What is the functional difference between Token Ring Token Bus and FDDI?

There are no purely functional differences between a token ring token bus implementation and FDDI. In fact, the token bus is defined in IEEE 802.4, and FDDI's topology derives from that very standard. Think of FDDI as being a subset of 802.4. Refer to RFC 1042 (http://www.faqs.org/rfcs/rfc1042.html) for more details.
The remainder of my entry doesn't really apply to this question and is more subjective, but I do try to outline some other non-functional differences between the two standards.
Apart from functional differences, the obvious ones can be broken into a couple different parts off the top of my head: physical and application. The physical difference is that Token Ring pretty much uses coax cable as its medium while FDDI conspicuously uses fiber. From an application standpoint, Token Ring is short distance (coax has a maximum attenuation distance of 500 meters) while FDDI can traverse far greater distances while attaining greater throughput. As a result, FDDI would be much more scalable, supportive of many more users, and primarily used in large geographically-demanding environments but pricey; on the other hand, token ring would be for less scalable environments but cheaper.
Another non-functional difference would be noise immunizations. FDDI is inherently immune to most interferences that coax implementations would be heir to. Fluorescent lighting, various frequencies, and other causes of noise to fiber would not affect it in the same adverse manner that would apply to coax.

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.
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.
What is the fddi access method?
token passing
What is the difference between fddi-i and fddi-ii?
FDDI 1 vs FDDI 2Fiber Distributed Data Interface (FDDI) is a data transmission standard for Local Area Networks (LAN) which uses fiber optic lines. A FDDI LAN can extend up to 200 kilometers and it can support thousands of users. The FDDI 1 protocol is based on the token ring protocol. FDDI 2 is an extended version of FDDI. It extends FDDI by adding capability to handle voice and video signals.Difference between FDDI 1 and FDDI 2 (FDDI ii)FDDI-2 is the second generation protocol of FDDI. The key difference between them is that, in addition to all the functionality FDDI provides, FDDI-2 provides the ability to handle voice signals and video. Even though both FDDI and FDDI-2 runs at 100 Mbits/sec on the fiber and transport asynchronous and synchronous types of frames, FDDI-2 can transport isochronous traffic using the newly developed hybrid mode. Further, FDDI and FDDI-2 stations can be operated in the same ring only in the basic FDDI mode
What is the transmission speed of token ring and FDDI?

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.
What are the advantages of FDDI over token ring?
Although they both use a rotating ring setup, the FDDI uses two to achieve better results and less chance of failure. FDDI also uses a timed protocol that leads to differences in frame format and how station traffic is controlled.
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 technologies use token passing method and a physical star but logical ring topology?
token ring uses a physical star and a logical ring ,while FDDI uses a physical star/ring and a logical ring.
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
