What does it mean for a network to be full-duplex?

A full-duplex network refers to a communication system where data can be transmitted in both directions simultaneously. This means that two devices can send and receive information at the same time without causing interference, much like a two-way street where traffic flows in both directions at once. This capability enhances the efficiency of communication over the network, allowing for more fluid interactions and reducing wait times for devices needing to exchange information.

In contrast, options describing one-directional data flow or limitations in packet size do not apply to full-duplex systems. Additionally, the idea of double speed does not define full-duplex; it simply refers to the ability to communicate bi-directionally rather than the speed of data transmission itself. Thus, the characteristic of simultaneous bidirectional communication is what truly defines a full-duplex network.
