Computers are also classified according to their purpose in two different classes. The two classes are as follows:
1. General purpose computer:
General purpose computers are designed to solve a large variety of problems. That is they can be given different programmes to solve different types of problems. General purpose computers can process business data as readily as they process complex mathematical formulas. General purpose computers can store large amounts of data and the programmes necessary to process them.
Because general purpose computers are so versatile, most businesses today use them most digital computers are general purpose computers and it is mainly such computers that are used in business and commercial data processing.
2. Special purpose computers:
Special purpose computers are designed to solve a specific problem; the computer programme for solving the problem is built right into them. computer. Special purpose computers have many features of general purpose computers but are designed to handle specific problems and are not applied to other computerized activities. For example, special purpose computers may be designed to process only numeric data or to completely control automated manufacturing processes. Most analog computers are special purpose computers.
Special purpose computers are often used as training simulators. A simulator is a computer-controlled device for training people under simulators.
The aircraft industry uses simulators to train pilots and flight crews in completely equipped computers-controlled cockpits. The computer creates a variety of flight conditions and monitors trainees’ reactions to them. After getting passing marks on the simulator, trainees move on to actual aircraft. Simulators cut training costs.
