6. Consider the case where a prospective buyer faxes an enquiry
letter to a seller requesting the price of some goods. The
components of this one-way communication process are:
•the prospective buyer (sender)
•the seller (receiver)
•a request for the price of goods (information)
•text (form of information)
•fax (medium)
In a two-way communication, the receiver sends feedback, i.e.
responding information, to the sender. On receiving the
feedback from the receiver, the sender may send further
information to the receiver
17. Channels refer to the forms of communication, e.g. written and oral
communication.
Media are the means for carrying the information, e.g. letters and
memorandums.
