Workstations have typically been high-end complex instruction set computer (CISC), Explicitly Parallel Instruction Computing (EPIC) or reduced instruction set computer (RISC)-based CPU architectures with high-performance graphics, OS and system architecture. In general, workstations must include a 32-bit or 64-bit multitasking OS, as well as configurations that support high-resolution graphics capabilities and three-dimensional (3D) graphics functionality. The workstation market includes traditional Unix workstations, such as Linux, and workstations running Windows XP/Vista or other advanced OSs.
