Humans are conversant in many media {music, dance, painting}, but all of them are analog except for the written word, which is naturally expressed in digital form {i.e. it is a series of discrete symbols-every letter in every book is a member of a certain character set, every "a" is the same as every other "a," and so on}. As any communications engineer can tell you, digital signals are much better to work with than analog ones because they are easily copied, transmitted, and error-checked. Unlike analog signals, they are not doomed to degradation over time and distance. That
