What is name of the first mainframe computer?

Answer 1

1943, it was called Colossus and was used by the British to crack the German high command's cyphers. By the end of the war 11 of them had been built, making it the only digital computer built in a quantity greater than 1 until after 1950.

Answer 2

IBM
Wrong!

IBM did not want to build computers until 1951 a year after the UNIVAC I was already being sold.

The original invention occurred before 1945 on the then classifiedProject PX, to build ENIAC. But it was never recorded who came up with the idea.

Answer 3

As the definition of supercomputer is a computer at least 10 times the speed and 10 times the storage of other computers of the same time period, other computers must precede supercomputers.

All early programmable computers were mainframes, as the vacuum tubes required lots of space.

Thus mainframe computers preceded supercomputers.

ENIAC much older then dos, apple or atari, it features key cards, and one module is as big an apartment. one key card can represent about only 60bits of data.
