In a full duplex setup, which feature is enhanced over half duplex?

In a full duplex setup, simultaneous transmission and reception is a key feature that distinguishes it from half duplex. In a half duplex configuration, communication can occur in both directions, but not at the same time; data can either be sent or received, but not both simultaneously. This can lead to delays and a reduction in the overall efficiency of the communication process, as the channel must switch between sending and receiving modes.

In contrast, full duplex allows devices to send and receive data simultaneously, which effectively doubles the potential bandwidth utilization. This means that devices can communicate more efficiently, leading to better performance, especially in environments where high data throughput is necessary.

This enhancement in communication capability directly impacts applications that require real-time data exchange, such as video conferencing or online gaming, where the ability to transmit and receive data at the same time is crucial for maintaining fluid and continuous interaction. The other options, while relevant to networking, do not represent the primary advantage of full duplex over half duplex in terms of communication efficiency.
