The message is sent in codes through a medium.The receiver has to decode the message before understanding it and interpreting it.

The Shannon and Weaver Model of Communication is a mathematical theory of communication that argues that human communication can be broken down into 6 key concepts: sender, encoder, channel, noise, decoder, and receiver. Communication Theory In the late 1940s Claude Shannon, a research mathematician at Bell Telephone Laboratories, invented a mathematical theory of communication that gave the first systematic framework in which to optimally design telephone systems. 0000000847 00000 n 0000003632 00000 n History at your fingertips At that point of time, Claude Shannon was a mathematician while Warren Weaver was an electrical engineer. Professor of Computer Science, University of Maine, Orono, Maine.
Shannon is noted for having founded information theory with a landmark paper, "A Mathematical Theory of Communication", that he published in 1948. The sender converts the message into codes understandable to the machine. Many believe this mathematical theory of communication was mainly developed by Claude Shannon alone and Warren Weaver had a minimal role. trailer << /Size 289 /Info 258 0 R /Root 269 0 R /Prev 1486837 /ID[<4341b3eeaa6471f31c0cbbfc928ccef1><5bc9a50ae928850d50bc96f1f08b79b5>] >> startxref 0 %%EOF 269 0 obj << /Type /Catalog /Pages 261 0 R /Metadata 259 0 R >> endobj 287 0 obj << /S 1461 /Filter /FlateDecode /Length 288 0 R >> stream Pour le choix le plus simple, l’unité d’information est 2 (2 puissance 1 ). ( entropie forte ).Plus une situation est hautement organisée et prédictive ( « le soleil se couche en fin de journée »), le hasard ou le choix sont limités, plus l’information ( ou entropie ) est faible.« La quantité précisément nécessaire à l’établissement de l’information correspond exactement à la notion thermodynamique d’entropie. The Shannon and Weaver’s model of communication was created in 1954 when Claude Elwood Shannon and Warren Weaver joined together and wrote an article titled “A Mathematical Theory of Communication” in “Bell System Technical Journal”.
Shannon was an American mathematician whereas Weaver was a scientist. Naturellement on peut penser que le bruit abime le message transmis ( on n’a pas tout entendu ),et donc que l’information transmise diminue . 0000071206 00000 n As the underpinning of his theory, Shannon developed a very simple, abstract model of communication, as shown in the figure.
