A computer is,in a simple sense,a counting machine because it can add, substract, multiply and divide. It is like our brains except that a computer can work much faster and the problems it solves depend on the information given to it by man. It is sometimes called a memory machine since it also keeps the information and provides it when it is needed.
Computer were in fact invented a long time ago. Chinese or japanese merchants have been using a tool to add which is called an 'abacus' or 'cipoa'. These people can add figures by moving the wooden balls of the abacus with their fingers. Another examples of a simple computer is the counting machine found in stores, banks and big offices.
Computer are now used in banks.factories and other industries. More and more of them will be produced to work for big trading companies and industrial businesses. They are being used among other thing to take care of the complex figure,to help correct assignment or examination papers or to send up satelites and rocket and land them on the moon and other place.
Computer do many jobs which cannot be done by human beings but they will never be able to raplace us since our brains are much more complex computer. We have ideas and the ability to invent new thing,where as computes can only function because of the informations we give them. So it's we who determine the use of computers. We control them, they cannot control us.
