First generation

History of Computer Generations

By Javier Calderón Baez

  • First Computer Generation

    First Computer Generation
    Vacuum tube technology
    Unreliable
    Supported machine language only
    Very costly
    Generated lot of heat
    Slow input and output devices
    Huge size
    Need of A.C.

  • Second Computer Generation

    Second Computer Generation
    Use of transistors Reliable in comparison to first generation computers Smaller size as compared to first generation computers Generated less heat as compared to first generation computers Consumed less electricity as compared to first generation computers Faster than first generation computers Still very costly A.C. needed

  • Third Computer Generation

    Third Computer Generation
    IC used
    More reliable in comparison to previous two generations
    Smaller size
    Generated less heat
    Faster
    Lesser maintenance
    Still costly
    A.C needed
    Consumed lesser electricity

  • Fourth Computer Generation

    Fourth Computer Generation
    VLSI technology used
    Very cheap
    Portable and reliable
    Use of PC's
    Very small size
    Pipeline processing
    No A.C. needed
    Concept of internet was introduced
    Great developments in the fields of networks
    Computers became easily available

  • Fifth Computer Generation

    Fifth Computer Generation
    ULSI technology Development of true artificial intelligence Development of Natural language processing Advancement in Parallel Processing Advancement in Superconductor technology More user friendly interfaces with multimedia features
