other input by use of a virtual keyboard shown on their touchscreen displays. To compensate for their lack of a physical keyboard, most tablets can connect to independent physical keyboards by Bluetooth or USB; 2-in-1 PCs have keyboards, distinct from tablets.\r\nThe form of the tablet was conceptualized in the middle of the 20th century (Stanley Kubrick depicted fictional tablets in the 1968 science fiction film A Space Odyssey) and prototyped and developed in the last two decades of that century. In 2010, Apple released the iPad, the first mass-market tablet to achieve widespread popularity. Thereafter tablets rapidly rose in ubiquity and soon became a large product category used for personal, educational and workplace applications, with sales stabilizing in the mid-2010s.\r\nAndroid was the first of the 2000s-era dominating platforms for tablet computers to reach the market. In 2008, the first plans for Android-based tablets appeared. The first products were released in 2009. Among them was the Archos 5, a pocket-sized model with a 5-inch touchscreen, that was first released with a proprietary operating system and later (in 2009) released with Android 1.4. The Camangi WebStation was released in Q2 2009. The first LTE Android tablet appeared in late 2009 and was made by ICD for Verizon. This unit was called the Ultra, but a version called Vega was released around the same time. Ultra had a 7-inch display while Vega's was 15 inches. Many more products followed in 2010. Several manufacturers waited for Android Honeycomb, specifically adapted for use with tablets, which debuted in February 2011.\r\nApple is often credited for defining a new class of consumer device with the iPad, which shaped the commercial market for tablets in the following years, and was the most successful tablet at the time of its release. iPads and competing devices were tested by the US military in 2011 and cleared for secure use in 2013. Its debut in 2010 pushed tablets into the mainstream. Samsung's Galaxy Tab and others followed, continuing the trends towards the features listed above. In March 2012, PC Magazine reported that 31% of U.S. Internet users owned a tablet, used mainly for viewing published content such as video and news. The top-selling line of devices was Apple's iPad with 100 million sold between its release in April 2010 and mid-October 2012, but iPad market share (number of units) dropped to 36% in 2013 with Android tablets climbing to 62%. Android tablet sales volume was 121 million devices, plus 52 million, between 2012 and 2013 respectively. Individual brands of Android operating system devices or compatibles follow iPad with Amazon's Kindle Fire with 7 million, and Barnes &amp; Noble's Nook with 5 million.\r\nThe BlackBerry PlayBook was announced in September 2010 that ran the BlackBerry Tablet OS. The BlackBerry PlayBook was officially released to US and Canadian consumers on April 19, 2011. Hewlett Packard announced that the TouchPad, running WebOS 3.0 on a 1.2 GHz Qualcomm Snapdragon CPU, would be released in June 2011. On August 18, 2011, HP announced the discontinuation of the TouchPad, due to sluggish sales.[66] In 2013, the Mozilla Foundation announced a prototype tablet model with Foxconn which ran on Firefox OS. Firefox OS was discontinued in 2016. The Canonical hinted that Ubuntu would be available on tablets by 2014. In February 2016 there was a commercial release of the BQ Aquaris Ubuntu tablet utilizing the Ubuntu Touch operating system. Canonical terminated support for the project due to lack of market interest on 5 April 2017 and it was then adopted by the UBports as a community project.\r\nAs of February 2014, 83% of mobile app developers were targeting tablets, but 93% of developers were targeting smartphones. By 2014 around 23% of B2B companies were said to have deployed tablets for sales-related activities, according to a survey report by Corporate Visions. The iPad held majority use in North America, Western Europe, Japan, Australia, and most of the Americas. Android tablets were more popular in most of Asia (China and Russia an exception), Africa and Eastern Europe. In 2015 tablet sales did not increase. Apple remained the largest seller but its market share declined below 25%. Samsung vice president Gary Riding said early in 2016 that tablets were only doing well among those using them for work. Newer models were more expensive and designed for a keyboard and stylus, which reflected the changing uses. As of early 2016, Android reigned over the market with 65%. Apple took the number 2 spot with 26%, and Windows took a distant third with the remaining 9%. In 2018, out of 4.4 billion computing devices, Android accounted for 2 billion, iOS for 1 billion, and the remainder were PCs, in various forms (desktop, notebook, or tablet), running various operating systems (Windows, macOS, ChromeOS, Linux, etc.).","materialsDescription":" <span style=\"font-weight: bold;\">Why are tablet PCs popular?</span>\r\nBy definition, a tablet is a highly portable PC whose primary interface is a touch screen that occupies the full length/width of the device but whose speaker and microphone are not positioned for hand-held calling. In popular perception, however, tablets simply combine the best aspects of smartphones and laptop PCs, creating what tablet lovers consider the ultimate mobile computing experience:\r\n<ul><li>Compatible with home/office wireless and cellular data networks</li><li>Portable, but with larger, clearer displays than earlier mobile devices</li><li>Powerful, but lighter and easier to carry than traditional laptops</li><li>Longer battery life and greater storage capacity than typical smartphones</li></ul>\r\nTablet owners can use touch commands or a virtual keyboard (sometimes a physical one) to run web browsers, email programs, and interactive games just like they do on a desktop PC or laptop. But when they're ready to move, they can keep working (or playing) simply by switching from a home/office wireless network to a cellular data network.\r\n<span style=\"font-weight: bold;\">Are there different types of tablet PCs?