This statement is false because the receiver is one of the fundamental elements of communication. In basic communication theory, a complete communication process requires at least four essential elements: the sender, the information or message content, the transmission medium or channel, and the receiver. If the receiver is missing, communication cannot be completed because there is no endpoint to accept, interpret, or respond to the transmitted information.
In datacom networks, this concept maps directly to real networking scenarios. A source host generates data, the data is carried over some medium such as copper, fiber, or wireless, and a destination host receives the data. Network devices such as switches and routers assist the forwarding process, but the fundamental communication model still includes both communicating endpoints. HCIA-Datacom emphasizes the complete sender-to-receiver process when introducing network communication basics, protocol encapsulation, and forwarding. Therefore, excluding the receiver from the communication elements is conceptually incorrect. The correct understanding is that sender, receiver, information content, and channel together form the essential basis of communication.
