Annotated information flow diagram. 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 ...
The following outline is provided as an overview of and topical guide to communication: Communication – purposeful activity of exchanging information and meaning across space and time using various technical or natural means, whichever is available or preferred. Communication requires a sender, a message, a medium and a recipient, although ...
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.
Communication diagrams show much of the same information as sequence diagrams, but because of how the information is presented, some of it is easier to find in one diagram than the other. Communication diagrams show which elements each one interacts with better, but sequence diagrams show the order in which the interactions take place more clearly.
Visual communication is the use of visual elements to convey ideas and information which include (but are not limited to) signs, typography, drawing, graphic design, illustration, industrial design, advertising, animation, and electronic resources. [1]
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 ]
Most theorists identify Schramm's model with his 1954 book The process and effects of mass communication and present it as a reaction to earlier models developed in the late 1940s. [2] [3] [15] However, marketing scholar Jim Blythe argues that Schramm's model is of earlier origin and was already present in Schramm's 1949 [a] book Mass ...
The process data diagram. A process-data diagram (PDD), also known as process-deliverable diagram is a diagram that describes processes and data that act as output of these processes. On the left side the meta-process model can be viewed and on the right side the meta-data model can be viewed. [1]
