Detailed explanation-1: -By the late 1940s, ENIAC, the first electronic digital computer was able to compute a ballistics trajectory in about 30 seconds, and it was much less time than the 20 hours required to perform the same calculations with a desk calculator.
Detailed explanation-2: -The basic machine cycle was 200 microseconds (20 cycles of the 100 kHz clock in the cycling unit), or 5, 000 cycles per second for operations on the 10-digit numbers. In one of these cycles, ENIAC could write a number to a register, read a number from a register, or add/subtract two numbers.
Detailed explanation-3: -ENIAC (Electronic Numerical Integrator And Computer) was the world’s first general-purpose computer. ENIAC was designed and built for the United States Army to calculate artillery firing tables.
