Short essay for kids on Computers Today. Computers are being talked about everywhere, in the press, on the radio and the television. They appear in films and books and have now invaded all walks of life.
It is necessary that we should not miss to catch up with the latest environmental, economic, social and cultural progress, and so we should encourage computerisation at all levels.
If a developing nation has to invest in this technology, we must have a good set of reasons. Let us try to answer basic questions like (1) What is a computer? (2) What can it do? (3) How can one communicate with it? (4) What are the implications of computerisation over a short as well as long period of time?
A computer was created for computing fast—a purely mathematical function. Today they are used to forecast the weather, to operate machines, to cut steel to size and even to guide a spacecraft to the moon. Computers help to trace criminals and are used in the airlines industry. The whole world of airlines functions efficiently with its help. Hotels make use of them from managerial functions to kitchen operations, and companies use them for accounting, invoicing etc.
Thus, a computer is a data processing device which acts upon data coming to it in all shapes and sizes. It deals with the science of information processing, invoicing, recording, manipulating and retrieving information. Computers are electronic devices in which all information stored as patterns of electrical pulses. A computer has to be programmed as per the requirement, either to guide a missile or to write poetry.
In the years to come, energy-efficient technologies be at a premium; the microprocessor as the key machine will lead the industry. It could easily be concluded that in the long run, computerisation on a large scale will essentially become a matter of survival.
Hence, it is really important to bring an awareness of computers among the common people.
