Information theory quantifies communication and storage of data from "summary" of Code by Charles Petzold
Information theory is the science of quantifying communication and storage of data. It deals with how much information can be transmitted through a communication channel, and how efficiently that information can be stored. The central idea of information theory is to measure information in terms of bits - the fundamental unit of information. The concept of bits was introduced by Claude Shannon, the father of information theory. A bit is a binary digit, representing a choice between two equally likely alternatives. In the context of communication, bits measure the amount of uncertainty reduced by receiving a message. For example, if you receive a message that could be one of four equally likely possibilities, it contains two bi...
