Introduction to Digital Computer
There are four types of digital computer….
- Super Computer
- Mainframe Computer
- Mini Computer
- Micro Compute
A Supercomputer is used for super complex task such as Weather Forecasting, Nuclear Simulation etc. The first Supercomputer is introduced in 1976. CRAY 1 is first Supercomputer.
Mainframe computers are computers used primarily by large organizations for critical applications, bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and transaction processing.
A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board.
A minicomputer, a term no longer much used, is a computer of a size intermediate between a microcomputer and a mainframe.
