The correct answer is ENIAC.ENIAC was the first programmable general-purpose electronic digital computer, built during World War II by the US.ENIAC (Electronic Numerical Integrator and Computer)It was Turing-complete and able to solve "a large class of numerical problems" through reprogramming. The ENIAC was first made public on Friday, Feb. 15, 1946The ENIAC vision is largely credited to physicist John Mauchly and young engineer J. Presper Eckert, through U.S. Army experimental funding.Mauchly and Eckert went on to create UNIVAC, the first programmable computer designed for business applications.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. ENIAC could hold 20 10-digit numbers, and you could park a school bus inside itA group of female œcomputers was instrumental in building the ENIAC and a documentary focused on their role in the broader group of female œcomputers was instrumental in building the ENIAC and a documentary focused on their role in the broader World War II fight. er World War II fight.aAdditional InformationThe IBM 702 was IBM's response to the UNIVAC the first mainframe computer using magnetic tapes.Because these machines had less computational power than the IBM 701 and ERA 1103, which were favored for scientific computing, the 702 was aimed at business computing.The first production model was not installed until July 1955.?Whirlwind I was a Cold War-era vacuum tube computer developed by the MIT Servomechanisms Laboratory for the U.S. Navy. Operational in 1951.
