What happens physically when the user interacts with the computer, when a button is pressed on the keyboard for example?

Question

The question is the basics of how a computer works, most people seem to think it is magic or something, I would like to understand.

Is it an electric charge that goes on a chip? how does that translate into a screen?

Answer 1

At the very start of a button press it bounces, or sometimes just doesn’t quite but mostly connects. So the first part is a tiny circuit that de-bounces the button press to make each press into a single press.
