First generation (1940-1956) Vaccum Tubes
Third Generation(1964-1971)Integrated circuits
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.
