Workstation is a computer used for engineering applications (CAD/CAM), desktop publishing, software
development, and other such types of applications which require a moderate amount of computing power and
relatively high quality graphics capabilities.
Workstations generally come with a large, high-resolution graphics screen, large amount of RAM, inbuilt network
support, and a graphical user interface. Most workstations also have mass storage device such as a disk drive, but
a special type of workstation, called diskless workstation, comes without a disk drive.
Common operating systems for workstations are UNIX and Windows NT. Like PC, workstations are also singleuser computers like PC but are typically linked together to form a local-area network, although they can also be
used as stand-alone systems.
It is a midsize multi-processing system capable of supporting up to 250 users simultaneously.
Mainframe is very large in size and is an expensive computer capable of supporting hundreds or even thousands of
users simultaneously. Mainframe executes many programs concurrently and supports many simultaneous
execution of programs.
Supercomputers are one of the fastest computers currently available. Supercomputers are very expensive and are
employed for specialized applications that require immense amount of mathematical calculations (number
For example, weather forecasting, scientific simulations, (animated) graphics, fluid dynamic calculations, nuclear
energy research, electronic design, and analysis of geological data (e.g. in petrochemical prospecting).
