A Personal Computer can be defined as a small, relatively inexpensive computer designed for an individual user. Personal Computers are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip. Businesses use personal computers for word processing, accounting, desktop publishing, and for running spreadsheet and database management applications. At home, the most popular use for personal computers is playing games and surfing the Internet.
2. Mini Computer:-
Mini Computer is a midsize multi-processing system capable of supporting up to 250 users simultaneously. These were designed for specific tasks but have now lost popularity due to the advent of PCs. Some of the Popular Minicomputers are given below:- IBM Mid range computers Texas Instrument TI-990
3. Mainframes:-
Mainframe is very large in size and is an expensive computer capable of supporting hundreds or even thousands of users simultaneously. Mainframe executes many programs concurrently and supports many simultaneous executions of programs.
supercomputer:-
A supercomputer is a computer with great speed and memory. This kind of computer can do jobs faster than any other computer of its generation. They are usually thousands of times faster than ordinary personal computers made at that time. The first Atlas was officially commissioned on 7 December 1962, nearly three years after the Cray CDC6600 Supercomputer was introduced, as one of the world's first supercomputers. Seymour Cray is called as father of super computer.
