At a very low level, a hardware designer will decide what means 1 and what means 0. For example, they might say "Anything above 3.7V means 1, and anything below 1.9V means 0, and any voltage in between should be avoided and shouldn't happen. And then they design a NAND gate with three inputs and say "If all three inputs are above 3.7V then the ...
