I've just been reading the old computers thread. I've always been amazed at how the very first computer could have been made. At uni, we're been told that information get's stored in CPU registers and stuf, but I still don't see how it all works. I mean how can a bunch of 1's and 0's produce what we see today?
How was the very first computer made?
The way I understand it is that the inside of a computer is basically a whole load of switches that can be on or off. If it's on, there's a higher voltage than when it's off. That's fine - that's how a lightbulb works.
How can it actually DO stuff though? I mean, I can understand how it can tell if the "switch" is on or off, but how does it know what to do with information?
