Abstract:

Information theory began as a mathematical study of the process of communication. Originally associated with telecommunications, information theory proposes that information is the number of messages required to completely reduce the uncertainty of the situation. To apply this postulate to telecommunications, Shannon and Weaver developed a model which describes the communication system as a source formulating a message consisting of signals to be transmitted over a channel (where they are distorted by noise) to a receiver.
