What does FDDI stand for in networking terminology?

FDDI stands for Fiber Distributed Data Interface. It is a standardized network protocol that specifies the physical and media access control layers of the data link layer, allowing for high-speed data transmission over fiber optic cables. FDDI was developed in the 1980s and can support data rates of up to 100 Mbps, making it suitable for connecting LANs (Local Area Networks) and providing backbone connectivity.

The importance of FDDI lies in its ability to maintain a robust network infrastructure, featuring dual counter-rotating rings for redundancy. This design enhances reliability, as the network can continue operating even if one ring fails. FDDI has been instrumental in supporting high-traffic environments, especially before the widespread adoption of other technologies such as Ethernet over twisted pair cables.

The other choices reflect plausible yet incorrect interpretations of what FDDI represents. They deviate from the established definition and terminology used in networking standards.
