D) data-link

Question

Quizplus · Accepted Answer

Wide area networks typically use packet-switched technology, where data is divided into small packets and sent over the network using the most efficient route. This is in contrast to circuit-switched networks, where a dedicated circuit is established between two endpoints for the duration of the communication. Furthermore, store-and-forward refers to the practice of receiving and holding data packets until the entire message can be delivered in sequence, which is a common feature of packet-switched networks. Therefore, choice C, packet-switched, is the best answer.
