Most networking media send data using in which data is represented by only two discrete states: 0s and 1s. a. digital signals b. contiguous signals c. ramp signals d. exponential signals

i think digital signals

Explanation:

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values.[1][2][3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.
