Information SourceThe Source All human communication has some source(information source in Shannons terminology), some person orgroup of persons with a given purpose, a reason for engaging incommunication. Youll also find the terms transmitter andcommunicator used.
Transmitter (aka Encoder)Once the purpose of the source has beendecided, there must be a specified format forthe message to take. This is what thetransmitter (encoder) does; it takes the conceptthat the source wants sent out, and puts it into asuitable format for later interpretation.
ChannelIt is essential for meaningful communicationthat a suitable means to transmit the messagebe selected. The channel is the route that themessage travels on, be it verbal, written,electronic, or otherwise.
Noise SourceIt is inevitable that noise may come intoplay during the communication process.Noise could be considered an interferenceor distortion that changes the initialmessage; anything that can misconstrue themessage may be noise. Noise can bephysical, as in an actual sound that mufflesthe message as it is being said, or it can besemantic, like if the vocabulary used withinthe message is beyond the knowledgespectrum of its recipient.
ReceiverIn order for communication to be executed,there must be a second party at the end of thechannel the source has used. The receiver takesin the message that the source has sent out.
DestinationThe intended audience to themessage.
FeedbackFeedback relates to the source whethertheir message has been received, andmost importantly, if it has beeninterpreted accurately. Withoutfeedback, the source would never knowif the communication was successful.Ongoing communication is made possibleby the cyclical route feedback allows; ifmore communication between the twoparties is necessary, they can follow themodel indefinitely.Sorry whatwas that?
