Detailed explanation-1: -A skilled person with a desk calculator could compute a 60-second trajectory in about 20 hours. The Bush differential analyzer at the Moore School could produce the same result in 15 minutes, but the ENIAC required only 30 seconds.
Detailed explanation-2: -ENIAC was the fastest computational device of its time, able to do 5, 000 additions per second, but because it had no internal storage, it had to be programmed manually for each new set of calculations.
Detailed explanation-3: -Presper Eckert as chief engineer, and Goldstine as liaison. This was in 1943. It took about a year to design ENIAC, and 18 months to build it. By the time it was completed, in November 1945, the war had been over for three months.
Detailed explanation-4: -ENIAC was designed by Ursinus College physics professor John Mauchly and J. Presper Eckert of the University of Pennsylvania, U.S.
Detailed explanation-5: -Completed by February 1946, ENIAC had cost the government $400, 000, and the war it was designed to help win was over. Its first task was doing calculations for the construction of a hydrogen bomb. A portion of the machine is on exhibit at the Smithsonian Institution in Washington, D.C.
