classify computers according to their speed
Answers
According to size ⢠Supercomputers ⢠Mainframe Computers ⢠Minicomputers ⢠Workstations ⢠Microcomputers, or Personal Computers Supercomputers : are widely used in scientific applications such as aerodynamic design simulation, processing of geological data. ⢠Supercomputers are the most powerful computers. They are used for problems requiring complex calculations. ⢠Because of their size and expense, supercomputers are relatively rare. ⢠Supercomputers are used by universities, government agencies, and large businesses. Mainframe Computers: are usually slower, less powerful and less expensive than supercomputers. A technique that allows many people at terminals, to access the same computer at one time is called time sharing. Mainframes are used by banks and many business to update inventory etc. ⢠Mainframe computers can support hundreds or thousands of users, handling massive amounts of input, output, and storage. ⢠Mainframe computers are used in large organizations where many users need access to shared data and programs. ⢠Mainframes are also used as e-commerce servers, handling transactions over the Internet. Minicomputers: are smaller than mainframe, general purpose computers, and give computing power without adding the prohibitive expenses associated with larger systems. It is generally easier to use. ⢠Minicomputers usually have multiple terminals. ⢠Minicomputers may be used as network servers and Internet servers. Workstations ⢠Workstations are powerful single-user computers. ⢠Workstations are used for tasks that require a great deal of number-crunching power, such as product design and computer animation. â¢
Answer:
Classification of Computers According to Size
Therefore very large computers used are called Super Computers. These computers are extremely expensive and the speed is measured in billions of instructions per seconds. The most expensive, largest and the most quickest or speedy computer are called mainframe computers.
