What is the difference between analog and digital system?

Digital as well as Analog System, both are used to transmit signals from one place to another like audio/video.

Digital system uses binary format as 0 and 1 whereas analog system uses electronic pulses with varing magnitude to send data.

Analog system uses sine waves.
