<ul><li><p>GENERATION OF COMPUTERSAvinash Ranjan</p></li><li><p>FIRST GENERATION(1940-1956)The first generation computers used vacuum tubes.It was invented by Lee De Forest.They came into existence in 1940.They were very huge.It consumed a lot of electricity</p></li><li><p>VACUUM TUBES</p></li><li><p>SECOND GENERATION(1956-1963)Transistors were used in second generation computers.They were invented by William Shockley.They came into existence in 1956.The transistor was far superior to vacuum tubes.This helped the computers to become smaller, faster and cheaper.</p></li><li><p>TRANSISTOR</p></li><li><p>THIRD GENERATION(1964-1971)Integrated circuits were used in third generation computers.They were invented by Jack Kilby and Robert Noyce.They came into existence in 1964.They were very small in size.Production cost was very cheap.</p></li><li><p>INTEGRATED CIRCUITS</p></li><li><p>FOURTH GENERATION(1971-PRESENT)The microprocessor brought the fourth generation of computers.They came into existence in 1971.They were invented by Ted Hoff.Power consumption was very less.Thousands of integrated circuits were built to form a single chip.</p></li><li><p>MICROPROCESSORS</p></li><li><p>FIFTH GENERATION(PRESENT AND BEYOND)Fifth generation computers are based on artificial intelligence.They are still in development.The use of parallel processing and superconductors is helping to make artificial intelligence a reality.</p></li><li><p>THANK YOU Avinash Ranjan</p></li></ul>
