The ENIAC: Electronic Numerical Integrator And Calculator Inventors : J. Presper Eckert and John Mauchly -University of Pennsylvania Date: Construction begins in 1943 and is completed in 1946 Statistics: 1,800 square feet 50 tons 18,000 vacuum tubes In one second, the ENIAC could perform 5,000 additions, 357 multiplications or 38 divisions. Because it used vacuum tubes instead of switches and relays, it was faster than any other computation device of its time. The ENIAC required a great deal of maintenance time and would take hours to reprogram ( Bellis ). Although completed after the war, the U.S. Army contracted with the Moore School of Engineering to create a device whose calculations could be used against German forces (Computer history - 1940 – 1960) ENIAC’s first major job, involved many thousand computations connected with top-secret studies on thermonuclear reactions. It was completed in 2 hours (Milestones: Electronic Numerical Integrator and Computer). View Picture

Williams Tube The Williams Tube is invented in 1946 by Freddie Williams and Tom Kilburn in December 1946. It was a cathode-ray tube (CRT) storing device and a data storage device used with early computers. The tube was capable of storing between 512 and 1024 bits of data (Computer history - 1940 – 1960) http://en.wikipedia.org/wiki/File:Williams-tube.jpg Back to Main Menu Back to 1940’s

The UNIVAC I - 1951 Manufactured by Remington Rand for the U.S. Census Bureau. The leaders of the project were J. Presper Eckert and John Mauchly Price: 1 million dollars Speed: 1,905 operations per second (Timeline of computer history) The UNIVAC contained thousands of vacuum tubes. It used punch cards and switches for inputting data and punch cards for outputting and storing data ( Computer history - 1940 – 1960) http://www.computerhistory.org/timeline/?category=cmptr Back to Main Menu Back to 1950’s
