The source–message–channel–receiver model is a linear transmission model of communication. It is also referred to as the sender–message–channel–receiver model, the SMCR model, and Berlo's model. It was first published by David Berlo in his 1960 book The Process of Communication.
The channel is the sensory route on which the signal travels. For example, expressing one's thoughts in a speech encodes them as sounds, which are transmitted using air as a channel. Decoding is the reverse process of encoding: it happens when the signal is translated back into a message. [16] [17] [18]
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 ]
It is a process of interpretation and translation of coded information into a comprehensible form. The audience is trying to reconstruct the idea by giving meanings to symbols and by interpreting messages as a whole. Effective communication is accomplished only when the message is received and understood in the intended way.
[10] [16] Once the message reaches the receiver, the reverse process of decoding is applied: the receiver attaches meaning to the signs according to their own field of experience. This way, they try to reconstruct the sender's original idea. The process continues when the receiver returns a new message as feedback to the original sender. [1] [20]
Shannon and Weaver focus on telephonic conversation as the paradigmatic case of how messages are produced and transmitted through a channel. But their model is intended as a general model that can be applied to any form of communication.

Mass communication is "the process by which a person, group of people or organization creates a message and transmits it through some type of medium to a large, anonymous, heterogeneous audience." [ 2 ] This implies that the audience of mass communication is mostly made up of different cultures and behavior and belief systems .
