History of Computers

  • Charles Babbage

    Charles Babbage
    In 1834 Charles Babbage designed the first automatic calculator called the Anylitcal Engine.
  • Z1 computer

    Z1 computer
    The first computer to include certain features integral to todays systems. Such as a control unit and separate memory functions.
  • Eniac

    Eniac
    It used nearly 18,000 vacuum tubes and filled approximately 1,800 square feet of floor space. It remained in use until 1955.
  • 1st generation computers

    1st generation computers
    The first generation of computers is said by some to have started in 1946 with ENIAC, the first 'computer' to use electronic valves (ie. vacuum tubes). Others would say it started in May 1949 with the introduction of EDSAC, the first stored program computer. Whichever, the distinguishing feature of the first generation computers was the use of electronic valves.
  • Univac

    Univac
    First commercially successful electronic digital computer. Operated on magnetic tape. The Univac gained notoriety when, in a 1951 publicity stunt it was used to predict the outcome of the Stevenson-Eisenhower. It correctly identified Dwight .D. Eisenhower the victor. It was considered a first generation computer.
  • 2nd generation computers

    2nd generation computers
    The transition from first generation to second generation of computers was not abrupt. There was all round development in technology, designs and programming languages. Diode and transistor technology formed the basis of the electronic switches and the switching time came down to around 0.3 microseconds.
  • Jack Kilby

    Jack Kilby
    He took pride in the realization of the first integrated circuit in 1958.
    he was also awarded the Nobel pize in physics.
  • BASIC

    BASIC
    Powerful programming language used to build a wide range of windows applications. Quick interface. Its real easy for a programmer to learn how to use.
  • 3rd generation computers

    3rd generation computers
    Despite the fact that transistors were clearly an improvement over the vacuum tube, they still generated a great deal of heat, which damaged the computer's sensitive internal parts. The quartz rock eliminated this problem. Jack Kilby, an engineer with Texas Instruments, developed the integrated circuit (IC) in 1958. The IC combined three electronic components onto a small silicon disc, which was made from quartz. Scientists later managed to fit even more components on a single chip, called a
  • 4th generation computers

    4th generation computers
    After the invention of the integrated circuit, the next step in the computer design process was to reduce the overall size. Large scale integration (LSI) could fit hundreds of components onto one chip. By the 1980's, very large scale integration (VLSI) squeezed hundreds of thousands of components onto a chip. Ultra-large scale integration (ULSI) increased that number into the millions. The ability to fit so much onto an area about half the size of a U.S. dime helped diminish the size and pri
  • Introduction of the GUI

    Introduction of the GUI
    Allowed users to interact with the computers more easily.
  • Altair Computer

    Altair Computer
    It came with a do it yourself kit for $395 or $498 for a fully assembeled unit. It had no keyboard, no monitor and completely not user friendly.
  • Bill Gates

    Bill Gates
    Bill Gates and paul Allen used BASIC to write their program for Altair as we noted earlier this program led to the creation of Microsoft, a company that produced computer software.
  • Steve Jobs

    Steve Jobs
    CEO of Apple Inc., Co-Founder & Chairman.
  • Apple ll

    Apple ll
    It included a color monitor, sound and game paddles. Priced around 1,300. The operating system was stored in read- only memory. (ROM)
  • WordStar

    WordStar
    First word processing application.
  • Visicalc

    Visicalc
    First electronic spreadsheet app. 1978
  • Herman Hollerith

    Herman Hollerith
    Herman Hollerith while working for the U.S census Bureau, was the first to talk Jacuards punch-card concept and apply it to computing with his Hollerith Tabulating Machine.
  • Osborne Computer

    Osborne Computer
    It was a portable computer, the first to be exact. It was 24.5 punds. Featured a minuscule 5-inch screen and carried a price tag of 1,795 dollars. Compaq bought the Osborne design.
  • PageMaker

    PageMaker
    The first desktop publishing software.
  • Excel

    Excel
    One of the first spreadsheets to use a graphical user interface.
  • Mosaic

    Mosaic
    Allowed users to to view multimedia on the web. Causing internet traffic to increase by nearly 350%
  • Netscape

    Netscape
    In 1994 a team of developers launched the Netscape web browser, which soon became a predominant player in browser software.
