Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
The choice of the right channel affects successful communication. For example, a classroom teacher has to decide which contents to present orally, by talking about them, and which ones to present visually through books. The choice also depends on the receiver whose decoding skills may be better for some channels than for others. [51] [60]
The five essential parts of the Shannon–Weaver model: A source uses a transmitter to translate a message into a signal, which is sent through a channel and translated back by a receiver until it reaches its destination. [1] The Shannon–Weaver model is one of the first models of communication.

Backchannel communication is present in all cultures and languages, though frequency and use may vary. For example, backchannel responses are not only a key component of oral languages but they are also important in sign languages. [8] Another example is Germans produce smaller backchannel responses and use back channel responses less ...
A model of communication is a simplified presentation that aims to give a basic explanation of the process by highlighting its most fundamental characteristics and components. [16] [8] [17] For example, James Watson and Anne Hill see Lasswell's model as a mere questioning device and not as a full model of communication. [10]
Channels of communication also affect the effectiveness of interpersonal communication. Communication channels may be either synchronous or asynchronous. Synchronous communication takes place in real time, for example face-to-face discussions and telephone conversations.
As Daft and Lengel suggest, face-to-face communication is the best medium for equivocal, or complex, communication between two people, whereas less-rich mediums can be effective so long as the complexity of the information being transferred from one party to the other does not exceed the channel's capacity.
