*A mathematical theory of communication*is a paper by

**Claude Shannon**published in two part in July and October 1948. The paper posed the basis for the modern information theory and the basi 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
