    Alan Turing made the Turing Machine that was capable of computing anything that was computable

    The Turing Machine had a read/write/scanner head which a paper tape passing through it. The paper tapes sybolised either '0' or '1'.This machine is behind all of the modern computers today.

    Konrad Zuse, a German Engineer finished the Z3 Computer

    Zuse wanted to prove that it was possible to have a reliable computing device that calculated hard arithmetic calculations. The Z3 was said to be the first binary floating number and switching system based computer that actually worked.

  • Period: to

    ENIAC was created, the first electronic general purpose computer

  • Grace Hopper found a moth in a computer, later the term 'debugging' or 'bug' etc. for a computer was used because of her

    Grace Hopper found a moth in a computer, later the term 'debugging' or 'bug' etc. for a computer was used because of her

    Grace Hopper was a United States Mathmatician and Computer Scientist. She was also in the US Navy. She found a moth in between points in Relay 70. They put the moth in a log book. Underneath she wrote: 'First actual case of bug being found'. That was the first time someone used that word for a glitch

  • John Bardeen, Walter H. Brattain and William Shockley produced their first semiconductor device.

    John Bardeen, Walter H. Brattain and William Shockley produced their first semiconductor device.

    William Shockley created a physics group from Bell Lab to replace unreliable devices. The first time they tried, it didn't work. A year later, a theoretical physicist named John Bardeen suggested something that could help and with the help with Walter Brattain started researching. On December 16th, 1947, they made the first semi-conductor amplifier.
