The Computer The computer has become a part of the media only in recent years. In the 1960s and '70,s computers were mostly used by big companies and businessmen. Very few people could buy a computer to be used at home. In the 1980s and '90s, there was an incredible growth in computer sales. The popularity of the Internet,the World Wide Web and the e-mail have made computers inevitable in the modern world. Internet helps millions of people to communicate with each other quickly and cheaply. Moreover, it enables quick access to knowledge. The first mechanical adding machine was made by Pascal in France, and improved upon by Leibniz in Germany. But it was Charles Babbage of England who made the first calculating machine, called the 'difference engine,' in 1822. Later he designed the even more powerful 'analytical engine' , but could not get it made. Its basic design is remarkably similar to the modern electronic computer. The processing of data with mechanical machines started with the 1890 U.S. census. It was done with punched cards and tabulating machines, designed and made by Herman Hollerith. The first electronic computers were made in the late forties in the USA ,Germany and England.Electronic Numeric Integrated and Calculator (ENIAC), made in the USA, is the best known among these first generation computers. The invention of the transistor in 1948 led to the making of the second generation machines in the fifties. Then, came the third generation in the sixties, with the machines using integrated circuits. The invention of the microprocessor in 1971 brought the fourth generation. With each new generation, computers have become more powerful , more reliable, smaller in size and cheaper. The fifth generation, promised by the Japanese,is yet to come.
