There are 5 types of Computer.

Personal Computer.

A PC is often defined as a little, relatively inexpensive computer designed for a private user. PCs are supported the microprocessor technology that permits manufacturers to place a whole CPU on one chip.

Businesses use personal computers for data processing, accounting, publication, and for running spreadsheet and management applications. At home, the foremost popular use for private computers is playing games and surfing the web.

Although personal computers are designed as single-user systems, these systems are normally linked together to make a network. In terms of power, nowadays high-end models of the Macintosh and PC offer an equivalent computing power and graphics capability as low-end workstations by Sun Microsystems, Hewlett-Packard, and Dell.


The workstation may be a computer used for engineering applications (CAD/CAM), publication, software development, and other such sorts of applications which require a moderate amount of computing power and comparatively high-quality graphics capabilities.
Workstations generally accompany an outsized, high-resolution graphics screen, an outsized amount of RAM, inbuilt network support, and a graphical interface(GUI). Most workstations even have mass memory device like a disc drive, but a special sort of workstation, called diskless workstation, comes without a disc drive.
There are common operating systems for workstations are UNIX and Windows NT. Like PC, workstations also are single-user computers like PC but are typically linked together to make a (LAN)local-area network, although they will even be used as stand-alone systems.


It is a midsize multi-processing system capable of supporting up to 250 users simultaneously.


The mainframe is extremely large in size and is an upscale computer capable of supporting hundreds or thousands of users simultaneously. Mainframe executes many programs concurrently and supports much simultaneous execution of programs.


Supercomputers are one among the very fastest computers currently available. Supercomputers are very expensive and are employed for specialised applications that need an immense amount of mathematical calculations like(number crunching).
