What was the ENIAC made to do?
Completed by February 1946, ENIAC had cost the government $400,000, and the war it was designed to help win was over. Its first task was doing calculations for the construction of a hydrogen bomb.
Why was ENIAC invented?
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.
What is ENIAC when it was built?
February 15, 1946
ENIAC/Dates introduced
What was created in 1946 by engineers at the University of Pennsylvania that weighed 30 tons and filled a large room?
ENIAC
ENIAC was enormous. It contained 17,500 vacuum tubes, linked by 500,000 soldered connections. It filled a 50-foot long basement room and weighed 30 tons.
How many continuous hours maximum was ENIAC able to run without a failure in 1954?
116 hours
According to an interview in 1989 with Eckert, “We had a tube fail about every two days and we could locate the problem within 15 minutes.” In 1954, the longest continuous period of operation without a failure was 116 hours—close to five days.
What does the ENIAC stand for?
Electronic Numerical Integrator and Computer
ENIAC filled an entire room. ENIAC stands for Electronic Numerical Integrator and Computer. John Mauchly and J. Presper Eckert built the machine at the University of Pennsylvania at the behest of the U.S. military.

What was the purpose of the ENIAC computer?
Short for Electronic Numerical Integrator and Computer, the ENIAC was the first electronic computer used for general purposes, such as solving numerical problems.
When did John Eckert invent the ENIAC?
It was invented by John Presper Eckert and John Mauchly at the University of Pennsylvania to calculate artillery firing tables for the United States Army’s Ballistic Research Laboratory. Its construction began in 1943 and was not completed until 1946.
When was the ENIAC at the University of Pennsylvania dedicated?
ENIAC was formally dedicated at the University of Pennsylvania on February 15, 1946 and was heralded as a “Giant Brain” by the press.
How many subtractions can an ENIAC accumulator do?
ENIAC had 20 ten-digit signed accumulators, which used ten’s complement representation and could perform 5,000 simple addition or subtraction operations between any of them and a source (e.g., another accumulator or a constant transmitter) per second.
