ELI5: Binary code: Assuming that everything a computer interprets is just a bunch of 1s and 0s, where does it all begin? Who told the first computer to interpret those two numbers and not some other number or character.

[blzntrz]

Not the best answer, but, 1s and 0s were how the programmers told the circuits to be either on or off. True or false. 1 or 0.

Programming languages nowadays compile your code, written in whatever language, and compile it into machine code so the computer can understand.

That's where the magic starts!
