Question

Quizplus · Accepted Answer

Frame relay is a packet-switched technology designed to connect local area networks (LANs) and transfer data across a wide area network (WAN). It operates at the physical and data link layers of the OSI model and is designed for carrying data traffic over public and private networks. IEEE 802.5 and IEEE 802.3 are standards related to token ring networks and Ethernet, respectively, and not specifically designed for packet switching over public data networks.
