Telecom Crash Course

Аннотация

This is a book about telecommunications, which is the science of communicating over distance (t¯ele-, from the Greek . It is, however, fundamentally dependent upon data communications, the science of moving traffic between computing devices so that the traffic can be manipulated in some way to make it useful. Data, in and of itself, is not particularly useful, consisting as it does of a stream of ones and zeroes that is only meaningful to the computing device that will receive and manipulate those ones and zeroes.
