First Electronic Computers Invention in the World

in , ,

Taking calculations of 5,000 addition-subtraction, and 340 multiplication was considered to be a big marvel in the past. For nearly 3 years of researching and manufacturing, the first electronic computer, ENIAC I was first introduced at the University of Pennsylvania's Moore School of Electrical Engineering in 1946. The research forENIAC I, Electrical Numerical Integrator and Calculator, was developed by John Mauchly along with John Presper Eckert and sponsored by the American military. The ENIAC I, also seen as a "Giant Brain", contained inside 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. Costing $480,000, the ENIAC I has its floor space of 1,800 square feet and the weight of 30 tons. Let's take a look at the most wonderful images of the first electronic computers in the world including the ENIAC I.
