WebbAccording to Shannon (1948; see also Shannon and Weaver 1949), a general communication system consists of five parts: − A source S, which generates the message to be received at the destination. − A transmitter T, which turns the message generated at the source into a signal to be transmitted.

The information entropy Η can be calculated for any probability distribution (if the "message" is taken to be that the event i which had probability pi occurred, out of the space of the events possible), while the thermodynamic entropy S refers to thermodynamic probabilities pi specifically. The difference is more theoretical than actual, however, because any probability distribution can be approximated … ipad enable location services
