ENIAC was developed by Dr. John Mauchly and J. Presper Eckert during World War II at the Moore School of the University of Pennsylvania. In 1940 Dr. John Vincent Atanasoff attended a lecture by Mauchly and subsequently agreed to show him his binary calculator, the Atanasoff-Berry Computer (ABC), which was partially built between 1937-1942. Mauchly used ideas from the ABC in the design of ENIAC, which was started in June 1943 and released publicly in 1946. ENIAC was not the first digital computer, Konrad Zuse's Z3 was released in 1941. Though, like the ABC, the Z3 was {electromechanical} rather than electronic, it was freely programmable via paper tape whereas ENIAC was only programmable by manual rewiring or switches. Z3 used binary representation like modern computers whereas ENIAC used decimal like mechanica スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016. All Rights Reserved.
