Type of computer

There are many type of computer some important type of computer are following:-

1.      PC (Personal Computer):-
                           It is a single user computer system having moderately powerful microprocessor. PCs are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip. At home, the most popular use for personal computers is playing games and surfing the Internet.

2.      Workstation:-

                          It is also a single user computer system, similar to personal computer however has a more powerful microprocessor. Workstations generally come with a large, high-resolution graphics screen, large amount of RAM, inbuilt network support, and a graphical user interface. Most workstations also have mass storage device such as a disk drive, but a special type of workstation, called disk-less workstation, comes without a disk drive.

3.     Mini Computer:-
                         It is a multi-user computer system, capable of supporting hundreds of users simultaneously. A minicomputer is a computer which has all the features of a large size computer, but its size is smaller than those. A minicomputer lies between the mainframe and the microcomputer because its size is smaller than the former one and larger than the latter one. A minicomputer is also called as a mid-range computer. 

4.     Main Frame:-

                                It is a multi-user computer system, capable of supporting hundreds of users simultaneously. Software technology is different from minicomputer. 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 execution of programs.

5.     Supercomputer:-

                                        It is an extremely fast computer, which can execute hundreds of millions of instructions per second. For example, weather forecasting, scientific simulations, (animated) graphics, fluid dynamic calculations, nuclear energy research, electronic design, and analysis of geological data (e.g. in petrochemical prospecting).