</span>\r\nYes and no, depending on the strictness of the definition.\r\nEngineers used the term slate to describe the original, widely popularized tablet PC form factor-- thin and flat, one-sided, without a keyboard. That distinguished tablets from convertibles: full-fledged, keyboard-equipped laptops with hinges that allowed the cover/touch screen to flip 180 degrees -- creating a bulky but usable &quot;tablet.&quot;\r\nToday, the terminology has evolved -- adding the phrase &quot;2-in-1&quot; -- to better distinguish the different types of tablets and laptops. Note that within each category are models that run on mobile operating systems and others that run on regular PC operating systems:\r\n<ul><li><span style=\"font-weight: bold;\">Laptop:</span> The original, portable PC that opens partway, like a notebook, to reveal a screen and a keyboard.</li><li><span style=\"font-weight: bold;\">Tablet:</span> The original, widely popularized slate tablet form factor: thin, flat, and without a keyboard.</li><li><span style=\"font-weight: bold;\">2-in-1 Detachable</span> (also called a &quot;hybrid laptop&quot; or &quot;hybrid tablet&quot;): A device whose keyboard and screen can be fully detached from each other. Depending on the manufacturer, 2-in-1 Detachables might be marketed as &quot;tablets-with-optional-keyboards&quot; or &quot;laptops-with-detachable-tablets.&quot;</li><li><span style=\"font-weight: bold;\">2-in-1 Attached</span> (also called a &quot;convertible laptop&quot; or &quot;convertible tablet&quot;): A device with either a hinge/screen combination that flips around for use as a tablet or a keyboard that in some way folds out from the screen/body. While similar to the original convertibles, today's 2-in-1 Attached models are much thinner and lighter.</li></ul>\r\nIn addition, a new term -- Multimode Tablet -- has emerged to describe models with specialized hinge/handles that allow them to be used traditionally (directly in your hands) or in multiple different ways while propped on a desktop (in tilt mode for easier touch entry (or to project the screen on a nearby wall), in standing mode for touch screen-controlled presentations, or in tent mode for less interactive presentations). Some pc manufacturers even offer a &quot;hanging mode&quot; or include &quot;tablet mode&quot; and &quot;laptop mode&quot; among their list of available modes.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Tablet_PC.png","alias":"tablet-pc"},"435":{"id":435,"title":"Rack Server","description":"A rack mount server is a great way to maximize your shelf space by packing a lot of servers into a small space. Rackmount servers are typically easier for administrators to manage due to proximity, modularity and better cable management. Lockable rack cabinet doors and steel server front panels provide an additional level of physical security. Additionally, rack unit designed servers are better able to keep the server components cool than traditional tower form factor. Industry standard 19-inch racks will allow you to easily expand your business without taking up more valuable floor space.\r\nThere is a lot of thought that needs to go into which size rack server is best bet for your project. Both current requirements and future expansion plans need to be taken into account to ensure your server remains capable in the future.\r\nBoth large and small projects can be built on the 1U server platform. &quot;U&quot; stands for unit, “unit”, and this means thickness: server rack 1U = 1.75 inches or 44 mm wide. A reasonable amount of storage can fit within a 1U, processing power has no limits, and some models even allow up to two PCI-Express cards. Modern computer hardware uses much less power than it ever has in the past, which means less heat generation. Some 1U servers to still produce some acoustic noise, but is nowhere near the level of needing earmuffs like the old days. The only reason to go up in size is for additional expansion options.\r\n2U models allow for multiple &quot;low-profile&quot; PCI-Express cards while keeping a compact form factor and also providing some additional storage space. If the plan is to use multiple full height cards, then 3U or 4U servers should be the focus. The 4U models are very popular and offer flexible options. The 3U models do have limitations on expansion card compatibility and are really only for situations where rack space needs to be absolutely optimized (14x3U servers or 10x4U servers can fit in a 42u rack).","materialsDescription":"<span style=\"font-weight: bold;\">What is a ‘rack unit’?</span>\r\nA rack unit is the designated unit of measurement used when describing or quantifying the vertical space you have available in any equipment rack. One unit is equal to 1.75 inches, or 4.45 centimeters. Any equipment that has the ability to be mounted onto a rack is generally designed in a standard size to fit into many different server rack heights.

So yes, proper ventilation is a critical part of maintaining any data center. Some cabinet manufacturers construct side panel ventilation instead of front and back ventilation, but experts say it’s inadequate for rack mount servers. This can be especially dangerous if more than one cabinet is being set up at once. The importance of proper ventilation should not be taken lightly, and you should always opt for front to back ventilation except in network applications where the IT equipment exhausts out the side.\r\n<span style=\"font-weight: bold;\">What is meant by ‘server rack depth’?</span>\r\nServer rack depth is a critical aspect of the ventilation process. Connectworld.net says, “Server cabinet depth is important not only because it has to allow room for the depth of the particular equipment to be rack-mounted (deep servers vs. routers or switches), but also it has to allow sufficient room for cables, PDU’s as well as airflow.<br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Rack_Server.png","alias":"rack-server"},"453":{"id":453,"title":"Desktop PC","description":" A desktop computer is a personal computer designed for regular use at a single location on or near a desk or table due to its size and power requirements.

