Shannon and Weaver's Communication Model has five basic factors. The factors in this model are:
 The information source selectsa desired message
 The transmitter changes the message into a signal that is sent over the communication channel to the receiver.
 The receiver changes the transmitted signal back into a message,and interpreting this message.
 Then, this message is sent to the destination. The destination may be another receiver or the message may rest with the initial receiver, and the transmission isachieved.
