Today, supercomputers are typically one-of-a-kind custom designs produced by

"traditional" companies such asCray, IBM and Hewlett-Packard, who had purchased

many of the 1980s companies to gain their experience. As of May 2010, the CrayJaguaris the fastest supercomputer in theworld.

Mainframe Computer

A mainframe (also known as "big iron") is a high-performance computer used for large-

scale computing purposes that require greater availability and security than a smaller-scale machine can offer. Historically, mainframes have been associated with centralized

rather than distributed computing. IBM emphasizes that their mainframes can be used to

serve distributed users and smaller servers in a computing network.

Workstation

A workstation is a high-end microcomputerdesigned for technical or scientific

applications. Intended primarily to be used by one person at a time, they are commonlyconnected to a local area networkand run multi-useroperating systems. The term

workstation has also been used to refer to a mainframe computerterminal or a PC

connected to a network.

Historically, workstations had offered higher performance thanpersonal computers,especially with respect toCPU and graphics, memory capacity and multitasking

capability. They are optimized for the visualization and manipulation of different types of

complex data such as 3D mechanical design, engineering simulation (e.g.computationalfluid dynamics), animation and rendering of images, and mathematical plots. Consoles

consist of a high resolution display, a keyboard and a mouse at a minimum, but also offer

multiple displays, graphics tablets, 3D mice (devices for manipulating and navigating 3Dobjects and scenes), etc. Workstations are the first segment of the computer market to

present advanced accessories and collaboration tools.

Presently, the workstation market is highly commoditized and is dominated by large PC

vendors, such as Dell and HP, sellingMicrosoft Windows/Linux running on IntelXeon/AMDOpteron. Alternative UNIX based platforms are provided by Apple Inc., Sun

Microsystems, and SGI.

Laptop

A laptop is apersonal computerdesigned formobile use[1] . A laptop integrates most ofthe typical componentsof a desktop computer, including a display, a keyboard, a pointing

device (a touchpad, also known as a trackpad, and/or apointing stick) and speakers into a

single unit. A laptop is powered by mains electricity via an AC adapter, and can be used

away from an outlet using a rechargeable battery. A laptop battery in new conditiontypically stores enough energy to run the laptop for three to five hours, depending on the

computer usage, configuration and power management settings. When the laptop is

plugged into the mains, the battery charges, whether or not the computer is running.

Personal computer

A personal computer (PC) is any general-purpose computerwhose size, capabilities,and original sales price make it useful for individuals, and which is intended to be

operated directly by an end user with no intervening computer operator.

A personal computer may be a desktop computer, a laptop, a tablet PC, or a handheld PC(also called a palmtop). The most common microprocessorsin personal computers are

x86-compatible CPUs. Software applications for personal computers include word

processing,spreadsheets, databases, Web browsers and e-mail clients, games, and myriad

personal productivity and special-purpose software applications. Modern personalcomputers often have connections to theInternet, allowing access to theWorld Wide

Web and a wide range of other resources.

A PC may be used at home or in an office. Personal computers may be connected to a

local area network(LAN), either by a cable or a wireless connection.

While early PC owners usually had to write their own programs to do anything useful

with the machines, today's users have access to a wide range of commercial and non-

commercial software, which is provided in ready-to-run or ready-to-compile form. Sincethe 1980s,Microsoft and Intel have dominated much of the personal computer market,

first with MS-DOS and then with the Wintel platform.