A SAN typically is a dedicated network of storage devices not accessible through the local area network (LAN) by other devices, thereby preventing interference of LAN traffic in data transfer.\r\nThe cost and complexity of SANs dropped in the early 2000s to levels allowing wider adoption across both enterprise and small to medium-sized business environments.\r\nA SAN does not provide file abstraction, only block-level operations. However, file systems built on top of SANs do provide file-level access, and are known as shared-disk file systems.\r\nStorage area networks (SANs) are sometimes referred to as network behind the servers and historically developed out of the centralised data storage model, but with its own data network. A SAN is, at its simplest, a dedicated network for data storage. In addition to storing data, SANs allow for the automatic backup of data, and the monitoring of the storage as well as the backup process. A SAN is a combination of hardware and software. It grew out of data-centric mainframe architectures, where clients in a network can connect to several servers that store different types of data. To scale storage capacities as the volumes of data grew, direct-attached storage (DAS) was developed, where disk arrays or just a bunch of disks (JBODs) were attached to servers. In this architecture storage devices can be added to increase storage capacity. However, the server through which the storage devices are accessed is a single point of failure, and a large part of the LAN network bandwidth is used for accessing, storing and backing up data. To solve the single point of failure issue, a direct-attached shared storage architecture was implemented, where several servers could access the same storage device.\r\nDAS was the first network storage system and is still widely implemented where data storage requirements are not very high. Out of it developed the network-attached storage (NAS) architecture, where one or more dedicated file server or storage devices are made available in a LAN. Therefore, the transfer of data, particularly for backup, still takes place over the existing LAN. If more than a terabyte of data was stored at any one time, LAN bandwidth became a bottleneck. Therefore, SANs were developed, where a dedicated storage network was attached to the LAN, and terabytes of data are transferred over a dedicated high speed and bandwidth network. Within the storage network, storage devices are interconnected. Transfer of data between storage devices, such as for backup, happens behind the servers and is meant to be transparent. While in a NAS architecture data is transferred using the TCP and IP protocols over Ethernet, distinct protocols were developed for SANs, such as Fibre Channel, iSCSI, Infiniband. Therefore, SANs often have their own network and storage devices, which have to be bought, installed, and configured. This makes SANs inherently more expensive than NAS architectures.","materialsDescription":"<span style=\"font-weight: bold; \">What is storage virtualization?</span>\r\nA storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers.\r\nA SAN moves storage resources off the common user network and reorganizes them into an independent, high-performance network. This enables each server to access shared storage as if it were a drive directly attached to the server. When a host wants to access a storage device on the SAN, it sends out a block-based access request for the storage device.\r\nA storage area network is typically assembled using three principle components: cabling, host bus adapters (HBAs), and switches attached to storage arrays and servers. Each switch and storage system on the SAN must be interconnected, and the physical interconnections must support bandwidth levels that can adequately handle peak data activities. IT administrators manage storage area networks centrally.\r\nStorage arrays were initially all hard disk drive systems, but are increasingly populated with flash solid-state drives (SSDs).\r\n<span style=\"font-weight: bold; \">What storage area networks are used for?</span>\r\nFibre Channel (FC) SANs have the reputation of being expensive, complex and difficult to manage. Ethernet-based iSCSI has reduced these challenges by encapsulating SCSI commands into IP packets that don't require an FC connection.\r\nThe emergence of iSCSI means that instead of learning, building and managing two networks -- an Ethernet local area network (LAN) for user communication and an FC SAN for storage -- an organization can use its existing knowledge and infrastructure for both LANs and SANs. This is an especially useful approach in small and midsize businesses that may not have the funds or expertise to support a Fibre Channel SAN.\r\nOrganizations use SANs for distributed applications that need fast local network performance. SANs improve the availability of applications through multiple data paths. They can also improve application performance because they enable IT administrators to offload storage functions and segregate networks.\r\nAdditionally, SANs help increase the effectiveness and use of storage because they enable administrators to consolidate resources and deliver tiered storage. SANs also improve data protection and security. Finally, SANs can span multiple sites, which helps companies with their business continuity strategies.\r\n<span style=\"font-weight: bold;\">Types of network protocols</span>\r\nMost storage networks use the SCSI protocol for communication between servers and disk drive devices.[citation needed] A mapping layer to other protocols is used to form a network:\r\n<ul><li>ATA over Ethernet (AoE), mapping of ATA over Ethernet</li><li>Fibre Channel Protocol (FCP), the most prominent one, is a mapping of SCSI over Fibre Channel</li><li>Fibre Channel over Ethernet (FCoE)</li><li>ESCON over Fibre Channel (FICON), used by mainframe computers</li><li>HyperSCSI, mapping of SCSI over Ethernet</li><li>iFCP or SANoIP mapping of FCP over IP</li><li>iSCSI, mapping of SCSI over TCP/IP</li><li>iSCSI Extensions for RDMA (iSER), mapping of iSCSI over InfiniBand</li><li>Network block device, mapping device node requests on UNIX-like systems over stream sockets like TCP/IP</li><li>SCSI RDMA Protocol (SRP), another SCSI implementation for RDMA transports</li></ul>\r\nStorage networks may also be built using SAS and SATA technologies.

Delivering data simply, quickly, and cost-effectively is essential to driving business growth, and the hybrid cloud has emerged as the most efficient way to meet changing business needs. Every IT organization is trying to determine how to modernize with hybrid cloud, and all-flash storage systems are critical on-premises to speed up enterprise applications.

