ENIAC Full Form is Electronic Numerical Integrator and Computer. This was the first general-purpose and electronic computer. It was digital and could be reprogrammed. It could solve huge range of numerical problems. Though originally ENIAC was made to calculate ‘artillery firing tables’ for the Ballistic Research Laboratory of the United States Army, the initial programs had a feasible study of hydrogen bomb.
ENIAC was first announced in 1946 and the press considered it as a ‘Giant Brain’. This was because; the speed of ENIAC was 1000 times faster than electro-mechanical machines. This caused great excitement in the fields of science and industry. Several improvements have been made to ENIAC since 1948.
