revolution of computers
Answers
Answer:
An invention of miraculous dimensions, computers have revolutionised our lifestyles for the better and continue to do so. In less than fifty years they have influenced practically every field of activity. The Computer Age is our new reality.
No one could have imagined that the initial computing machines would so soon be developed into the highly sophisticated present day computers.
And this stupendous revolution has been carried out by the computer without a shot being fired or a drop of blood being shed.
Computers have taken up key roles in all fields of activity including agriculture, weather forecast scientific research, designing, banks and financial institutions, space research and technology, communication and media, medicine, aviation, railways, traffic control, language learning, literature and entertainment.
A computer is an electronic device that can carry out calculations and process information. Vast amounts of data can be handled effectively and efficiently at a very fast rate.
A computer can virtually carry out any activity but it cannot think at least for now! It thus requires a human operator and a set of detailed instructions, called a program.
The Storage until of a computer is called the memory which can be accessed via an input device- the keyboard. The output and the processed data can be received on a TV screen or in print via a printer.
Computers can vary from the very compact laptops to large mainframe systems and supercomputers. The computer has two parts the hardware, meaning the electronic and mechanical parts, and the software or the programs. Most of the computers are digital and work on the binary system.
Computers have become indispensable in all areas in which they have been introduced. Industries and business houses would virtually collapse if computers were to be suddenly withdrawn.
Right from management, organisation and planning to the actual production, computers are being used at every stage.
Robots, which are nothing but computer-controlled arms and hands, are increasingly in use in assembly lines of many factories. They can efficiently carry out monotonous and hazardous tasks.
Personal robots have also been developed for a variety of uses including assisting handicapped people in becoming independent and self-sustained.
Hazardous tasks like handling dangerous chemicals or metals at high temperatures can be performed with ease by robots under human supervision.
Evil or super-efficient, computers are increasingly making themselves felt as indispensable in homes, school and offices even in a developing country like India.
The silent revolution has been efficiently carried out. Computers are here to stay. It is up to us to use them for the benefit and betterment of mankind.
