History of Computers

  • The Difference engine

    The Difference engine
    This was Charles Babbage's invention that he created in Cambridge to calculate a series of values automatically. So it was possible to avoid the need for multiplication and division. It composed of around 25,000 parts, weigh fifteen tons (13,600 kg), and would have been 8 ft (2.4 m) tall. Even though Babbage received ample funding for the project, it was never completed.
  • Flying machine design

    Flying machine design
    Ada Lovelace produced the desgins for the first flying machine. It was mathematics that gave life to her wings
  • Analytical engine

    Analytical engine
    The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician Charles Babbage. It was first described in 1837, a design for a mechanical calculator. The Analytical Engine had an arithmetical unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer.
  • Cathode ray tube (CRT)

    Cathode ray tube (CRT)
    The experimentation of cathode rays is largely accredited to J.J. Thomson, an English physicist who, in his three famous experiments, was able to deflect cathode rays, a fundamental function of the modern CRT. The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the Braun tube. The cathode ray tube (CRT) is a vacuum tube containing an electron gun (a source of electrons) and a fluorescent screen used to view images.
  • Enigma machine

    Enigma machine
    Invented by German engineer Arthur Scherbius at the end of World War I, 1918. An enigma machine is any of a family of related electro-mechanical rotor cipher machines used for the encryption and decryption of secret messages.
  • The first general-purpose computers built

    The first general-purpose computers built
    Charles Babbage's Analytical Engine and Difference engine's were the first general-purpose computers were actually built.

    Colossus was the world's first electronic, digital, computer, Colossus and its successors were used by British codebreakers to help read encrypted German messages during World War II. Colossus was designed by engineer Tommy Flowers with input from Sidney Broadhurst, William Chandler, The prototype, Colossus Mark 1, was shown to be working in December 1943 and was operational at Bletchley Park by February. An improved Colossus Mark 2 first worked on 1 June 1944, just in time for the Normandy Land

    John Mauchly and John Presper Eckert developed the ENIAC I (Electrical Numerical Integrator And Calculator). The American military sponsored their research; the army needed a computer for calculating artillery-firing tables, the settings used for different weapons under varied conditions for target accuracy.
  • Computer mouse

    Computer mouse
    A relatively unknown inventor Douglas Englebart, wanted to create a way for people to interact with a computer screen. , he came up with all sorts of ideas, including a giant metal track ball and a knee operated device
  • Internet

    Internet as we know it today first started being developed in the late 1960's. The initial idea is Leonard Kleinrock's after he published his first paper entitled "Information Flow in Large Communication Nets" on May 31, 1961. In 1962 J.C.R. Licklider becomes the first Director of IPTO and gave his vision of a galactic network. In addition to the ideas from Licklider and Kleinrock, Robert Taylor helped create the idea of the network, which later became ARPANET.
  • Thin film transistor

    Thin film transistor
    The TFT, Thin Film Transistor came around and produced even more crystal clear images with faster refresh rates than TFD. As phones increase to more and more colors, TFD couldn't handle it. So TFT is usually used with displays of 4,096 colors, 65,000 colors, and 260,000 colors. But with the increased colors, refresh rates, and clarity, the power consumption is much higher resulting in more frequent battery charging.
  • Floppy discs

    Floppy discs
    The Inventor of First Floppy Disk is IBM Company and the year. Yoshiro Nakamatsu was the person who invented it for IBM.The disk was 8" in diameter with a magnetic coating, enclosed in a cardboard case with the capacity of one megabyte. Conversely to hard disks, the heads actually touch the disk, like in a cassette or video player that actually wears the media down over time.
  • Pong

    Pong is one of the earliest arcade video games, and is a tennis sports game featuring simple two-dimensional graphics. Pong was one of the first video games to reach mainstream popularity.

Allan Alcorn created Pong as a training exercise assigned to him by Atari co-founder Nolan Bush
  • GPS

    The GPS project was developed in 1973 to overcome the limitations of previous navigation systems. The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. GPS was created and realized by the U.S. Department of Defense and was originally run with 24 satellites. It became fully operational in 1994.
