What does the term "full duplex" mean in communication systems?

• A. The ability to send and receive signals simultaneously
• B. The ability to transmit data at a single frequency
• C. The capability of recording multiple audio tracks
• D. The process of encoding and decoding signals

Answer: (A)

The term "full duplex" in communication systems refers to the ability to send and receive signals simultaneously. This means that both parties in a communication channel can transmit and receive information at the same time without interference. Full duplex systems are often seen in voice communications, such as telephones, where both users can speak and listen at the same time, enhancing the flow of conversation and improving the overall user experience. In contrast, other options do not align with the definition of full duplex. For instance, the ability to transmit data at a single frequency pertains more to modulation techniques or frequency allocation, rather than the simultaneous transmission and reception aspect. The capability of recording multiple audio tracks relates to audio production and not the real-time communication aspect characteristic of full duplex systems. Similarly, encoding and decoding signals is a fundamental process in data transmission but does not specifically address the simultaneous transmission of data inherent in a full duplex operation.
