Shannon Weaver communication model

The Shannon Weaver model actually preceded the Berlo's Model of communication. This model has following important components:Information source – 

Sender is the person who makes the message, chooses the channel and sends the message.

Transmitter –

Encoder is the sender who uses machine, which converts message into signals or binary data. It might also directly refer to the machine.

Channel –

Channel is the medium used to send message.

Receiver –

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

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.

The sender encodes the message and sends it to the receiver through a technological channel like telephone and telegraph. The sender converts the message into codes understandable to the machine. The message is sent in codes through a medium.

The receiver has to decode the message before understanding it and interpreting it. The receptor machine can also act as a decoder in some cases. The channel can have noise and the receiver might not have the capacity to decode which might cause problems in communication process.

Here, for instance, brain might be the sender, mouth might be the encoder which encodes to a particular language, air might be the channel, another person’s ear might be the receptor and his brain might be the decoder and receiver.

Similarly, air is the channel here, the noise present in his environment that disturbs them is the noise whereas his response is the feedback. There were only 5 components when the model was made. Noise was added later.
