(1) A term traditionally used to describe a high-end, high-performance assembly of equipment, including extensive computer graphics capability, as an interactive console for performing a specialized function such as computer-aided design, computer animation, or complex data analysis. Typically, the workstation includes enough computing power and data storage capacity to operate free-standing from any other computer, although workstations are often networked to larger systems for data archives, communication with other workstations, etc. As the technology of personal computers has improved, they have taken on functions previously handled on workstations. (2) Any assembly of computer equipment designed to support the full range of work of an individual.
