What term transmits and receives signals in one unit?

• A. Transceiver
• B. Datalink
• C. Radio Frequency Interference
• D. Carrier Wave

Answer: (A)

A transceiver is a device that both transmits and receives signals in one unit. In many communication systems, including drone remotes and radios, this single hardware package handles sending out a signal and listening for responses or data, making it the perfect fit for a setup described as one unit that can do both directions of communication.

Datalink refers to the method or path by which data is transferred, not to a single device that handles both sending and receiving. RF interference is noise that can disrupt signals, not a device. A carrier wave is the basic oscillating signal that carries information, but it’s not a piece of equipment by itself that performs both transmitting and receiving.
