This is an age of science and it has changed everything under the sun. It has brought a revolution everywhere. Even we can call it the age of inventions. Besides other wonderful inventions computer is the latest and the greatest invention of the modern times. Now computers , computers every where.
Computers are referred to in the press on the radio and television. They appear in films and books and now have invaded our Govt. policies too. It is true that f we miss the catch up with our environment economic, social and cultural and so we should permit computerization at national level.
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 computerization over a short as well as long period of time?
A computer was created for computing fast a purely mathematical function. Today there are used to forecast the weather to operate machines to cut steel to size and even to guide a space craft to the moon. Computers help to trace criminals are used in the air lines. The whole world of air lines fundtions efficiently with its help. Hotels make use of them from managerial capacities to kitchen and companies use them for accounting invoicing etc.
Thus a computer is a data processing device which acts upon data coming to it in a shapes and sizes. It deals with the science of information processing, invoicing, recording, manipulating, and retrieving information. Computers are electronic devices. 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 will be a premium. The micro processor as the central leader will lead the industry. It could easily be concluded that in the long run. Computerization on a large scale would become essentially a matter of survival.
Hence it is essential to bring an awareness of computers among the common people. So that they could use it in a better way and take full advantage of this wonderful invention.
