- is a multi user computers that lies in the middle range of the computing spectrum, in between the largest mainframe computer and the smallest single user systems ( microcomputer )

- was created to distinguish the traditional large institutional computer intended to service multiple users from the smaller single user machines.

According to Data handled
1. Analogue Computer

Types of Computer
- are the most common type of computer. The term ‘microcomputer’ was introduced with a single chip of