Naturally, due to the amount of power they need, data centers are very price-sensitive to a location’s cost of electricity. The cost is more than centers per kWh, though. Data centers have unique ramp-up needs and reserved capacity demands. The utility’s ability to accommodate these requirements can have a significant impact on cost.

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","alias":"converged-and-hyper-converged-system"},"515":{"id":515,"title":"Tower Server","description":"A tower server is a computer that is built in an upright cabinet that stands alone and that is designed to function as a server. The cabinet is known as a tower, and multiple tower servers can work simultaneously for different tasks and processes. Tower servers are popular owing to the scalability and reliability features since unlimited servers can be added to the existing network largely because of the independent nature of the individual tower servers.\r\nTower servers support most basic applications such as system management, file management, print collaboration, ER applications, distribution and system security.\r\nThere are certain advantages in using tower servers. A tower server is robust and simple in nature. As overall component density is low, easier cooling is possible in tower servers. Possible damage, overheating or downtime can thus be prevented.

Blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. Unlike a rack-mount server, a blade server needs a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form a blade system. Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system as a whole.\r\nIn a standard server-rack configuration, one rack unit or 1U—19 inches (480 mm) wide and 1.75 inches (44 mm) tall—defines the minimum possible size of any equipment. The principal benefit and justification of blade computing relates to lifting this restriction so as to reduce size requirements. The most common computer rack form-factor is 42U high, which limits the number of discrete computer devices directly mountable in a rack to 42 components. Blades do not have this limitation. As of&nbsp; 2014, densities of up to 180 servers per blade system (or 1440 servers per rack) are achievable with blade systems.\r\nEnclosure (or chassis) performs many of the non-core computing services found in most computers. Non-blade systems typically use bulky, hot and space-inefficient components, and may duplicate these across many computers that may or may not perform at capacity. By locating these services in one place and sharing them among the blade computers, the overall utilization becomes higher. The specifics of which services are provided varies by vendor.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power.</span></span> Computers operate over a range of DC voltages, but utilities deliver power as AC, and at higher voltages than required within computers. Converting this current requires one or more power supply units (or PSUs). To ensure that the failure of one power source does not affect the operation of the computer, even entry-level servers may have redundant power supplies, again adding to the bulk and heat output of the design.\r\nThe blade enclosure's power supply provides a single power source for all blades within the enclosure. This single power source may come as a power supply in the enclosure or as a dedicated separate PSU supplying DC to multiple enclosures. This setup reduces the number of PSUs required to provide a resilient power supply.\r\nThe popularity of blade servers, and their own appetite for power, has led to an increase in the number of rack-mountable uninterruptible power supply (or UPS) units, including units targeted specifically towards blade servers (such as the BladeUPS).\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Cooling.</span></span> During operation, electrical and mechanical components produce heat, which a system must dissipate to ensure the proper functioning of its components. Most blade enclosures, like most computing systems, remove heat by using fans.\r\nA frequently underestimated problem when designing high-performance computer systems involves the conflict between the amount of heat a system generates and the ability of its fans to remove the heat. The blade's shared power and cooling means that it does not generate as much heat as traditional servers. Newer blade-enclosures feature variable-speed fans and control logic, or even liquid cooling systems that adjust to meet the system's cooling requirements.\r\nAt the same time, the increased density of blade-server configurations can still result in higher overall demands for cooling with racks populated at over 50% full. This is especially true with early-generation blades. In absolute terms, a fully populated rack of blade servers is likely to require more cooling capacity than a fully populated rack of standard 1U servers. This is because one can fit up to 128 blade servers in the same rack that will only hold 42 1U rack mount servers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Networking.</span></span> Blade servers generally include integrated or optional network interface controllers for Ethernet or host adapters for Fibre Channel storage systems or converged network adapter to combine storage and data via one Fibre Channel over Ethernet interface. In many blades at least one interface is embedded on the motherboard and extra interfaces can be added using mezzanine cards.\r\nA blade enclosure can provide individual external ports to which each network interface on a blade will connect. Alternatively, a blade enclosure can aggregate network interfaces into interconnect devices (such as switches) built into the blade enclosure or in networking blades.\r\nBlade servers function well for specific purposes such as web hosting, virtualization, and cluster computing. Individual blades are typically hot-swappable. As users deal with larger and more diverse workloads, they add more processing power, memory and I/O bandwidth to blade servers. Although blade server technology in theory allows for open, cross-vendor system, most users buy modules, enclosures, racks and management tools from the same vendor.\r\nEventual standardization of the technology might result in more choices for consumers; as of 2009 increasing numbers of third-party software vendors have started to enter this growing field.\r\nBlade servers do not, however, provide the answer to every computing problem. One can view them as a form of productized server-farm that borrows from mainframe packaging, cooling, and power-supply technology. Very large computing tasks may still require server farms of blade servers, and because of blade servers' high power density, can suffer even more acutely from the heating, ventilation, and air conditioning problems that affect large conventional server farms.","materialsDescription":" <span style=\"font-weight: bold;\">What is blade server?</span>\r\nA blade server is a server chassis housing multiple thin, modular electronic circuit boards, known as server blades. Each blade is a server in its own right, often dedicated to a single application. The blades are literally servers on a card, containing processors, memory, integrated network controllers, an optional Fiber Channel host bus adaptor (HBA) and other input/output (IO) ports.\r\nBlade servers allow more processing power in less rack space, simplifying cabling and reducing power consumption. According to a SearchWinSystems.com article on server technology, enterprises moving to blade servers can experience as much as an 85% reduction in cabling for blade installations over conventional 1U or tower servers. With so much less cabling, IT administrators can spend less time managing the infrastructure and more time ensuring high availability.\r\nEach blade typically comes with one or two local ATA or SCSI drives. For additional storage, blade servers can connect to a storage pool facilitated by a network-attached storage (NAS), Fiber Channel, or iSCSI storage-area network (SAN).

