In a very simple form- in the analog world sound energy is TRANSFORMED in2 another form of energy which is PROPORTIONAL to the original. Every twist and turn is translated. In the digital world, NEW energy is GENERATED, based on measuring and analyzing the original. PARTS of the original are measured, the more U measure the more accurate the “picture” is painted.

It might b easier to think of a digitized picture:
In the newspaper 4 ex. the picture is made out of dots relating to parts of the original picture. The more dots used, the better the picture quality. Since the original measurements r kept as numbers, 1 may print exact copies of copies, generating the same picture over and over again.
When an analog picture is taken (like in a regular camera) ALL data is recorded. However, manipulating the picture like copying it, degrades picture quality every time another generation is produced.
