What is ethernet fddi?
standard for data transmission in a local area network that can extend in range up to 200 kilometers (124 miles). Although FDDI logical topology is a token ring network, it does not use the IEEE 802.5 token ring protocol as its basis; instead, its protocol is derived from the IEEE 802.4 token bus timed token protocol. In addition to covering large geographical areas, FDDI local area networks can support thousands of users. As a standard underlying medium it uses optical fiber, although it can use copper cable, in which case it may be refer to as CDDI. FDDI uses a dual-attached, counter-rotating token ring topology.FDDI was considered an attractive campus backbone technology in the early to mid 1990s, but FDDI has since been effectively obsoleted by fast Ethernet and, since 1998, by Gigabit Ethernet due to their speed, lower cost, and ubiquity.FDDI, as a product of American National Standards Institute X3T9.5 (now X3T12), conforms to the Open Systems Interconnection (OSI) model of functional layering of LANs using other protocols. FDDI-II, a version of FDDI, adds the capability to add circuit-switched service to the network so that it can also handle voice and video signals. Work has started to connect FDDI networks to the developing Synchronous Optical Network SONET.A FDDI network contains two token rings, one for possible backup in case the primary ring fails. The primary ring offers up to 100 Mbit/s capacity. When a network has no requirement for the secondary ring to do backup, it can also carry data, extending capacity to 200 Mbit/s. The single ring can extend the maximum distance; a dual ring can extend 100 km (62 miles). FDDI has a larger maximum-frame size than standard 100 Mbit/s Ethernet, allowing better throughput.Designers normally construct FDDI rings in the form of a "dual ring of trees" (see network topology). A small number of devices (typically infrastructure devices such as routers and concentrators rather than host computers) connect to both rings - hence the term "dual-attached". Host computers then connect as single-attached devices to the routers or concentrators. The dual ring in its most degenerate form simply collapses into a single device. Typically, a computer-room contains the whole dual ring, although some implementations have deployed FDDI as a Metropolitan area network

How is a FDDI network like a Token Ring network How is it different?
Both Token Ring and FDDI use the concept of a ring topology structure. However, Token Ring is used in a LAN, and FDDI is used in a MAN.Token Ring is implemented with copper cable (UTP cable) and FDDI uses Fiber Optic cable.Finally, the protocols are very different between the two. FDDI uses a synchronous type of transmission, where Token Ring uses an actual token (a 3 character packet) to control who has access to transmit or receive on the network. FDDI does not use this technique.
How do you spell FDDI?
The acronym FDDI stands for Fiber Distributed Data Interface, which provides enhanced data transmission in a local area network.
What is difference between fddi and 802.5 token ring?
Fddi can be further connected to other networks whereas token ring is individual network of computers.
What is fddi nic?
Fiber Distributed Data Interface (FDDI) NICs are commonly used to connect host systems or file servers to FDDI network equipment using one connectin (single attachment) and to attach the network equipment to the FDDI cabling through two attachments (dual attachment). FDDI is defined by the ANSI X3T9.5 standards committee and provides an access method to enable high-capacity data throughput on busy networks. It has a data throughput rate of 100Mbps, and is simliar to the token ring access method because it uses token passing for network communication.
Which network architecture can automatically correct for cable failures?
Token Ring and FDDI networks can.
What speed does FDDI use?
FDDI (Fiber Distributed Data Interface) operates at a speed of 100 Mbps (megabits per second). It utilizes a dual-ring architecture for redundancy, allowing data to be transmitted in both directions. This design helps maintain network reliability and performance, even in the event of a failure in one of the rings. FDDI is primarily used for high-speed networking in local area networks (LANs) and can support long-distance connections.
Is FDDI a ring netwok?
FDDI is a dual-ring structure, usually found in MANs (metropolitan area networks). Although it has a physical ring structure it is not the same as a token ring network.
