Best Answer

First generation (1940-1956) Vaccum Tubes

Second Generation(1956-1963)Transistors

Third Generation(1964-1971)Integrated circuits

Fourth Generation(1971-present)Microprocessors

We already know about some of the early computers - ENIAC , EDVAC , EDSAC , UNIVAC I and IBM . These machines and others of their time used thousands of vacuum tubes . A vacuum tube was a fragile glass device , which used filaments as a source of electronics and could control and amplify electronic signals . It was the only high-speed electronic switching device available in those days . These vacuum tube computers could perform computations in milliseconds and were referred to as first generation computers.

  • First Generation of the computers was developed by two scientists MAUCHLY and ECHERT in the year 1947.These computer were consist of Vacuum tube and they are not much reliable.
  • Second Generation of computers was developed by John Bardeen, William Brattain and William Shockley in the year 1955.These computer were consist of transistors but they were more reliable then previous.
  • Third Generation of computers used INTEGRATED circuits.Jack Kilby developed the concept of IC in 1959.These computer were much more reliable.
  • Fourth Generation used Microprocessor.Ted Hoffproduced the first microprocessor in 1971 for INTEL.More powerful and reliable and smaller in size.
