Linear Model
Shannon and Weaver first developed this model of communication in the late 1940s. Their model contains six elements: a source, encoder, message, channel, decoder, and receiver. The information source begins with the message. Then, the encoder uses a channel to devlier the message to the reciever who will decode the message. In the channel, it is possible for noise to affect the transmission of the message. This process is one sided, and the encoder will only serve as the encoder until a new message is transmitted.
