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.
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]
The four-sides model (also known as communication square or four-ears model) is a communication model postulated in 1981 by German psychologist Friedemann Schulz von Thun. According to this model every message has four facets though not the same emphasis might be put on each.
An example is the relation between sender and receiver: it influences the goal of communication and the roles played by the participants. Schramm's criticism of linear models of communication, which lack a feedback loop, has been very influential.
This decomposition is useful for the design and analysis of quantization behavior, and it illustrates how the quantized data can be communicated over a communication channel – a source encoder can perform the forward quantization stage and send the index information through a communication channel, and a decoder can perform the reconstruction ...
Paths of communication can be physical (e.g. the road as transportation route) or non-physical (e.g. networks like a computer network). Contents of communication can be for example photography, data, graphics, language, or texts. Means of communication in the narrower sense refer to technical devices that transmit information. [5]
The six factors of an effective verbal communication. Each corresponds to a communication function (not displayed in this picture). [1] Roman Jakobson defined six functions of language (or communication functions), according to which an effective act of verbal communication can be described. [2] Each of the functions has an associated factor.
[12] [10] Shannon and Weaver hold that models of communication should provide good responses to all three problems, ideally by showing how to make communication more accurate and efficient. [10] The prime focus of their model is the technical level, which concerns the issue of how to accurately reproduce a message from one location to another ...
