Difference between digital communication and other communication

[1R1]

So what is the difference between "digital communication" and other communication, anyway? Does "digital" mean it uses HTML?

When information is transferred as distinct bits of information, which are essentially numbers, it's called digital. It's much easier to store, retrieve, and process information without losing or changing it when it is transferred digitally. Any information from a computer (including HTML) is by its nature digital, and in the not-too-distant future, telephone, television, radio, and even motion picture production will be digital.
