They incorporate technologies such as FDDI, DSL (digital subscriber line), satellite, and microwave communications
FDDI networks can be up to 124 miles (200 kilometers) in length
Similarities between LANS and WANS is that they are both networks and can cover small geographical areas.
Fddi can be further connected to other networks whereas token ring is individual network of computers.
Token Ring and FDDI networks can.
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
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.
WAN ( Wide Area Network )
Types of networks - including LANs, WANs and WLANs
The 802.11 wireless networks provide wireless access on a local network that generally covers a small area. Cellular WANS, meanwhile, are designed to cover city-wide and even global areas.
That is fiber optic cable, as FDDI stands for Fiber Distributed Data Interface
it is mainly used in FDDI protocol and USB