Each object typically includes the data itself, a variable amount of metadata, and a globally unique identifier. Object storage can be implemented at multiple levels, including the device level (object-storage device), the system level, and the interface level. In each case, object storage seeks to enable capabilities not addressed by other storage architectures, like interfaces that can be directly programmable by the application, a namespace that can span multiple instances of physical hardware, and data-management functions like data replication and data distribution at object-level granularity.\r\nObject storage systems allow retention of massive amounts of unstructured data. Object storage is used for purposes such as storing photos on Facebook, songs on Spotify, or files in online collaboration services, such as Dropbox.\r\nObject storage is a method of data storage that emerged in the mid-1990s as researchers foresaw that existing storage methods would eventually start to show their limitations in certain scenarios. True to its name, object storage treats data as discrete units, or objects, that are accompanied by metadata and a universally unique identifier (UUID). This unstructured data resides in a flat (as opposed to tiered) address space called a storage pool. Object storage is also known for its compatibility with cloud computing, due to its unlimited scalability and faster data retrieval.\r\nToday, as data comes to underpin everything we do, the adoption of object storage systems has increased.

Instead of breaking files down into blocks to store it on disk using a file system, we deal with whole objects stored over the network. These objects could be an image file, logs, HTML files, or any self-contained blob of bytes. They are unstructured because there is no specific schema or format they need to follow.<br />Object storage took off because it greatly simplified the developer experience. Because the API consists of standard HTTP requests, libraries were quickly developed for most programming languages. Saving a blob of data became as easy as an HTTP PUT request to the object store. Retrieving the file and metadata is a normal GET request. Further, most object storage services can also serve the files publicly to your users, removing the need to maintain a web server to host static assets.\r\nOn top of that, object storage services charge only for the storage space you use (some also charge per HTTP request, and for transfer bandwidth). This is a boon for small developers, who can get world-class storage and hosting of assets at costs that scale with use.\r\n<span style=\"font-weight: bold;\">What are the advantages of object storage?</span>\r\n<ul><li>A simple HTTP API, with clients available for all major operating systems and programming languages</li><li>A cost structure that means you only pay for what you use</li><li>Built-in public serving of static assets means one less server for you to run yourself</li><li>Some object stores offer built-in CDN integration, which caches your assets around the globe to make downloads and page loads faster for your users</li><li>Optional versioning means you can retrieve old versions of objects to recover from accidental overwrites of data</li><li>Object storage services can easily scale from modest needs to really intense use-cases without the developer having to launch more resources or rearchitect to handle the load</li><li>Using an object storage service means you don’t have to maintain hard drives and RAID arrays, as that’s handled by the service provider</li><li>Being able to store chunks of metadata alongside your data blob can further simplify your application architecture</li></ul>\r\n<span style=\"font-weight: bold;\">What are the disadvantages of object storage?</span>\r\n<ul><li>You can’t use object storage services to back a traditional database, due to the high latency of such services</li><li>Object storage doesn’t allow you to alter just a piece of a data blob, you must read and write an entire object at once. This has some performance implications. For instance, on a file system, you can easily append a single line to the end of a log file. On an object storage system, you’d need to retrieve the object, add the new line, and write the entire object back. This makes object storage less ideal for data that changes very frequently</li><li>Operating systems can’t easily mount an object store like a normal disk. There are some clients and adapters to help with this, but in general, using and browsing an object store is not as simple as flipping through directories in a file browser</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/jhghj.png","alias":"object-storage"}},"branches":"Information Technology","companySizes":"More than 2000 Employees","companyUrl":"www.lenovo.com","countryCodes":[],"certifications":[],"isSeller":true,"isSupplier":false,"isVendor":true,"presenterCodeLng":"","seo":{"title":"Lenovo","keywords":"line, computers, notebook, Lenovo, laptops, personal, desktops, world","description":" \r\n<span lang=\"EN\">Lenovo Group Limited is a Chinese multinational corporation that manufactures personal computers and other electronics.

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"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":5259,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/lenovo_logo.png","logo":true,"scheme":false,"title":"All-in-One PC Lenovo ThinkCentre M Series","vendorVerified":0,"rating":"0.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":26,"alias":"all-in-one-pc-lenovo-thinkcentre-m-series","companyTitle":"Lenovo","companyTypes":["vendor"],"companyId":318,"companyAlias":"lenovo","description":"<span style=\"font-weight: bold; \">Productivity enhancers</span>\r\nTackle spreadsheets, multiple presentations, and photo-editing with ease.

By contrast, software is instructions that can be stored and run by hardware. Hardware is so-termed because it is &quot;hard&quot; or rigid with respect to changes or modifications; whereas software is &quot;soft&quot; because it is easy to update or change. Intermediate between software and hardware is &quot;firmware&quot;, 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 &quot;hardness&quot; to &quot;softness&quot; 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 &quot;booting&quot; or &quot;booting up&quot;. 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.

Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large costly minicomputer and mainframes, time-sharing by many people at the same time is not used with personal computers.\r\nInstitutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. While personal computer users may develop their own applications, usually these systems run commercial software, free-of-charge software (&quot;freeware&quot;), which is most often proprietary, or free and open-source software, which is provided in &quot;ready-to-run&quot;, or binary, form. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. Many personal computer users no longer need to write their own programs to make any use of a personal computer, although end-user programming is still feasible. This contrasts with mobile systems, where software is often only available through a manufacturer-supported channel, and end-user program development may be discouraged by lack of support by the manufacturer.\r\nSince the early 1990s, Microsoft operating systems and Intel hardware have dominated much of the personal computer market, first with MS-DOS and then with Microsoft Windows. Alternatives to Microsoft's Windows operating systems occupy a minority share of the industry. These include Apple's macOS and free and open-source Unix-like operating systems.\r\nThe advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people in all countries.\r\n&quot;PC&quot; is an initialism for &quot;personal computer&quot;. The IBM Personal Computer incorporated the designation in its model name. It is sometimes useful to distinguish personal computers of the &quot;IBM Personal Computer&quot; family from personal computers made by other manufacturers. For example, &quot;PC&quot; is used in contrast with &quot;Mac&quot;, an Apple Macintosh computer. Since none of these Apple products were mainframes or time-sharing systems, they were all &quot;personal computers&quot; and not &quot;PC&quot; (brand) computers.","materialsDescription":" <span style=\"font-weight: bold;\">What types of stationary personal computers exist?</span>\r\n<span style=\"font-weight: bold;\">Desktops</span> - refer to the type of stationary PC. From the name it is clear that these are devices that are installed and work on a table and are not transferred during operation. As a rule, representatives of this group are high-performance powerful devices. They consist of a system unit (a rectangular box), to which a monitor, keyboard and mouse are connected.\r\n<span style=\"font-weight: bold;\">Servers</span> - this type of computer has its own specific tasks that it performs remotely or locally in place. The vast majority of servers are quite powerful machines. The appearance of the servers is slightly different from the usual PC - they are mounted in metal racks that look like furniture shelves. The racks themselves are placed in a special room (server room), the necessary temperature regime is necessarily maintained in it.\r\n<span style=\"font-weight: bold;\">Nettops</span> - refer to the type of stationary PC. The system unit is compact in size, usually with low power consumption and noise. Due to the small size, nettops have lower performance, but they fit perfectly into the home environment and do not occupy expensive office space.\r\n<span style=\"font-weight: bold;\">Microcomputers</span> are computers that fit in a miniature enclosure that looks very similar to a flash drive. The microcomputer itself does not have an output device, therefore, through an HDMI connection, it connects to a monitor or TV. Controls, such as a mouse or keyboard, are connected via the built-in USB ports or Bluetooth. Technical specifications depend on the configuration, as with any other PC.\r\n<span style=\"font-weight: bold;\">Monoblocks</span> - refer to the type of stationary PC.

The case consists of a touch screen display - Touchscreen. Their main purpose is surfing the Internet, watching videos, listening to audio, gaming and other applications. The compact dimensions make this group especially popular for travelers. Tablet laptops have a keyboard that either folds up or extends out of a niche under the screen. In tablets, the touchscreen is the input medium. For this group, battery life is important.\r\n<span style=\"font-weight: bold;\">Pocket PCs and smartphones</span> - belong to the type of portable (laptop) PC. Distinctive features are a small size and a large reserve of battery life. The input tool is either a touch screen or a retractable keyboard.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_PC.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":160,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Lenovo_Rack_Servers.png","logo":true,"scheme":false,"title":"Lenovo Rack Servers","vendorVerified":0,"rating":"2.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":26,"alias":"lenovo-rack-servers","companyTitle":"Lenovo","companyTypes":["vendor"],"companyId":318,"companyAlias":"lenovo","description":"Lenovo's single and dual-processor servers provide reliable computing power in a compact package, allowing you to optimize space without sacrificing performance.\r\nEach year, the research company Technology Business Studies conduct a survey of the level of satisfaction among corporate clients and servers that have been working for a year on the x86 server, which ranks first in the world for this indicator.\r\nCorporate users value reliable, production servers that can confidently withstand the company's workload.

