Detailed explanation-1: -Started in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. Because of its electronic, as opposed to electromechanical, technology, it is over 1, 000 times faster than any previous computer.
Detailed explanation-2: -As one of the most important developments bringing about the personal computer revolution, transistors replaced vacuum tubes. Much smaller and consuming much less power, transistors helped make computers faster as well as more reliable and more efficient.
Detailed explanation-3: -It and subsequent computers employing vacuum tubes are known as first-generation computers. (With 1, 500 mechanical relays, ENIAC was still transitional to later, fully electronic computers.) Completed by February 1946, ENIAC had cost the government $400, 000, and the war it was designed to help win was over.
Detailed explanation-4: -The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania.
