The one who receives the message.

3. Message - 

The information or data which is sent by the sender. It has the address of the receiver. Ex - Text, numbers, pictures, audio, video, etc.

4. Transmission Medium - 

The transmission medium is a connection between the sender and receiver, and it carries the message to be transmitted. Example - twisted-pair wise, fiber-optical cable, microwaves, radio waves, etc.

5. Protocol - 

Both the parties or devices agree on a set of rules to conduct data communication. Communication never occurs between a person who understands only Sanskrit and a person who understands only English.

If both will agree on the same language then communication will occur. This is called Protocol.
