how does a computer really work

All it really is is a piece of silicon with a bunch of wires running through it...how is it able to stuff with a bunch of electrical impulses...like how is it actually displaying this site to me? How does it actually perform mathematical calculation s with just metal and electric? It really puzzles me...

 

Binary code, simple iteration, that's all she wrote.

 

Its all a bunch of switches stuck together,say if you had a light that could only be turned on when 2 switches were pressed by 2 different people,you know when the light comes on that there are 2 people there so that light has just "computed" for you that there are 2 people there without you having to count them,if you exchange the people for numbers and use a hell of alot more switches,exchange the bulb for a monitor you have a computer!
