Multiple Choice

A communication link that can send and receive information at the same time is described as which?

The main idea is that the link can send and receive at the same time. That capability is called full-duplex. In a full-duplex connection, transmitting and receiving occur concurrently, so two parties can talk and listen simultaneously—like a telephone call. By contrast, simplex means one-way only, and half-duplex means two-way communication but not at the same moment—you must take turns. WDM is about using multiple wavelengths to carry signals on the same fiber, a multiplexing technique, not the directional capability of the link. So the description of a link that can send and receive simultaneously best matches full-duplex.
