applications that require a moderate amount of computing power and relatively
high quality graphics capabilities. Workstations generally come with a large,
high-resolution graphics screen, at large amount of RAM, built-in network
support, and a graphical user interface. Most workstations also have a mass
storage device such as a disk drive, but a special type of workstation, called
a diskless workstation, comes without a disk drive. The most common operating
systems for workstations are UNIX and Windows NT. Like personal computers, most
workstations are single-user computers. However, workstations are typically

stand-alone systems.
