what is ENIAC , EDVAC, AND EDSAC?
ENIAC, short for Electronic Numerical Integrator And Computer,was the first general-purpose electronic computer. It was the first Turing-complete, digital computer capable of being reprogrammed to solve a full range of computing problems,although earlier machines had been built with some of these properties and it could not store a program. ENIAC was designed and built to calculate artillery firing tables for the U.S. Army’s Ballistic Research Laboratory.
EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. Unlike its predecessor the ENIAC, it was binary rather than decimal, and was a stored program machine.
Electronic Delay Storage Automatic Calculator (EDSAC) was an early British computer. The machine, having been inspired by John von Neumann’s seminal First Draft of a Report on the EDVAC, was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England. EDSAC was the first prac
