Analog is the study of continuous circuits.
Digital is the study of (usually) binary circuits.
--------
Ex: an OpAmp is called an analog computer sometimes, because you can do things like Add, Subtract, Multiply, Divide, exponent, differentiate, or integrate voltages. (ex: 0.543V + 1.1V == 1.643V output). This is troublesome in practice because a bit of noise (ex: +.05V error) propagates.
This is in contrast to a digital computer, which encodes data into 0 or 1. There are things like PAM4 which encodes data as 0, 1, 2, or 3 (2-bits per signal), or other such "discrete steps". But the overall concept of "snapping" data to specific voltage levels allows you to fix noise issues.
