ESSAY ON COMPUTER AND IT'S USES

A COMPUTER is "defined as an electronic machine which accepts data as input, processes and finally gives information as output." A Computer is the single & greatest invention. The computer is essentially a machine that enables humans to complete tasks that may be time consuming or very repetitive in nature. Thus, it achieves by imitating human thought processes. In much, the same way, that humans think using pathways in their brains that conduct minute electrical currents, computers too use tiny electrical circuits, which tell it what to do. The difference being that computers do this at incredible speeds.

In this modern age, man has grown to be heavily dependent on computers to carry out all kinds of jobs that were done manually before. In banking, for example, computers allow for millions of transactions to be carried out involving large sums of money , which would otherwise require thousands of bank tellers. Computers do the job in a much shorter time and practically free of any errors. Computers are responsible for air traffic control and the running of trains to ensure that travel is made as smooth as possible. In factories now-a-days, computers operate mechanical devices that produce goods we require for everyday living, in such quantities that would be otherwise impossible to achieve, if these factories were run by humans alone.

Perhaps the greatest advancements have been made in the field of communications. All of us are by now familiar with the "Internet." The internet is "a collection of computer systems and individual terminals linked up worldwide through telephone lines and other channels." It offers a cheaper alternative to communicating with people within a country and internationally through computers. It has also been described as an immense pool of knowledge just waiting for applications it has given rise to a new means for countries to carry on trade with each other through "E-Commerce".  It must however be kept in mind that as useful as computers are. They are not capable of independent thought and still require human input. In recent times scientists have developed "Artificial Intelligence" (AI in short) in computers that may enable them to function independently of man in the future.

Answer 2

Computer is an electronic machine that process the data given by us.Computer performs by instructions called programs.Computer is consists of about 3 parts.i.e.Input unit,central processing unit,output unit.

■ Input unit;

The devices which we use to input information are come under input unit.eg.keyboard,mouse,etc

■central processing unit;

It performs the main function.

■out put devices;

The devices which gives output are called output devices.

Computer is used to store data,information, memories,etc.
