Who invented the computer?

  • In 1837, Charles Babbage designed a general purpose computer, the Analytical Engine, but never built it.
  • Between 1934 and 1937, Church, Turing et al. defined the general purpose computer, but didn’t design one.
  • In 1941, Konrad Zuse built the first general purpose computer, the Z3, but didn’t know it was general purpose and didn’t use it that way.
  • From 1943 to 1946, Mauchly and Eckert finally built a computer, ENIAC, that was designed to be general-purpose.

    Don’t forget Wilhelm Schickard who designed one of the first mechanical calculators in 1623. Our University’s CS department is named after him đŸ˜‰

    I do not think that Colossus can be seen as a Computer (turing complete), due the Nature of it’s purpose of “brute-force” code hacking.
    Enigma can be seen as a LFSR with 25 states, with a Dynamic changing modulo (distance) which permuated constant on same starting key wich each typing.
    Fatally Enigma had a Reflection disc, which made it attackable
    This is what Colossus Tried to do: It tried to find matching pairs on daily (constant key sequence) transmitted message , which was then used for calculating back the Disk position and this lead to the decryption of all daily messages

    if you assume: 3 Disks, starting at AAA
    then
    AAAA -> YBDR
    BBBB -> OAJY
    AB on same position –> that’s the reflection disk
    The chanche that this happens is on a 3 Disk system 1:25

    and if fatally, in a long sequence
    AAAAA AAAAA AAAAA AAAAA AAAAA AAAAA AAAAA AAAAA AAAAA
    YBDRB UHWIE ERJRO HPVZI CDIJI ZUNNP JLIOB SSJIK SUDNQ
    (in our case AB) happend again, then you had a VERY good hint for the hamming distance

    And the Manchester Science Museum has a working replica of the Baby, which is demonstrated every day(?) at a certain time.

    There’s also the ABC. Apparently programmability was planned but never implemented.

    And Heron’s robots, of course.
