The document discusses communication processes and provides examples. It defines one-way communication as information being sent from a sender to a receiver with no feedback. An example given is a prospective buyer faxing an enquiry letter to a seller. Two-way communication allows the receiver to provide feedback to the sender by responding with further information. Channels refer to the form information takes, such as written or oral, while media are the means used to carry the information, like letters or electronic devices.
