The History of Computers

  • Z1 Computer

    Z1 Computer
    Konrad Zuse invented the Z1 computer which was the first freely programmable computer.
  • Z3 Computer

    Z3 Computer
    Konrad Zuse finishes the Z3 computer. The Z3 was an early computer built by German engineer Konrad Zuse working in complete isolation from developments elsewhere. Using 2,300 relays, the Z3 used floating point binary arithmetic and had a 22-bit word length. The original Z3 was destroyed in a bombing raid of Berlin in late 1943. However, Zuse later supervised a reconstruction of the Z3 in the 1960s which is currently on display at the Deutsches Museum in Munich.

    Advances in Software and Language
    Claude Shannon´s "The Mathematical Theory of Communication" showed engineers how to code data so they could check for accuracy after transmission between computers. Shannon identified the bit as the fundamental unit of data and, coincidentally, the basic unit of computation.

    John Presper Eckert and John W. Mauchly ivented the UNIVAC which was the first commercial computer and was able to pick presidential winners.
