Communication Models

3. Shannon Weaver Model

In 1948, Shannon was an American mathematician, Electronic engineer and Weaver was an American scientist both of them join together to write an article in Bell System Technical Journal‖ called “A Mathematical Theory of Communication” and also called as Shannon Weaver model of communication .According to the Shannon-Weaver Model, communication includes the following concepts: sender, encoder, channel, decoder, receiver and feedback. Furthermore, there is also concept of noise included in the model.
Elements of Model
1.Sender(Information Source)
The originator of message or the information source selects desire message.

2. Encoder(Transmitter)
The transmitter which converts the message into signals.

3. Channel
Channel is the medium used to send message.

4 .Decoder (Receiver)
Decoder is the machine used to convert signals or binary data into message or the receiver who translates the message from signals.

5. Receiver (Destination)
Receiver is the person who gets the message or the place where the message must reach. The receiver provides feedback according to the message.

6. Noise
Noise is the physical disturbances like environment, people, etc. which does not let the message get to the receiver as what is sent.

Advantages

• Concept of noise helps in making the communication effective by removing the noise or problem causing noise.
• This model takes communication as a two way process. It makes the model applicable in general communication.
• Communication is taken as quantifiable in Shannon Weaver model.

Disadvantages

• Feedback is taken as less important in comparison to the messages sent by the sender.
• The model is taken by some critics as a “misleading misrepresentation of the nature of human communication” as human communication is not mathematical in nature.
• The Shannon-Weaver model, by its very nature, encounters some difficulty when applied to human communication. Its origin as a model to be applied to telecommunication, rather than to interpersonal human communication, limits its application due to the linear, unidirectional makeup.
