What is the difference in amount of vacuum tubes to amplifying circuits used to make computers?
I’m doing a report on the History of computers, and I can’t find this answer straight forward. I know computers switched from Vacuum tubes to amplifying circuits, and some computers used like 18,000 vacuum tubes- In contrast with the amplifying circuits, does each computer just need one? or a couple? I mean was it all those thousand tubes to the one circuit that made it such an improvement? Or did it just need …less.. Like 100 circuits or something?
The basic mechanics of the circuits remain the same, but a vacuum tube is big, like a light bulb. So the question is this, do you have a building to put your 18,000 vacuum tubes in, or would you rather fit 100,000 on a chip you can fit in your hand?
