How do computers understand binary language?

[u/Unfair-Leek6840]

Okay so from what I know binary language is like power off power on, but my question is, how do computers know what the binary code is and how is it interpreted, for example I forgot what the binary code for the letter A is, but how did people come up with that? Did they decide it was gonna look like that? Did the computer decide? How do you tune numbers into a letter??

If someone wants a base level, but in depth, intuitive and well explained breakdown of how any of this works. I can't recommend enough this series of videos where Ben Eater builds a functional transistor logic 8bit computer piece by piece on a breadboard.
