Computers are nowadays very widely used in business, industry, science, education, medicine, travel and other fields of human activity. In Latin, “to compute” means “to find the total of” or “to calculate.” A computer gives answers to our problems by taking the information or data (facts) with which it works. It thus solves problems according to our instructions.
A computer can solve mathematical equations, engineering problems of building, and electric power distribution. It counts, lists, compares and rearranges different details on a subject according to detailed programme instructions. In industry, it is used to control different manufacturing (production) operations and machine tools. In hospitals, it is used to arrange and control laboratory and hospital instruments and medicines. It is used to guide and control the movements of ships, airplanes, and spaceships. It is used to design buildings, roads, playgrounds, marketplaces, parks, and so on. Different patterns or designs of cloth and decoration objects can be had on computers.
The use of computers in education started in the 1960s. In the advanced countries, instructional computers are used in two ways to provide a direct presentation of data (facts) or to act as a teacher to test the understanding and knowledge of the student. The computer asks student questions and then gets ready answers. It corrects the answers and then goes on to the more difficult questions.
Now computer typing is getting very popular. In it, moving rays of light from a laser lens are used. The typing is very fast and accurate as well as beautiful and in different forms. Thus, composing on computers has brought about a revolution in high-grade typing and printing.
Interesting use of computers is in music, to compose different new musical tunes and tones from some given sounds stored in them. So a computer can be programmed to produce music in different old and new styles.
The Internet is an international computer network through which computer users all over the world can communicate and exchange information and ideas.” It is now in wide use and en has made the exchange of information in all the arts and sciences easy and fast. For the A social, political & other Topics fastest and instant communication of all kinds of documents and data of every kind, the e-mail is in use within the framework of the Internet.
The memory of the computer is one of its main functions. All kinds of information and facts . can be stored in a computer for further use.

Now, in our country, the record of all the country’s identity cards is computerized. The record of millions of hospital patients, expenditure on defense and different government departments and budget figures, besides other kinds of details, is recorded in computers.
There are advantages (benefits) as well as disadvantages to using computers. They save our time in solving our technical and social problems and in keeping (maintaining) records. They make teaching easy and students feel independent while learning through them. But they also mechanize our life too much. We begin using our minds less and less and begin depending on machines more and more. We spend big amounts of money on educational computer programmes that make teaching a dull affair without the interesting question-answer free classroom atmosphere.
Computers are now. a necessary part of our modern life. We should get the best out of them and learn to put them to the best of use. We should have an independent computer industry producing all sorts of computers and their components (parts).

So much dependence on computers surely degenerates mental and physical power. But the huge advantages of computers far outweigh these few disadvantages. The world is a global village now and we can keep pace with the World through computerization only.
