Explain different types of computers.

Microcomputer

Desktop computer, laptop, personal digital assistant (PDA), tablets & smartphones are all types of microcomputers. The microcomputers are widely used & the fastest growing computers. There computers are the cheapest among the other three types of computers. The Micro-computers are specially designed for general usage like entertainment, education and work purpose. Well known manufactures of Micro-computer are Dell, Apple, Samsung, Sony etc.
Desktop computers, Gaming console, sound & Navigation system of a car, Netbooks, Notebooks, PDA's, Tablet PC's Smartphones, Calculators are all type of Micro-Computers.


Minicomputer

Minicomputer, also called mid-range servers, are more powerful computers than micro-computers in terms of processing power and capabilities. Minicomputers are mainly multi user systems Where many users simultaneously work in the larger memories as compared to microcomputers. These are even capable of handling more input-output devices.
       Examples are : PDP-11, VAX, 7500 MAGNUM etc.

Mainframe Computers

Mainframe computers are designed to handle huge volumes of data and information. These can support more than hundred users at same time. These very large and expensive computers have great processing speeds and very large storage capacity and memory as compared to minicomputers. These computers even posses and work with more than one processor at the time. Thus one ca say these are multi-user, multiprocessor systems. For mainframe computers very sophisticated operating systems are needed to control and supervise their operation.
    Examples are : ICL-39, CDC 6600, VAX 8842, IBM 3090/600, IBM 4381.

Supercomputers

Supercomputers are the most powerful computers among digital computers. These consist of several processor running together thereby making them immensely faster and powerful. These computers are capable of handling huge amounts of calculations that are beyond human capabilities. Super computers can perform  billions of instructions per second. Some of the today's super computers have the computing capability equal to that of 40000 micro computers. A Japanese super computer has calculated the value the value of Pi to 16 million decimal places. These are mainly used in application like weather forecasting, nuclear science research, aerodynamic modeling, seismology, metrology etc.
Examples are : CRAY X-MP-14, CDC-205, ETA GF-10, FUJITSU VP-400, NEC SX, PARAM, PACE etc.
