FDDI and MAN Flashcards
(12 cards)
What does FDDI stand for in networking?
FDDI stands for Fibre Distributed Data Interface. It is a standard for high-speed data transmission in a local or metropolitan area network over fiber optic cables.
What type of topology does FDDI use?
FDDI uses a dual-ring topology, which provides redundancy. If one ring fails, data can still travel through the second ring in the opposite direction.
What is the data transfer speed of FDDI?
FDDI can transfer data at speeds up to 100 Mbps, which was considered very fast at the time it was developed.
What is the maximum distance supported by FDDI?
FDDI can support distances up to 200 kilometers, making it suitable for MANs (Metropolitan Area Networks).
Why is FDDI considered reliable?
FDDI is reliable because of its dual-ring topology, which ensures network continuity even if one ring is broken or damaged.
What is a Metropolitan Area Network (MAN)?
A MAN is a network that spans a city or large campus, interconnecting multiple LANs. It provides high-speed connectivity and is larger than a LAN but smaller than a WAN.
How does a MAN differ from a LAN?
A MAN covers a larger area than a LAN, often a whole city, and typically connects multiple LANs using high-speed backbone links like fiber optics.
What technologies are commonly used in MANs?
Technologies used in MANs include FDDI, Ethernet, ATM (Asynchronous Transfer Mode), and newer optical fiber systems.
Who typically owns and operates MANs?
MANs are often operated by ISPs, telecom companies, or large organizations that need to connect multiple buildings or campuses in a city.
What are common applications of MANs?
MANs are used in universities, government buildings, hospitals, and corporate campuses to link together LANs and provide centralized services.
What are the advantages of using fiber optics in FDDI and MANs?
Fiber optics offer high speed, long distance transmission, immunity to electromagnetic interference, and greater security.
What is the role of FDDI in MAN implementation?
FDDI provides the high-speed, reliable backbone required to interconnect LANs in a metropolitan area, forming the core of a MAN.
