Detailed explanation-1: -The first human computers appeared in the mid-1700s when people wanted to solve big, complex problems by approximation and repetitive solutions, such as determine when Halley’s Comet would return. Scientists realized that they could break complicated calculations apart so that a team could work on them.
Detailed explanation-2: -ENIAC, designed by John Mauchly and J. Presper Eckert, occupied 167 m2, weighed 30 tons, consumed 150 kilowatts of electricity and contained some 20, 000 vacuum tubes. ENIAC was soon surpassed by other computers that stored their programs in electronic memories.
Detailed explanation-3: -The term “computer", in use from the early 17th century (the first known written reference dates from 1613), meant “one who computes": a person performing mathematical calculations, before electronic computers became commercially available.
