Essay for Kids on Various Types of Computers
Answers
:
They range from micro-computers to supercomputers. There has been a tremendous and significant development in computer technology since the first commercial computer became available in 1950s.
1. Supercomputers:
Supercomputers are the fastest and the largest computers available today. They have large memories and high processing speeds so that they can process nearly a billion transactions per second and nearly a trillion arithmetic operations in the same time. While conventional computers have a single processor which processes one instruction at a time, supercomputers, have multiple processors that process multiple instructions at a time.
The process in known as “parallel processing” (It is argued that a supercomputer can do in a single second what would take a person punching one calculation per second into a hand-held calculator 24 hours a day, 365 days a year, nearly 31,709 years to do).
2. Mainframe Computer:
:
A mainframe is a large, general purpose computer which generally serves 100 or more end users. They have a large memory and excellent processing capabilities and often serve as a central computing system for major corporations and government agencies®. They are ideal for transaction processing, financial application, payroll calculations, airline reservations and so on.
3. Microcomputers:
Also known as personal computers (PCs), microcomputers have revolutionized the computer technology by making computers compact, powerful and versatile machines. These personal computers are available in the form of desk-tops, laptops and note books. They generally serve a single end-user.
The heart of a microcomputer is the microprocessor, a device that integrates the computer’s memory, logic and control on a single chip. Because of their flexibility, micro computers simplify many aspects of management. They may interact with the mainframe to give executives access to corporate data bases.
