Which term represents the unit that both transmits and receives signals in one housing?

• A. Datalink
• B. Transceiver
• C. Carrier Wave
• D. Noise

Answer: (B)

A transceiver is the unit that both transmits and receives signals in one housing. In radio communications, it includes both the transmitter and the receiver in a single device, often switching between sending and listening so two‑way communication can happen efficiently. This is common in drone systems where the control link must send commands and receive status or video data through the same hardware framework. The other terms don’t fit: a datalink refers to the overall communication channel or system, not the single hardware box; the carrier wave is the radio wave that carries the information, not the device itself; and noise is unintended interference that corrupts signals.
