COMPUTER –THE HARBINGER OF SILENT REVOLUTION
The last two decades are witnessing a computer revolution in which information processing and retrieving are being reliably done at incredible speeds. Today, micro processors can be found in children’s toys, word processors, pocket calculators, industrial robots; home appliances etc., to mention a few of their innumerable uses and there is practically no new machine, instrument, control equipment or information system that does not have a micro processor in it.
The computer is a product of electronic revolution triggered off by the invention of integrated circuits and then the chips produced the third and the fourth generation computers. The race is now on to build the new or the fifth generation computers, machines that exhibit artificial intelligence. The introduction of the Personal Computer (PC) provided a boost to the IT industry in India.
A machine with true artificial intelligence has not been created. Artificial intelligence studies have been focusing too narrowly on ‘problem solving’ as a paradigm for all intelligent behavior. This has led to a paradoxical situation where artificial intelligence specialists have been able to construct sophisticated knowledge based expert systems, but are unable to come to grips with ordinary perceptual and motor behavior involving vision, speech, locomotion, manipulation, language etc. computers at present are smart in some ways but are not intelligent. They “mechanically” work out solutions to problems; they do not use a logical/innovative approach that characterizes humans.
Artificial Intelligence (AI) is the study of ways in which machines can be made to have sufficient creative reasoning power to perform mental task at which, at present human beings are better. Examples of problems that fall under the area of Artificial Intelligence include common sense tasks such as understanding a language, recognizing scenes, designing computer systems, planning scientific expeditions. Expert systems are bridge between human and computer methods and problem solving.
Truly, computer has been the harbinger of a silent revolution. The revolutionary strides made by computer have come without a bang. New developments in the field of computer are taking place everyday and they are also slowly and constantly changing the human life. Man and machine have become communicative and interactive. Men sitting poles apart can communicate directly in their bedrooms. Thus in the spirit of a true revolution computer has transformed the human society.
