Computer History

By andreibalaj123

  • The First Computer

    The first freely programmable computer came into play.

  • Mark 1

    First electromechanical computer, using mechanical devices, weighd 5 tons, it used abut 750,000 parts

  • Electronic vacuum tubes

    Controlling electric current through a vacuum in a sealed container

  • ENIAC

    First, electronic High-Speed, General-Purpose Computer Using vacuum tubes

  • The transistor

    The transistor was invented by Bell Telephone Company. It wasn't a computer in itself'but it was a vital computer component.

  • EDSAC & EDVAC

    First stored-program computers

  • LEO & UNIVAC

    First commercial automatic computers
  • Period: to

    LEO & UNIVAC

    Were used vacuumtubes as main logic element, punch cards and rotating magnetic drums to store data compilers to trasnform codes

  • IBM

    International Business Machines came out with their first computer machine.

  • Bank computers

    The first bank computers were invented. They used MICR'or magnetic ink character recognition'to read checks.

  • The computer chip

    Jack Kilby and Robert Noyce invented the integrated circuit'better known as the computer chip.

  • Video games

    Spacewar games invented the first computer video games.

  • The mouse is invented

    Douglas Engelbart invented the computer mouse. He called it the mouse because the cord came out the back like a tail.
  • Period: to

    LEO & UNIVAC

    were used integrated circuits as logic element, and magnetic core internal memories began to give way to metal oxide semiconductor memory. They used silicon-backed chips

  • The internet

    The first internet was called ARPANET. The original internet wasn't used very widely because not many people had access to it.
  • Period: to

    The first personal computers

    IBM and Apple were just a couple of the brands that put out the first personal computers.

  • Microsoft is born

    Bill Gates worked with Paul Allen to develop BASIC for the Altair 8800.

  • Apple

    First highly successful mass produced personal microcomputer, designed by Steve Wozniak
  • Period: to

    Apple

    Integrated circuits became large-scale and very large-scale, meomry logic, and control circuits were in microporcessors they aooeared home-use PC's language software are everyday

  • IBM PC

    MS-DOS was developped

  • First Apple Mac

    targeted mainly at the home, education, and creative professional markets, by Apple Inc.

  • Microsoft expands

    Microsoft made a program that was compatible with IBM computers. This let more people come into contact with the now well-known program.

  • The internet as we know it

    im Berners Less came up with the World Wide Web. He started a computer revolution.

  • The laptop comes into play

    The first laptop computer'the Power Book 100'came out. There were other portable computers before this'but they were very clunky and expensive.

  • World Wide Convention

    the first internet convention was held.

  • Mini computers

    Nokia introduced a phone that had internet capabilities. This started a revolution of devices that were small'portable computers.

  • Now a day

    Now, they're being developed artifical inteligence, applications, parallel processing, superconductors, quantumcomputation, nanotechnology, etc. to improve computers and they are more and more technological
