digital signal
Discrete electronic communication
A digital signal represents information as a sequence of discrete values, typically binary ones and zeros, rather than as a continuous wave.
Digital signals are more resistant to noise and degradation than analog signals, making them standard for modern communications: The cable carries a digital signal to the TV.
Computers process digital signals natively.
