  • First generation of Computer

    First generation of Computer
    The first generation of a computer was called the vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for circuitry. Although superseded by the second-generation computers, vacuum-tube computers continued to be built into the 1960s. J.P.Eckert and J.W. Mauchy invented the first successful first-generation computer between 1942-46

  • Second Generation of computer

    Second Generation of computer
    In this generation, transistors were used that were cheaper, consumed less power, more compact in size, more reliable and faster than the first generation machines made of vacuum tubes. In this generation, magnetic cores were used as the primary memory and magnetic tape and magnetic disks as secondary storage devices.
    The people who invented the second generation computer were John Bardeen , William B. Shockley, and Walter H

  • Third Generation computer

    Third Generation computer
    The third generation of computer is marked by the use of Integrated Circuits instead of transistors. A single circuit has many transistors, resistors and capacitors along with the associated circuitry. The circuit was invented by Jack Kilby. This development made computers smaller in size. Robert Noyce had developed the third generation computer.

  • Fourth Generation of computer

    Fourth Generation of computer
    The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI)circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation. In 1971, Intel released the 4004 microprocessor and the Fourth Generation of computers had begun.

  • Fifth Generation computer

    Fifth Generation computer
    In the fifth generation, VLSI technology became ULSI (Ultra Large Scale Integration) technology, resulting in the production of microprocessor chips having ten million electronic components. This generation is based on corresponding processing hardware and AI (Artificial Intelligence) software. Japan's Ministry of International Trade and Industry invented the fifth generation of computer in 1982.
