A Full-Duplex communication system's primary advantage lies in its ability to facilitate simultaneous two-way communication. This means that both parties in the communication can send and receive messages at the same time, significantly increasing the efficiency and speed of the interaction.

This capability is particularly beneficial in applications like telephone calls or video conferencing, where participants engaged in a conversation need to exchange information without waiting for the other party to finish speaking. With Full-Duplex, there is no need for complicated turn-taking protocols, which are necessary in half-duplex systems where communication is one-directional at any given time.

In contrast, the advantages related to cost, power consumption, or simplicity of implementation are often not as pronounced in Full-Duplex systems. These factors vary based on the technologies used, and media employed rather than being inherent benefits of Full-Duplex communication itself. Thus, the key takeaway is that the main strength of Full-Duplex is its efficiency in allowing real-time, two-way interaction.
