Channel:

The further element in the process of communication is the channel through that the communication is transmitted. It connects the sender and the receiver. The most generally used channels are sight and sound. In an organisational environment, the channel could take the form of face-to-face conversation, written memos, group meetings, telephonic exchanges, etc. Outside the organisation, the channels could be letters or circulars, radio programmes, magazines, or TV shows, etc. For communication to be effective, the channel used should be appropriate for the message as well as the receiver. For an urgent message, telegram, telephone, fax, e-mail, etc. or radio would be the appropriate channel. As a power utility employee, you may like to communicate the duration of power cut. Which channel will you choose? Newspaper, radio or TV?
