Computer Evolution

Hello, Class:

The evolution of computers has gone through many stages throughout history from sliding beads to a multi-piece equipment today. The abacus, was invented about 5,000 years ago in Mesopotamia. The reflectivity was experienced by merchants keeping records of trading transactions. It then evolved into a mechanical calculator in the 17th century by Pascal, so he could help his father with duties. The transparency was the calculator went out to eight numerical digits. It was the first invention, besides writing, that the results were computed mechanically. The user did not have to write down the answers anymore. An American inventor named Herman Hollerith, found a way to store data on cards, which was very useful in taking dat for the U.S. Census. One punch represented one number, and any combination of two punches represented one letter. The storage cards reduced computational errors and each had a memory capacitance of eighty variables. Punch cards were the most commonly used way of computing data in the manufacturing and business industries until the 1960s.

Computers have evolved rapidly over the past few years, and this morning, iTunes announced it has released its 10 millionth song. The transparency is now so abundant with this new media.



  1. Freddie,

    These are some interesting facts taken right from the book "Windows and Mirrors" on computers:

    1949: three or four "computers"
    1954: US is spending 10 million a year on new "computer" technology, and a computer was used to project the poll results for the Eisenhower election.
    1962: 10,959 computers exist world wide, and interactive computer sharing programs are being developed at MIT
    1979: Over 500,000 person computers in the US, and the development of Apple and USENET(pages 45-48)

    It's a little crazy to see the facts of the computer timeline in the modern age, going back over 50 years ago.

    Here are a couple of links for computer history:
    On this link, it's fun to note that the most recent computer advancement, according to this site, was the introduction of the "iPad" last month.

  2. what do you conclude from the facts? and how does this relate to Windows and Mirrors?
