system unit are combined into a single device. 

Workstation Computer

It was introduced in early 1980. It is more expensive and

powerful personal computer. It is used for calculations and

graphics work. A workstation can tackle the tasks that require a

artists and archive. Architecture uses a workstation to view

and create maps. A graphic artist uses a workstation to create

computer-animated special effects for full-length motion
