classification of computer

The computer systems can be classified on the following basis #1..Mini computers : These computers came into the market in mid 1960s and were sold at a much cheaper price than the main frames, they were actually designed for control, instrumentation, human interaction, and communication switching as distinct from calculation and record keeping, later they became very popular for personal uses with evolution.

2..Micro computers : A microcomputer is a small, relatively inexpensive computer with a microprocessor as its CPU. It includes a microprocessor, memory, and minimal I/O circuitry mounted on a single printed circuit board. The previous to these computers, mainframes and minicomputers, were comparatively much larger, hard to maintain and more expensive. They actually formed the foundation for present day microcomputers and smart gadgets that we use in day to day life.

3.... Supercomputers: The most efficient computers in terms of processing data and performance are supercomputers. These computers are used for research and exploratory purposes. Supercomputers are exceedingly large and highly expensive. It can only fit in large, air-conditioned spaces. 4. Workstation:The workstation is a computer used for engineering applications (CAD/CAM), desktop publishing, software development, and other such types of applications which require a moderate amount of computing power and relatively high-quality graphics capabilities

5. Personal Computer: A PC can be defined as a small, relatively inexpensive computer designed for an individual user. PCs 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. 6. Laptop Computer As their name suggests, laptops are computers that look like sleek briefcases. Additionally, they can serve as desktop computers and run on both an internal battery and a wall outlet. 7.Server Micro Computer Despite looking like a computer, the server microcomputer possesses various additional characteristics that allow it to transfer data to another interface over several networks, including LANs and wide-area networks (WANs). The Apache HTTP Server manages all web pages, while the Mail server sends and receives emails. 8. Network Computer: A network computer is an inexpensive personal computer designed for a centrally-managed network — that is, data are stored and updated on a network server — and lacks a disk drive, CD-ROM drive or expansion slots. A network computer depends on network servers for processing power and data storage
