The personal computer is although the most popular computer system, there are other computer systems too which is categorized on the basis of cost size and performance.
Personal computer or microcomputers:
Microcomputers is also known as personal computer. Most popular form of the computer in use today is probably the PC. The PC can be used for various applications and in fact, there are millions of PC already in use by individuals and organizations. The size of microcomputer is reduced to small pocket, calculator, laptop and network. It can communicate with different computer by using modem or LAN card. It can perform a diverse range of functions, from keeping track of household accounts to keeping records of the stores of a large manufacturing company. The most widespread is the IBM PC, based on microprocessors from Intel corporation, PS/2 and Apple’s Macintosh.
Minicomputers
It is medium in size which means it is bigger than microcomputer and smaller than mainframe. It can vary in size form a small desktop model to the size of a small filing cabinet. It resembles mainframe computers but they are comparatively small and less expensive. While most PCs are oriented towards single users. Mini systems are usually designed to simultaneously handle the needs of multiple users i.e more than one person use a mini computer at the same time. Today's computer vendors include IBM,Digital/Compaq and Hewlett Packard. IBM’s As/400 has probably been the most popular minicomputer of all time.
Mainframe computer
A mainframe is another form of a computer system that is generally more powerful than a typical mini system. Mainframes themselves may vary widely in cost and capability. They are used in large organizations for large scale jobs. It has faster processing unit, large storage capacity than typical mini computer. Currently IBM mainframe are dominant in the market with Hitachi, Amdahl and Fujitsu also producing machines. Prices start at several hundred thousand dollars.
Super computer
These systems are the largest fastest an the most expensive computer in the world. They are even faster than the mainframe(i.e 200 times faster). They are designed to process complex scientific jobs , bio-medical research, weather forecasting chemical analysis in laboratory and defense applications NEC’s earth simulator in JAPAN is how the worlds faster super computer.
