The Electronic Numerical Integrator And Computer (ENIAC) was the first electronic general-purpose computer. It was Turing-complete, digital, and capable of being programmed to solve “a large class of numerical problems”. Initially designed to calculate artillery firing tables for the United States Army’s Ballistic Research Laboratory, when ENIAC was made public in 1946 it was heralded in the press as a “Giant Brain”. It had a speed of one thousand times that of electro-mechanical machines.
