Hi! Quick question

Why is the quality of digital transmission of data better than analogue transmission?

-Digital signals do not get corrupted by noise etc. You are sending a series of numbers that represent the signal of interest (i.e. audio, video etc.)
-Digital signals typically use less bandwidth. This is just another way to say you can cram more information (audio, video) into the same space.
