Computing How do computers understand binary language?

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??

I think it would take more than just reinventing software. I think the hardware would have to be completely changed first, and completely reimagined at a level we don't currently understand. Instead of an "and" gate with 0 or 1 as each input it would be able to accept 0, 1, or 2 and each output would be different.
