How does hardware generate binary codes?
For instance, keyboard generates scancode "1E" when I press "A". But how?
P.S.: I assume software only interprets and processes binary data (not generates it)

A bit oversimplified, but you can think of it as the A key being wired to a circuit that produces the combination of signals that the computer (actually the keyboard controller) interprets as 1E.

You have a basic theoretical electronics question, not a problem using your computer. P.S. In a digital computer, ALL data is binary.
