Why computers use Binary Video (321)

Things I learned:

-Analog Signal:A signal that is proportional to the value it represents

-Digital Signal: A signal that represents a  value as a series of discreet values or digits

-Base Numerals: Representing a  number using "n" digits

Things I didn't understand:
-The analog systems was confusing
-I did not understand how the sound waves worked when this topic was applied to the speaker of cell phones

Something I want to learn:
-I want to learn sound wave frequencies and how to separate them from each other.
