Born in the USA in 1937 Computer has come of age. For years it was monopolized by BMC (International Business Machine Corporation) USA. Justifying its name it was originally a calculating gadget. As it grew in age the electric circuits and transistors underwent sophisticated formations. The calculators were left for small manufacturers. They dwarfed themselves to the size of a playing card or even smaller to fit in the pockets and purses of students and businessmen.
End of the century saw the sixth generation of computers performing different functions. They store information as the human brain does. Like human brain they manipulate, compare and come to decisions. While human brain may take a long time a computer meant for the purpose comes to the conclusion within seconds. The modern computer is billions of times faster and decisive than human brain.
We have men trained and specialized in different trades. So have we computers meant for different purposes. One may approach the astrological Computer; feed it with the qualities and qualifications of the boy and the girl. Within a second it will let one know if the marriage would be successful or not. There are computers that would compose hundreds of pages of a book in a day. Big industrialists and business firms keep their accounts and secrets in computers. Super computers are installed in banks and would allow a customer to draw money from any branch in the city or region.
The more sophisticated a man is the more prone is he to diseases. It is true about computers too. In the beginning of the Eighties Pakistan interfered with the border communication system of Indian Forces manned by computers. The Indian soldiers received strange orders and were confused. The USA communication system was infested by computer virus in later eighties. Someone fed one of the computers with strange things that disturbed the whole system and destroyed the labour of billions of man hours.
India, in many cities, has installed computerized railway reservation system. In many cities almost all the railway regions, stations have been interlinked. In 1989 India installed a Super Computer acquired from USA to interlink all the odd 500 district places of the country with Delhi. Let us be cautious about the virus. By 1988 the fastest Super Computer was manufactured by a US firm. It produced 2.7 billion operations per second. By the end of 1990 HNSX a combination of a Japanese firm and one of the USA delivered another super computer ‘Crey3’ which performs 16 billion operations per second. USA has an eye on a super computer it expects to bring about before the end of the century. It is aimed at a capability of producing a trillion (one thousand billion) operations per second.
Let us wish and hope they are not infested by virus and are not used for destructive purposes.