Rackmount servers are typically easier for administrators to manage due to proximity, modularity and better cable management. Lockable rack cabinet doors and steel server front panels provide an additional level of physical security. Additionally, rack unit designed servers are better able to keep the server components cool than traditional tower form factor. Industry standard 19-inch racks will allow you to easily expand your business without taking up more valuable floor space.\r\nThere is a lot of thought that needs to go into which size rack server is best bet for your project. Both current requirements and future expansion plans need to be taken into account to ensure your server remains capable in the future.\r\nBoth large and small projects can be built on the 1U server platform. &quot;U&quot; stands for unit, “unit”, and this means thickness: server rack 1U = 1.75 inches or 44 mm wide. A reasonable amount of storage can fit within a 1U, processing power has no limits, and some models even allow up to two PCI-Express cards. Modern computer hardware uses much less power than it ever has in the past, which means less heat generation. Some 1U servers to still produce some acoustic noise, but is nowhere near the level of needing earmuffs like the old days. The only reason to go up in size is for additional expansion options.\r\n2U models allow for multiple &quot;low-profile&quot; PCI-Express cards while keeping a compact form factor and also providing some additional storage space. If the plan is to use multiple full height cards, then 3U or 4U servers should be the focus. The 4U models are very popular and offer flexible options. The 3U models do have limitations on expansion card compatibility and are really only for situations where rack space needs to be absolutely optimized (14x3U servers or 10x4U servers can fit in a 42u rack).","materialsDescription":"<span style=\"font-weight: bold;\">What is a ‘rack unit’?</span>\r\nA rack unit is the designated unit of measurement used when describing or quantifying the vertical space you have available in any equipment rack. One unit is equal to 1.75 inches, or 4.45 centimeters. Any equipment that has the ability to be mounted onto a rack is generally designed in a standard size to fit into many different server rack heights. It’s actually been standardized by the Electronic Industries Alliance (EIA). The most common heights are between 8U to 50U, but customization is also a viable option if you’re working with nonstandard sizes.\r\n<span style=\"font-weight: bold;\">Are there any specific ventilation requirements with server racks?</span>\r\nOver 65% of IT equipment failures are directly attributed to inadequate, poorly maintained, or failed air conditioning in the server room. So yes, proper ventilation is a critical part of maintaining any data center. Some cabinet manufacturers construct side panel ventilation instead of front and back ventilation, but experts say it’s inadequate for rack mount servers. This can be especially dangerous if more than one cabinet is being set up at once. The importance of proper ventilation should not be taken lightly, and you should always opt for front to back ventilation except in network applications where the IT equipment exhausts out the side.\r\n<span style=\"font-weight: bold;\">What is meant by ‘server rack depth’?</span>\r\nServer rack depth is a critical aspect of the ventilation process. Connectworld.net says, “Server cabinet depth is important not only because it has to allow room for the depth of the particular equipment to be rack-mounted (deep servers vs. routers or switches), but also it has to allow sufficient room for cables, PDU’s as well as airflow.<br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Rack_Server.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":4815,"logoURL":"https://old.roi4cio.com/fileadmin/content/1809288690_w640_h640_cid2336127_pid978514602-ec610164_01.jpg","logo":true,"scheme":false,"title":"test product","vendorVerified":0,"rating":"2.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":26,"alias":"test-product","companyTitle":"Lenovo","companyTypes":["vendor"],"companyId":318,"companyAlias":"lenovo","description":"<span style=\"color: rgba(0, 0, 0, 0.87); font-family: 'Open Sans'; font-size: 13px;\">описание</span>","shortDescription":"краткое описание","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":false,"bonus":100,"usingCount":17,"sellingCount":16,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"test product","keywords":"","description":"<span style=\"color: rgba(0, 0, 0, 0.87); font-family: 'Open Sans'; font-size: 13px;\">описание</span>","og:title":"test product","og:description":"<span style=\"color: rgba(0, 0, 0, 0.87); font-family: 'Open Sans'; font-size: 13px;\">описание</span>","og:image":"https://old.roi4cio.com/fileadmin/content/1809288690_w640_h640_cid2336127_pid978514602-ec610164_01.jpg"},"eventUrl":"","translationId":7316,"dealDetails":{"avgPartnerDiscount":5,"dealProtection":0,"avgDealSize":5000,"dealSizeCurrency":"","avgDealClosing":2},"roi":null,"price":null,"bonusForReference":null,"templateData":[],"testingArea":"","categories":[{"id":71,"title":"CRM - Customer Relationship Management","alias":"crm-customer-relationship-management","description":"<span style=\"font-weight: bold;\">Customer service</span> is the provision of service to customers before, during and after a purchase. The perception of success of such interactions is dependent on employees &quot;who can adjust themselves to the personality of the guest&quot;. Customer service concerns the priority an organization assigns to customer service relative to components such as product innovation and pricing. In this sense, an organization that values good customer service may spend more money in training employees than the average organization or may proactively interview customers for feedback.\r\nA <span style=\"font-weight: bold;\">customer support</span> is a range of customer services to assist customers in making cost effective and correct use of a product. It includes assistance in planning, installation, training, trouble shooting, maintenance, upgrading, and disposal of a product. These services even may be done at customer's side where he/she uses the product or service. In this case it is called &quot;at home customer services&quot; or &quot;at home customer support.&quot;\r\nRegarding technology, products such as mobile phones, televisions, computers, software products or other electronic or mechanical goods, it is termed technical support. \r\nCustomer service may be provided by a person (e.g., sales and service representative), or by automated means, such as kiosks, Internet sites, and apps.\r\n<span style=\"font-weight: bold;\">CRM </span>(Customer Relationship Management) is an approach to manage a company's interaction with current and potential customers. It uses data analysis about customers' history with a company to improve business relationships with customers, specifically focusing on customer retention and ultimately driving sales growth.\r\nOne important aspect of the CRM approach is the systems of CRM that compile data from a range of different communication channels, including a company's website, telephone, email, live chat, marketing materials and more recently, social media. Through the CRM approach and the systems used to facilitate it, businesses learn more about their target audiences and how to best cater to their needs.\r\nCRM helps users focus on their organization’s relationships with individual people including customers, service users, colleagues, or suppliers.\r\nWhen people talk about customer relationship management system, they might mean any of three things: \r\n<ul><li><span style=\"font-weight: bold;\">CRM as Technology</span>: This is a technology product, often in the cloud, that teams use to record, report and analyse interactions between the company and users.

