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.
An asynchronous communication service or application does not require a constant bit rate. [2] Examples are file transfer, email and the World Wide Web. An example of the opposite, a synchronous communication service, is realtime streaming media, for example IP telephony, IPTV and video conferencing.
The communication skills required for successful communication are different for source and receiver. For the source, this includes the ability to express oneself or to encode the message in an accessible way. [8] Communication starts with a specific purpose and encoding skills are necessary to express this purpose in the form of a message.

Media richness theory states that all communication media vary in their ability to enable users to communicate and to change understanding.

This is the result of a shift from isolated text being relied on as the primary source of communication, to the image being utilized more frequently in the digital age. [2] Multimodality describes communication practices in terms of the textual, aural, linguistic, spatial, and visual resources used to compose messages. [3]
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 ]
