The following channels are the principal multi-terminal channels first introduced in the field of information theory [citation needed]: A point-to-multipoint channel , also known as broadcasting medium (not to be confused with broadcasting channel): In this channel, a single sender transmits multiple messages to different destination nodes.
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]
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]
Public relations can facilitate dialogue by establishing channels and procedures for dialogic communication. [2] Dialogic theory argues that organizations should be willing to interact with publics in honest and ethical ways in order to create effective organization-public communication channels. [3]
An information flow diagram (IFD) is a diagram that shows how information is communicated (or "flows") from a source to a receiver or target (e.g. A→C), through some medium. [1]: 36–39 The medium acts as a bridge, a means of transmitting the information. Examples of media include word of mouth, radio, email, etc.
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.
Channel expansion theory offers supports for effective communication between doctors and patients with chronic disease. Chronic disease usually happens to people in their older ages. This is a time period that many have lost their chances to engage with certain media channels.
Information and communication represent power in organizations. The ability to communicate well, both orally and in writing, is a critical managerial skill and a foundation of effective leadership. Through communication, people exchange and share information with one another and influence one another's attitudes, behaviors, and understandings.
