#TBT First Fully Functional Computer: ENIAC (Electronic Numerical Integrator And Calculator).
ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania in attempt to calculate artillery firing table for the United States Army’s Ballistic Laboratory. It was also used for general purposes, such as solving numerical problems.The construction for ENIAC began in 1943 and was not completed until 1946. The hardware to build ENIAC consisted of 17,468 vacuum tubes and 15,000 relays; weighing in at almost 50 tons and used about 1,800 square feet of space! If we were to use a computer that big in our homes today, we would need to build an addition to the house.
What does the future hold for computers?
