Final answer:
Correct answer: A) Sender to receiver.
Step-by-step explanation:
A communication channel is the means by which messages are transmitted from a sender to a receiver in the process of communication. In the case of the human body, for instance, we have the nervous system and the endocrine system that communicate to control and coordinate actions. In a broader context, when we think about media, it involves various formats like television, radio, print, and the Internet, all of which are used to share information to the public broadly. These media act as a common carrier, providing a line of communication between the government and the people and vice versa.
In the context of your question, a communication channel conveys messages from the sender, who initiates the communication, to the receiver, who is the target of the message. To clarify the options you provided, the correct answer is: A) Sender to receiver.
This is because the encoder and decoder are components of the process where the message is transformed before transmission and then interpreted upon receipt, while the medium is what carries the message, and noise refers to anything that disrupts the clarity of the message during transmission.
