"A Mathematical Theory of Communication" is an influential^[1][2] 1948 article^[3] by mathematician Claude E. Shannon. It was renamed "The Mathematical Theory of Communication" in the book^[4], a small but significant title change after realizing the generality of this work.

Description

Shannon's diagram of a general communications system, which shows the process of information that produces a message. The article was one of the founding works of the field of information theory. Shannon expanded the ideas of this article in a 1949 book with Warren Weaver titled The Mathematical Theory of Communication (ISBN 0-252-72546-8). The book was released as a paperback in 1963 (ISBN 0-252-72548-4). The article was divided up into 3 levels of communication problems. These problems were: 1) technical, 2) semantic, and 3) influential. First briefly explains the symbols of communication transmitted, then the transmitted symbols conveying meaning, and lastly the received meaning affect. Shannon's article laid out the basic elements of communication:

• An information source that produces a message
• A transmitter that operates on the message to create a signal which can be sent through a channel
• A channel, which is the medium over which the signal, carrying the information that composes the message, is sent
• A receiver, which transforms the signal back into the message intended for delivery
• A destination, which can be a person or a machine, for whom or which the message is intended

It also developed the concepts of information entropy and redundancy, and introduced the term bit as a unit of information.
