What is an example of full duplex communication?

Full duplex communication refers to a mode of communication where data can be sent and received simultaneously between two devices. This means that both devices can transmit and receive messages at the same time without having to pause or wait for the other to finish transmitting. This capability enhances the efficiency of communication and is commonly seen in technologies such as telephone calls, where both parties can speak and hear each other at the same time.

In contrast, the other options represent different communication methods: one device sending data and waiting for an acknowledgment describes a half-duplex or simplex mode of communication where one device must wait for confirmation before sending more data. Communicating at different times indicates a waiting period between transmissions, which is also characteristic of half-duplex communication. Lastly, transmitting data in bursts pertains to the timing of data flow rather than the ability for simultaneous communication in both directions. Thus, option C is the embodiment of full duplex communication, effectively illustrating its definition and application.
