Computer Science Technology is a 3-12 months program that prepares students to work as entry-level software builders in small, medium or large enterprises. Began in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert on the Moore School of Electrical Engineering of the University of Pennsylvania. Due to its digital, as opposed to electromechanical, know-how, it is over 1,000 instances faster than any earlier computer. ENIAC used panel-to-panel wiring and switches for programming, occupied more than 1,000 sq. ft, used about 18,000 vacuum tubes and weighed 30 tons. It was believed that ENIAC had achieved more calculation over the ten years it was in operation than all of humanity had till that point.
