When was the first computer turned on?In: Computer History |
Answer
At 27 tonnes and the size of an entire room, the world's first computer is just as elaborate as its name suggests — ENIAC or Electronic Numerator Integrator Analyser and Computer. True to form, ENIAC also makes big noises, cracking and buzzing while performing an equation of 5,000 additions. Before the invention of ENIAC, it took a room full of people to calculate a similar equation. • ENIAC spanned nearly 17 metres and filled most of a 9-by-17 metre room. It could perform 38 divisions and 357 multiplications in less than a second. • ENIAC was noisy and emitted an incredible heat because it had 17,000 vacuum tubes — sealed glass containers conducting electrical currents. • Scientists at the University of Pennsylvania first invented ENIAC for the U.S. army in 1945.
so there you have it, 1945.