You can see everything in one place — a simple, customizable dashboard that can tell you a customer’s previous history with you, the status of their orders, any outstanding customer service issues, and more.\r\nGartner predicts that by 2021, CRM technology will be the single largest revenue area of spending in enterprise software. If your business is going to last, you know that you need a strategy for the future. For forward-thinking businesses, CRM is the framework for that strategy.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are the benefits of CRM?</span></h1>\r\nBy collecting and organising data about customer interactions, making it accessible and actionable for all, and facilitating analysis of that data, CRM offers many benefits and advantages.<br />The benefits and advantages of CRM include:\r\n<ul><li>Enhanced contact management</li><li>Cross-team collaboration</li><li>Heightened productivity</li><li>Empowered sales management</li><li>Accurate sales forecasting</li><li>Reliable reporting</li><li>Improved sales metrics</li><li>Increased customer satisfaction and retention</li><li>Boosted marketing ROI</li><li>Enriched products and services</li></ul>\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are the key features of most popular CRM software programs?</span></h1>\r\nWhile many CRM solutions differ in their specific value propositions — depending on your business size, priority function, or industry type — they usually share some core features. These, in fact, are the foundation of any top CRM software, without which you might end up using an inferior app or an over-rated address book. So, let’s discuss the key features you need to look for when figuring out the best CRM software for your business.\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Contact management</span>. The best CRM solutions aren’t just an address book that only organizes contact details. It manages customer data in a centralized place and gives you a 360-degree view of your customers. You should be able to organize customers’ personal information, demographics, interactions, and transactions in ways that are meaningful to your goals or processes. Moreover, a good contact management feature lets you personalize your outreach campaign. By collecting personal, social, and purchase data, it will help you to segment target audience groups in different ways.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Reporting and dashboards</span>. These features of customer relationship management allow you to use analytics to interpret customer data. Reporting is very useful if you want to consolidate disparate data and churn out insights in different visualizations. This lets you make better decisions or proactively deal with market trends and customer behavioral patterns. The more visual widgets a CRM software has, the better you can present reports. Furthermore, a best customer relationship management software will generate real-time data, making reporting more accurate and timely. Reporting also keeps you tab on sales opportunities like upsell, resell, and cross-sell, especially when integrated with e-commerce platforms.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Lead management</span>. These features let you manage leads all the way to win-loss stage. They pave a clear path to conversion, so you can quickly assess how the business is performing. One of the main three legs that comprises the best client relationship management software (the other two being contact management and reporting), lead management unburdens the sales team from follow-ups, tracking, and repetitive tasks.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Deals and tasks</span>. Deals and tasks are closely associated with leads. Deals are leads at the negotiation stage, so it’s critical to keep a close eye on their associated tasks for a higher chance of conversion.<br />CRM software tools should also let you track both deals and tasks in their respective windows or across the sales stages. Whether you’re viewing a contact or analyzing the sales pipeline, you should be able to immediately check the deal’s tasks and details. Deals and tasks should also have user permissions to protect leaks of sensitive data. Similarly, alerts are critical to tasks so deadlines are met. Notifications are usually sent via email or prominently displayed on the user’s dashboard.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Campaign management</span>. Solid CRM software will integrate this feature to enable marketing processes from outreach concept to A/B testing to deployment and to post analysis. This will allow you to sort campaigns to target segments in your contacts and define deployment strategies. You will also be able to define metrics for various channels, then plow back the insights generated by post-campaign analytics into planning more campaigns.<br />Recurring outreach efforts can also be automated. For instance, you can set to instantly appropriate content to contacts based on their interest or send tiered autoresponders based on campaign feedback.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Email management</span>. By integrating with popular email clients like Gmail and Outlook, CRM solutions can capture email messages and sort important details that can be saved in contacts or synced with leads. They can also track activities like opened emails, forwarded emails, clicked links, and downloaded files. Emails can also be qualified for prospecting.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Social media management. </span>Popular CRM systems feature an integrated social media management where you can view different social media pages from the CRM’s interface. This is a convenient way to post, reply on, and manage all your pages. Likewise, this feature gives you a better perspective on how customers are interacting with your brand. A glean of their likes and dislikes, interests, shares, and public conversations helps you to assess customer biases and preferences. Customers are also increasingly using social media to contact companies; hence, a good CRM should alert you for brand mentions.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Mobile access</span>. With more users accessing apps via mobile devices, many vendors have been prioritizing mobile-first platforms. Emergence Capital Partners study found over 300 mobile-first apps so far and CRM is definitely one their targets. Many CRM solutions have both Android and iOS apps. Mobile access works in two ways to be highly appreciated: accessing data and inputting data while on location. Field sales with the latest sales information on hand may be able to interest prospects better. Conversely, sales reps can quickly update deals across the pipeline even as they come off a client meeting.</li></ul>\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/CRM_-_Customer_Relationship_Management.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}],"suppliedProducts":[],"partnershipProgramme":{"levels":[{"id":139,"level":"Registered"},{"id":140,"level":"Silver"},{"id":141,"level":"Gold"},{"id":142,"level":"Diamond"},{"id":143,"level":"Distributor"}],"partnerDiscounts":{"Registered":"","Silver":"","Gold":"","Diamond":"","Distributor":""},"registeredDiscounts":{"Registered":"","Silver":"","Gold":"","Diamond":"","Distributor":""},"additionalBenefits":[],"salesPlan":{"Registered":"","Silver":"","Gold":"","Diamond":"","Distributor":""},"additionalRequirements":[]}}},"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":""}}
