Ones and zeroes doe not exist in real life; it is all analogue signals, interpreted as numbers.
You would like thee signals to be the only one on the cable, and you want them unaltered, so interpretation is flawless.
If the cable picks up or rejcts other signals, noise, it could upset f.i. feedback loops in amp stages, giving distortion.
It the signals that represent the numers themselves are distorted, interpretation and timind can suffer; this is jitter.
So a cable could do a few things wrong, and then there is impedance match which I frankly do not quite understand.
