Explain classification of computers.

Ans: Classification of computers are as:

(i) Micro Computer

(ii) Mini Computer

(iii) Mainframe Computer

The microprocessor gets its name from the fact that its main component, the microprocessor, is located on one integrated circuit component. Micro Computer fit nicely on desktop computer. Many individuals purchase microcomputers for personal use either for their jobs or for other purposes, Micros. Therefore are also known as personal computers. Very large scale integrated (VLSI) technology is used in micro computer and its become very small size and high capacity computer. Laptop computer is a kind of microcomputer.

Mini computer more properly called medium sized computer, slower and less expansive then main frames. They have no special power or environments, so they can be located conveniently through out an organizations facility. They can support a network of user terminals but not as many as mainframe can. They can store and retrieve data from the same types of input and output devices as mainframes, but they have smaller storage capacity1970 almost all minicomputers grew and a 32 bit minicomputer, which has called supermini, was introduced, The supermini has more users working simultaneously on the computer in comparison to previous minicomputers.

Mainframe make up the bulk of computer installations in large organizations at least in the sense that they do more data processing work than any other types of computers, Main frame computers often serve more than one user at a time because they are able to support large network of individuals terminal companies and government agencies, all use mainframe computers, through they often use other types as well most professional programmers work in a mainframe environmental, preparing new programs and maintaining existing ones.
