Technology & Computers

The first commercial computer was sold in 1951, the UNIVAC.  It was

new, large and left many a little
uncomfortable.  In projecting the 1952 Presidential Election between Illinois Governor Adlai Stevenson and General Dwight Eisenhower, CBS News was provided the projection not long after the polls closed despite repeated on camera requests for information from UNIVAC.  CBS News elected to delay announcing the results until later in the evening due to fears the computer would be wrong.  Analysts had projected Dewey would win a majority of the vote.

With only 3.4 million votes recorded UNIVAC went against the pollsters.  With over 59.4 million votes actually cast, UNIVAC projected 43 of the 48 states going for Eisenhower and over 82% of the Electoral votes going to Eisenhower.  This projection was one of the most accurately projected elections (error was less than 0.1%) and in the least amount of time despite a projected landslide for Governor Stevenson.

From computers that weighed tons (not pounds) using vacuum tubes and memory tubes (not integrated circuits and high performance flash memory), computers have made vast inroads across society.  Now our telephones and watches are multifunction computers creating the Third Tier of computing.

As technologies expand and demand for information and access continues to grow with the interest in examining the massive amounts of data being gathered daily on the planet.

    -  5 Exabytes of new data are generated every 2 days globally.
        5 Exabytes of new data was generated from the dawn of time to 2003 globally.
        5 Exabytes, written as a numeric, is: 5,000,000,000,000,000,000 bytes.
         -  A big laptop PC can internally support 1,000,000,000,000 bytes (or 1 Terabyte)
             You will need 5 million big laptops to store the currently new data created every two days.
