GENERACIONES DE LA COMPUTADORA

By gina mertin

  • FIRST GENERATION

    FIRST GENERATION
    In this generation there was a great ignorance of the capabilities of computers.These machines had the following characteristics:
    • They used vacuum tubes to process information.
    • They used punched cards to enter data and programs.
    • They used magnetic cilynders to store information and internal instrucctions.
    • They were extremely large, they used a lot of electricity, they generated a lot of heat and they were slow.
    • The binary system began to be used to represent the data.

  • SECOND GENERATION

    SECOND GENERATION
    In this generation, computers are reduced in size. The Characteristics of this generation:
    • They used transistors to process information.
    • Transistors were faster, smaller and more reliable than vacuum tubes, They used small magnetic rings to store information and instructions. amount of heat and they were extremely slow.
    • Used in airline reservation , air traffic control and general purpose simulations.
    • The Navy of the United States develops the first flight simulator, "Whirlwind I".

  • THIRD GENERATION

    THIRD GENERATION
    The third generation of computers emerged with the development of integrated circuits (silicon wafer) in which thousands of electronic components are placed in a miniature integration.
    • Integrated circuits were developed to process information.
    •Chips were developed to store and process information. A chip is a piece of silicon that contains miniature electronic components called semiconductors.
    • Integrated circuits remember the data, since they store the information as electrical charges.

  • FOURTH GENERATION

    FOURTH GENERATION
    They appear the microprocessors that is a great advance of the microelectronics, they are integrated circuits of high density and with an impressive speed. The microprocessor was developed. More circuits are placed inside . a "chip". A simple "chip" currently contains the control unit and the arithmetic / logic unit. the primary memory, is operated by other "chips". The memory of magnetic rings is replaced by the memory of silicon. The microcomputers are developed, that is, personal and PC.

  • FIFTH GENERATION

    FIFTH GENERATION
    International competition arises for the dominance of the computer market, the ability to communicate with the computer in a more everyday language and not through specialized codes or control languages. Japan launched in 1983 the "fifth generation program", with the objective of producing machines with real innovations. And in the USA it is developed
    Wave the personal computers, PC and supercomputers.
