Media richness theory states that all communication media vary in their ability to enable users to communicate and to change understanding. [5] The degree of this ability is known as a medium's "richness." MRT places all communication media on a continuous scale based on their ability to adequately communicate a complex message. [6]
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.
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.
Real-time communication systems are generally understood as one of two types: Hard Real-Time (HRT) and Soft Real-Time (SRT). [2] The difference between a hard and soft real-time communication system is the consequences of incorrect operation.
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.
This rise in computer-controlled communication has required classes to become multimodal in order to teach students the skills required in the 21st-century work environment. [34] However, in the classroom setting, multimodality is more than just combining multiple technologies, but rather creating meaning through the integration of multiple modes.
