ENIAC (which meant "Electronic Numerical Integrator And Computer")[1] was a computer built between 1943 and 1946. It was designed by two people called John Mauchly and J. Presper Eckert. The machine was built out of nearly 17,500 vacuum tubes,[2] 7,200 diodes and many miles of wire.[3] It took up 1,800 square feet (170 m2) of space, which is the size of a large room.[4]
