  • ABACUS
    300 BCE

    ABACUS

    Invented By: Babylonians
    Definition: The first and early aid for mathematical computations. Consisting of a frame mounted with rods along which beads or balls are moved.
  • NAPIER BONES
    1550

    NAPIER BONES

    Invented By: John Napier
    Definition: A manually-operated calculating device created by John Napier of Merchiston, Scotland for calculation of products and quotients of numbers.
  • JACQUARD'S LOOM
    1572

    JACQUARD'S LOOM

    Invented By:Joseph Marie Jacquard
    Definition: Uses punched cards to create fabric. It played an important role in the development of computers.
  • PASCALINE

    PASCALINE

    Invented By: Blaise Pascal
    Definition: It performed addition and subtraction by manipulating its dials. The first calculator or adding machine to be produced in any quantity and actually used.
  • DIFFERENCE ENGINE

    DIFFERENCE ENGINE

    Invented By: Charles Babbage (father of modern computers)
    Definition: This machine would be able to compute tables of number's such as algorithm tables.
    Fact: Ada Lovelace continued Charles Babbage proposal to finish the analytical engine. She is known as the first lady programmer.
  • ENIAC (ELECTRONIC NUMERICAL INTEGRATOR AND COMPUTER)

    ENIAC (ELECTRONIC NUMERICAL INTEGRATOR AND COMPUTER)

    Invented By: John Mauchly and J. Presper Eckert
    Definition: It calculate artillery tiring tables to be used by the United States Army's Ballistic Research Laboratory to help US troops during World War II. It was also used in nuclear research. It is an example of First Generation: Vacuum Tubes
  • UNIVAC (UNIVERSAL AUTOMATIC COMPUTER)

    UNIVAC (UNIVERSAL AUTOMATIC COMPUTER)

    Invented By: John Mauchly and J. Presper Eckert
    Definition: It was used to predict the result of the 1952 presidential election in the US and used as a census tabulation machine.
  • FIRST GENERATION: VACUUM TUBES

    FIRST GENERATION: VACUUM TUBES

    Invented By: John Ambrose Fleming
    Definition: The first computers used vacuum tubes for circuitry and magnetic drums for memory.They were open enormous and taking up entire room. It relied on machine language. They were expensive to operate and uses a lot of electricity.
  • SECOND GENERATION: TRANSISTORS

    SECOND GENERATION: TRANSISTORS

    Invented By: John Bardeen, William B. Shockley, and Walter H. Brattain
    Definition: Transistors replaced vacuum tubes and ushered in the second generation of computers. High Level Programming languages were also being developed at this time such as the use of COBOL and FORTRAN.
  • THIRD GENERATION: INTEGRATED CIRCUITS

    THIRD GENERATION: INTEGRATED CIRCUITS

    Invented By: Jack Kilby and Robert Noyce
    Definition: Instead of punched and printouts, users interacted with 3rd generation computers through keyboards and monitors and interfaced with an operating system.
  • FOURTH GENERATION: MICROPROCESSORS

    FOURTH GENERATION: MICROPROCESSORS

    Invented By: Ted Hoff
    Definition: The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. Fourth Generation computer also saw the development of GUIs (Graphical User Interface), the mouse and the handheld device.
  • FIFTH GENERATION: ARTIFICIAL INTELLIGENCE

    FIFTH GENERATION: ARTIFICIAL INTELLIGENCE

    Invented By: James Maddox
    Definition: It develops devices that respond to natural language input and are capable of learning and self-organization.
