I’m very interested in learning how computers work, but can’t seem to find the exact information I’m looking for. My understanding is, and **please** correct me if I’m wrong, is that if you press the letter “A” on a keyboard, a circuit underneath will close which sends electricity to wires, and based on the combination of voltages on the wires, the computer outputs an “A”. But how does the computer know what do to with voltages? What do the voltages represent? At what point does any of this information get converted into binary, and once it does, what happens?
I don’t expect someone to be able to explain this like I’m five. For me, it’s a difficult, but really interesting subject. Any clarification and dumbing down is appreciated! I’m really hoping to get a better grasp on my understanding of all this.
Edit: I should’ve made the title “How do computers work?” Still wondering how computers know what to do with 1’s and 0’s, though.

The steps in between pressing a key like “a” and it printing on your screen are so many and rely on so many things that it’s practically impossible to explain it simply without massive oversimplification. Look into binary as a language and understand that at it’s most basic, all computers are interpreting large amounts of ones and zeros. Everything is ones and zeros. Even hardware works on this basic principle.
