  • 1st generation of the computer

    The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently.

  • 2nd generation of the computer

    A second-generation computer, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic-core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation computer.

  • 3rd generation of the computer

    Third-generation computers used integrated circuits in place of transistors. With the use of integrated circuits, these computers became reliable, generated less heat, were small in size, fast, very less maintenance, and were inexpensive. It was developed in 1958 by Robert Noyce and Jack Kilby.

  • 4th generation of the computer

    Fourth Generation Computers. After third-generation computers, which mostly utilized microprocessors, fourth-generation computers were released in 1972. VLSI technology, or Very Large Scale Integrated (VLSI) circuits, was employed in these computers. As a result, they were dubbed microprocessors.
