The correct option is A Mark I
The first machine to successfully perform a long
series of arithmetic and logical operations was Mark I.
A programmable, electromechanical calculator
designed by professor Howard Aiken. Built by IBM and installed at Harvard in
1944, it strung 78 adding machines together to perform three calculations per
second. It was 51 feet long, weighed five tons and used paper tape for input
and typewriters for output. Made of 765,000 parts, it sounded like a thousand
knitting needles according to Rear Admiral Grace Hopper. The Mark I worked in
decimal arithmetic, not binary, but it could go for hours without intervention.
Conceived by Harvard physics professor Howard
Aiken, and designed and built by IBM, the Harvard Mark 1 is a room-sized,
relay-based calculator. The machine had a fifty-foot long camshaft running the
length of machine that synchronized the machine's thousands of component parts
and used 3,500 relays.
