Did you know the first computer used about 18,000 vacuum tubes? It weighed almost 50 tons! That's 100,000 pounds. Not only that, but it was so big it took up 1,800 square feet. That is bigger than some three-bedroom homes!It was called the ENIAC. J. Presper Eckert and John Mauchly invented it at the University of Pennsylvania. Construction began in 1943 and was not finished until 1946.The name is an acronym for Electronic Numerical Integrator and Computer. It was Turing complete and electronically digital. While there were a number of old-fashioned computers from that time, the ENIAC used decimal arithmetic instead of binary like the Colossus, ABC, and Z3.
