Digital Means Perfect Copies
The 0s and 1s of digital data mean more than than just on and off. They mean perfect copying. When information, music, voice and video are turned into binary digital form, they can be electronically manipulated, preserved and regenerated perfectly at high speed. The millionth copy of a computer file is exactly the same as the original. While this continually drives the software and content publishers crazy protecting their copyrights, it is nevertheless a major advantage of digital processing.
