The Computers very tremendously in size, from desk top models to huge machines occupying an entire room or even more, but they all contain the some components parts which came under the heading of machines is called a computer configuration . Software refers to the programmed that instruct the machine.

There are two basic types of computer, digital and analogue. Both type are highly complex systems of electrical circuits to carry out complicated, calculations to solve difficult problems. They hybrid is a third type which consists of a combination of the other two. The digital computer is basically a counting machine. A small digital computer is able to multiply, divide, subtract and add all at high speed, which are electrically powered and operated by hand like typewriters. Large digital computer receive data and information on punched-cards or magnetic tape. This data is read by the unit called the reader, which convert it into a form usable by computer.
The analogue computers are specially designed to deal with particular problems such as guiding moon rockets.
Today the computers permeates the whole world of work in homes, in factories in schools, in hospitals, in offices, in hotels etc..... because it is an enormously flexible tool that can be used in wide variety of ways, depending on needs and available resources.

The computer are here to stay in the modern world and the more we understand them, the better will be the days ahead of us. For with their help and one skills, the present can be utilized to predict what is sure to and be well prepared to meet the challenge....
