ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [3] [4] Other computers had some of these features, but ENIAC was the first to have them all.

2025年1月25日 · ENIAC, the first programmable general-purpose electronic digital computer, built during World War II by the United States and completed in 1946. The project was led by John Mauchly, J. Presper Eckert, Jr., and their colleagues.

When the Army’s Ordnance Ballistic Research Laboratory approved the project, Eckert became the driving force behind what experts now consider to be the world’s first digital, general-purpose...

Originally announced on February 14, 1946, the Electronic Numerical Integrator and Computer (ENIAC), was the first general-purpose electronic computer.

2020年1月13日 · In 1946, Mauchly and Eckert developed the Electrical Numerical Integrator And Calculator (ENIAC). The American military sponsored this research because it needed a computer for calculating artillery-firing tables, the settings used for different weapons under varied conditions for target accuracy.

Developed in Philadelphia during World War II, the Electronic Numerical Integrator and Computer (ENIAC) made history as the world’s first general-purpose, nonmechanical computer.

2024年12月20日 · Colossus, ENAIC, 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.

2025年2月14日 · Among the first of such military-funded computing projects, ENIAC —designed by engineers John Mauchly and J. Presper Eckert—was commissioned by the US Army during World War II to calculate...

2021年5月2日 · Short for Electronic Numerical Integrator and Computer, the ENIAC was the first electronic computer used for general purposes, such as solving numerical problems. It was designed and invented by John Presper Eckert and John Mauchly at the University of Pennsylvania to calculate artillery firing tables for the US Army's Ballistic Research ...

2017年11月23日 · The ENIAC (Electronic Numerical Integrator and Computer), built in the years 1943 to 1946, is widely regarded as the first general-purpose electronic digital computer. The military needed ENIAC for the calculation of ballistic tables.
