Computer is the latest miracle that has ushered in a revolution in the application of science for the benefit of mankind. It is like a super electronic brain doing all types of difficult calculations, keeping records and storing data for mankind. Its main features are speed, accuracy and ability to store large amounts of data. It is an appliance which can do a job in seconds that would normally take days for hundreds of people to accomplish.
The modern world is undoubtedly a world of computers.Age old system of keeping records in voluminous registers and files is gradually making way for computer based data processing.It is used in schools, colleges, offices, banks, airlines, shops, laboratories, hospitals and libraries. Computer based telecommunication network can link-up any part of the world at any time. Robots have replaced manual labour in factories. In the field of medical diagnosis and printing technology computerised machines are doing wonders. The space flights would not have been possible without the application of computer science.
Computers dominate every sphere of man’s life. Its presence has been felt in railways, airlines, industries, commercial establishments, banks and telecommunications. Typewriters have made room for computerised word processors.
Even though computers yield greater productivity, they can replace human labour and cause unemployment. While mankind should reap the benefits of computerization, they should not allow it to deteriorate the employment situation.
