CRITICISM OF SHANNON- WEAVER MODEL OF COMMUNICATION

• To discover how communication message could be converted into electronic signals most efficient and ;

• how those signals could be transmitted with minimum error.

Goals

Reason

To identify the quickest and most efficient way to get message from one point to another.

Claude Elwood Shannon

He was an American Mathematician, electronic engineer, and a cryptographer known as “father of information theory”. Shannon is famous for having founded information theory with landmark paper

that he published in 1948.

Born April 30, 1916Petoskey, Michigan, U.S.

SENDER

Source of Information

ENCODER

CHANNEL

Transmitter

DECODER

RECEIVER

Reception Destination

FEEDBACK

NOISE

Sender- the originator of message or the information source selects desire message.

Encoder- the transmitter which converts the message into signals

Signal- any communication that encodes the message.

Channel- choice of media (voice- phone, television, printed words) and any choice of form of media (story telling, direct description, interrogation, degree of engagement). Here noise can interfere with communication.

Noise Source- distraction

Decoder- the reception place of the signal which converts signals into message. A reverse process of encode.

Receiver- the destination of the message.

Criticism of Shannon-Weaver model of communication :

1.       One of the simplest model and its general applied in various communication theories2.       The model which attracts both academics of Human communication and Information theorist to leads their further research in communication3.       It’s more effective in person-to-person communication than group or mass audience4.       The model based on “Sender and Receiver”. Here sender plays the primary role and receiver plays the secondary role (receive the information or passive)5.       Communication is not a one way process.  If it’s behaved like that, it will lose its strength. For example: Audience or receiver who listening a radio, reading the books or watching television is a one way communication because absence of feedback6.       Understanding Noise will helps to solve the various problems in communication
