Detailed explanation-1: -On June 14, 1951, Remington Rand delivered its first computer, UNIVAC I, to the U.S. Census Bureau. It weighed 16, 000 pounds, used 5, 000 vacuum tubes, and could perform about 1, 000 calculations per second.
Detailed explanation-2: -Originally priced at US$159, 000, the UNIVAC I rose in price until they were between $1, 250, 000 and $1, 500, 000. A total of 46 systems were eventually built and delivered.
Detailed explanation-3: -The machine contained 19, 000 vacuum tubes, 1500 relays, and several hundred thousand resistors, capacitors, and conductors. There were 20 accumulators, each capable of storing a 10 digit number. The ENIAC could perform about 5000 additions or 50 multiplications in one second.
Detailed explanation-4: -The UNIVAC I was designed as a commercial data-processing computer, intended to replace the punched-card accounting machines of the day. It could read 7, 200 decimal digits per second (it did not use binary numbers), making it by far the fastest business machine yet built.
