1946: The Eniac Computer is Unveiled
ENIAC (Electrical Numerical Integrator And Calculator) was originally developed during Word War II to perform complex trajectory calculations for artillary, but the war ended before the machine was operational. But it continued to be used after the war, performing calculations for the design of the hydrogen bomb, weather prediction, cosmic-ray analysis, thermal ignition, random numbers, and wind-tunnel design. The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1,800 square feet of floor space, weighed 30 tons, and consumed 160,000 Watts of electrical power, making the lights go dim in Philadelphia each time it was powered up. On October 2, 1955 the ENIAC was shut down for the last time, but by then inventors John Mauchly and John Presper Eckert had already had the UNIVAC computer on the market for several years.
the answer is 1946.
The first ENIAC demonstration system (2 panels) was turned on in June 1944, the first time the complete ENIAC system was turned on was early November 1945. ENIAC ran continuously for 2 months (December 1945 through January 1946) on a fusion bomb simulation for Los Alamos. ENIAC was revealed to the press and public in February 1946.
Depends on how much of ENIAC, the first demonstrator composed of just 2 panels was turned on and running in June 1944, a useable system with all 20 accumulators was turned on and running in September 1945, the complete system was first turned on as a system in early November 1945. Here is the timeline:
Only one ENIAC computer was built. It consisted of a number of units wired together, and needed to be rewired to be reprogrammed. However, after 1948 a number of improvements were made to the original ENIAC computer
Only one was built. It is now on display in multiple pieces in various museums across the US and in other parts of the world.
As an interesting bit of trivia, in the mid-1990s, a modern design CPU was constructed to emulate the functionality of the ENIAC and it was built to be only about 5 millimeters by 7 millimeters in size. Compare this to the ENIAC itself which required almost as much room as a 4-bedroom house.

As a bit of interesting trivia, a modern design CPU was created in the mid-1990s to perform the same functionality as the ENIAC and it measured a scant 5 millimeters by 7 millimeters in size. Compare this to the size of the ENIAC which took almost as much room as a 4-bedroom house!
ENIAC was built by the Moore School of Electrical Engineering; at the University of Pennsyvania in Philadelphia
Design and construction began in June 1943 and was finished in November 1945.
ENIAC was completed in November of 1945. It completely filled a 30 foot by 50 foot room. It had over 17,000 vacuum tubes and 70,000 resistors.
ENIAC was designed and built in WW2 for the following purposes:Calculate new firing tables for existing artillery pieces in use where existing tables were found inadequateCalculate firing tables for new artillery piecesIt had to be able to do this much faster than the existing human computers then used for these tasks. However ENIAC was not operational until after the end of the war.
The only exhibit at the Smithsonian that had to do with computers was the ENIAC, a simple google search will pull up the wiki entry along with the museum website.
There was one, the first computer was ENIAC, short for Electronic Numerical Integrator And Computer.
The ENIAC has 17,468 vacuum tubes. These tubes were the first technology that made computers function. Modern computers do not use this technology.
Only one ENIAC was ever built. Its mechanism of programming was too inefficient and error prone.
many far better computers
Eniac had a multitude of bugs and crashes, the modern computers have a multitude of bugs and crashes. For the next 10 years no commonalities anymore between ENIAC and the future computers.

English.
No, the following digital computers preceded ENIAC: Harvard Mark I, ABC, Zuse Z1 & Z2 & Z3, Colossus Mark 1 & Mark 2. Also many analog computers preceded these.However ENIAC was the first general purpose programmable electronic digital computer.

nobody. it was invented then built, not discovered.
