Question 1

Describe the difference between a digital signal and an analog signal.

Accepted Answer

A digital signal consists of binary 1s and 0s,which may be sent electronically by varying voltages in copper media.A digital signal can also be represented as pulses of light on fiber optic media.An analog signal,however,is a signal that varies smoothly over time and doesn't use specific voltages to distinguish bits.
