What does FDDI stand for in networking?

FDDI stands for Fiber Distributed Data Interface, making this choice the correct answer. FDDI is a standard for data transmission in a local area network that uses optical fiber as its primary transmission medium. It can transmit data at rates of 100 Mbps and is designed for high-speed communication over long distances, making it a crucial technology in network architecture.

The term "distributed" in FDDI indicates its topology, which supports a network configuration where data can be accessed by multiple devices that are connected across a shared medium. This enhances the network’s reliability and fault tolerance. The choice of "fiber" underscores the technology's reliance on optical fibers for signal transmission, which helps to greatly reduce electromagnetic interference and allows for higher data rates over longer cable runs compared to traditional copper cabling.

Other options reflect different misinterpretations of the FDDI acronym. For instance, "Digital" rather than "Distributed" changes the meaning and context, while "Device Interfacing" does not align with the standard definition. The correct understanding of FDDI is essential for anyone studying networking principles, particularly those related to local area networks and optical communication technologies.
