2. Based on Size and speed super computer Supercomputer is a broad term for one of the fastest computers currently available in the world. It are very expensive and employed for specialize applications that require immense amounts of mathematical calculations (number crunching). Eg. weather forecasting, scientific design , and analysis of geographical data, satellite communication etc. mainframe computer mainframe was a term originally referring to the cabinet containing the central processor unit or "main frame" of a room-filling stone Age batch machine. The mainframe is a very large and expensive computer capable of supporting hundreds, or even thousands of users simultaneously. The mainframe uses its power to execute many programs concurrently. MiniComputer It is a midsize computer. In the past decade, the large Minicomputers and small mainframe has considered same, however as the distinction between small minicomputers and workstations. A minicomputer is a multiprocessi...

classification of computer
1. Based on working principle /function ot basic types
The computers are classified into the following three types according to their constructions and working.
Digital computer
The digital computers deal with discrete quantities such as beads on an abacus or electrical pulses. The digital computers are the computers that we program and use. These computers accept digital data, process them and produce the result to the user. This type of computer is used in business application. The accuracy of digital computer is quite lower than analog computer.
Analog computer
The analog computer deals with continues physical variables such as electrical voltage or mechanical shaft rotations. The computations with analog computers depends on the relation of information to a measurement of some physical quantity. The accuracy of analog computer is more than digital computer. The analog computers are mostly used for process control applications, equation solution etc.
Hybrid computer
The computer works in the principle of both analog and digital computers. These types of computers are used in the industrial, jet plane etc.
