Generations of Computers

  • First Generation: Vacume Tubes

    First Generation: Vacume Tubes
    [Learnmore at Byte Notes: 1942-1955 Computer Science Learning Platform](http://www.byte-notes.com/five-generations-computers)Developed by scientists Mauchly and Echert. Computers were very large, powered by vacuum tubes, the only available electronic component. Calculated data to the millisecond, but were very slow and relied on machine language. Examples: ENIVAC and UNIVAC-1

  • Second Geneation: Transistors

    Developed by scientists John Barden, William Brattain and William Shockley. Vacuum tubes were replaced by transistors and were much smaller and faster, more reliable and used assembly language. Peripheral drives (printer, magnetic disks, and tapes drives) were used as a faster pace.
    Examples: IBM 7094 series, IBM 1400 series and CDC 164

  • Third Generation: Integrated Circuits

    Third Generation: Integrated Circuits
    Third Generation: Integrated Circuits
    1964- 1971
    These computers used silicon chips that were placed on smaller transistors. Speed and efficiency were increased. These used keyboards, monitors and operation systems. Many applications were able to run simultaneously. Microchips were developed by Jack Kilby
    Examples: IBM 370, IBM System/360, UNIVAC 1108 and UNIVAC AC 9000.

  • Fourth Generation: Microprocessors

    Fourth Generation: Microprocessors
    Fourth Generation: Microprocessors
    !9971-Present
    This generation uses microprocessors which was first developed by developed by Ted Hoff for Intel. With thousands of integrated circuits on one silicon chip the size was drastically reduced. IBM produced the first home computers followed by Apple. The reduced sized made it possible for several computers to be connected in a network. This gave rise to the Internet. Input devices such as the joystick and mouse were developed.
    Examples: Apple

  • Fifth Generation: Artificial Intelligence

    Fifth Generation: Artificial Intelligence
    Fifth Generation: Artificial Intelligence
    Present to Future
    This generation is marked with the computers having the capacity to think on their own. They are presently being developed even though some features like vive recognition have a break through. This generation of computers uses parallel process and supper conductors.
