Well, if you consider what the first calculators looked like, compared to the first computer, they were TINY... The "first" computer was the ENIAC
http://en.wikipedia.org/wiki/ENIACHere are some of the highlights... Quote »ENIAC was massive compared to modern PC standards. It contained 17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and around 5 million hand-soldered joints. It weighed 30 short tons (27 t), was roughly 8.5 feet (2.6 m) by 3 feet (0.9 m) by 80 feet (26 m), took up 680 square feet (67.6 m²), and consumed 150 kW of power. The first computer "bug" was reported in 1947..!!

(See the picture above.) The entry reads: "First actual case of bug being found."(See the link at the bottom of this page for a much larger version of this picture.)The word went out that they had "debugged" the machine and the term "debugging a computer program" was born.Although Grace Hopper was always careful to admit that she was not there when it actually happened, it was one of her favorite stories.WoW
