ENIAC

ENIAC (; Electronic Numerical Integrator and Computer) was the first programmable, electronic, general-purpose digital computer, completed in 1945. Other computers had some of these features, but ENIAC was the first to have them all. ENIAC was Turing-complete and able to solve "a large class of numerical problems" through reprogramming. ENIAC was designed by John Mauchly and J. Presper Eckert to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory (which later became a part of the Army Research Laboratory). However, its first program was a study of the feasibility of the thermonuclear weapon. ENIAC was completed in 1945 and first put to work for practical purposes on December 10, 1945. ENIAC was formally dedicated at the University of Pennsylvania on February 15, 1946, having cost $487,000 (equivalent to $7,000,000 in 2024), and called a "Giant Brain" by the press. It had a speed on the order of one thousand times faster than that of electro-mechanical machines. ENIAC was formally accepted by the U.S. Army Ordnance Corps in July 1946. It was transferred to Aberdeen Proving Ground in Aberdeen, Maryland, in 1947, where it was in continuous operation until 1955.

Other computers had some of these features, but ENIAC was the first to have them all. ENIAC was Turing-complete and able to solve "a large class of numerical problems" through reprogramming. [...] ENIAC was, like the IBM Harvard Mark I and the German Z3 "Z3 (computer)"), able to run an arbitrary sequence of mathematical operations, but did not read them from a tape. Like the British Colossus, it was programmed by plugboard and switches. ENIAC combined full, Turing-complete programmability with electronic speed. The Atanasoff–Berry Computer (ABC), ENIAC, and Colossus all used thermionic valves (vacuum tubes). ENIAC's registers performed decimal arithmetic, rather than binary arithmetic like the Z3, the ABC and Colossus.

• ENIAC: The World’s First Computer | IEEE Life Members

  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 Laboratory. Although it was completed at the end of World War II, the ENIAC was created to help with the war effort against German forces. Its construction began in 1943 and was not completed until 1946. There was a shortage of male engineers during the war, so a team of six women computers did the programming: Betty Jean Jennings (Bartik), Marilyn Wescoff, Ruth Lichterman, Elizabeth Snyder, Frances Bilas, and Kathleen McNulty.

  Top Questions What was ENIAC? The ENIAC (Electronic Numerical Integrator and Computer) was the first programmable, general-purpose, electronic, digital computer, developed during World War II by the United States. Physicist John Mauchly, engineer J. Presper Eckert, Jr., and their team at the University of Pennsylvania's Moore School of Electrical Engineering, with guidance from Herman Goldstine and John von Neumann, began work on the ENIAC in early 1943. Completed in February 1946, it cost \$400,000. [...] When and why was ENIAC built? The Electronic Numerical Integrator and Computer (ENIAC) was the first programmable, general-purpose, electronic digital computer, built by the United States during World War II. Work began on ENIAC in early 1943, led by John Mauchly, J. Presper Eckert, and their colleagues at the Moore School of Electrical Engineering at the University of Pennsylvania. It was designed to calculate artillery range tables. Completed in February 1946, the ENIAC cost the government $400,000. Its first task was to perform calculations for the construction of the hydrogen bomb. 2 Britannica Sources 1. ENIAC 2. computer: ENIAC This answer is created from Britannica articles using AI.

ENIAC (Electronic Numerical Integrator And Computer) was the world's first general-purpose electronic computer. ENIAC is also considered the world's first programmable computer, although programming the computer was a complex, manual process that could take days. Even so, ENIAC was 1,000 times faster than anything else in existence at the time, capable of performing 5,000 additions per second. [...] As a product of World War II, ENIAC was designed and built for the United States Army to calculate artillery firing tables. However, it was ENIAC's power and general-purpose programmability that excited the public's imagination. When it was introduced to the world in 1946, ENIAC was referred to in the media as a "giant brain." [...] Physicist John Mauchly and electrical engineer J. Presper Eckert designed ENIAC and participated in its creation. Along with a team of engineers, mathematicians, programmers and other experts, they built and refined the computer in the basement of the Moore School of Electrical Engineering, which is now part of the School of Engineering and Applied Science at the University of Pennsylvania. The team started to work on the computer in 1943 and formally unveiled it in 1946. photo of ENIAC Introduced in 1946, ENIAC was the worlds' first general-purpose electronic computer.

  Penn Engineering Penn Engineering ## Celebrating Penn Engineering History: ENIAC Originally announced on February 14, 1946, the Electronic Numerical Integrator and Computer (ENIAC), was the first general-purpose electronic computer. Hailed by The New York Times as “an amazing machine which applies electronic speeds for the first time to mathematical tasks hitherto too difficult and cumbersome for solution,” the ENIAC was a revolutionary piece of machinery in its day. It was constructed and operated here at The Moore School of Electrical Engineering, now part of the School of Engineering and Applied Science. [...] The ENIAC now sits in the ground floor of the Moore Building, appropriately part of a computer lab. Now students sit within the shadow of its vacuum tubes and use descendants of ENIAC to accomplish their own tasks. In the lab, the parts of the ENIAC on display include the Cycling Unit, the Master Programmer Unit, a Function Table, an Accumulator and Digit Trays. Other parts of the original ENIAC were a Punch Card Reader, a Card Puncher, a Card Printer, a Division Unit, and a Square-root Unit. [...] After construction, the ENIAC was shipped to the military’s Aberdeen Proving Ground in Aberdeen, Maryland. There, it produced firing tables used for the military to correctly fire weapons at specific trajectories to accurately hit targets. In addition to ballistics, the ENIAC’s field of application included weather prediction, atomic-energy calculations, cosmic-ray studies, thermal ignition, random-number studies, wind-tunnel design, and other scientific uses. It is recalled that no electronic computers were being applied to commercial problems until about 1951.
