An example of a communication channel is face to face conversation, which carries the message between people.

The channel is the medium or route through which a message travels from sender to receiver.

Noise is a disturbance that distorts the message, not a channel that carries it.

Context is the setting or environment of the exchange, distinct from the medium itself.

Feedback is the receiver's return response, not the path along which the message moves.

Speech, writing, telephone and email are other common communication channels.
