Token Ring naturally uses the ring architecture. A mesh topology is usually found in a wide area network (WAN) to provide redundant paths between locations. See Ethernet and Token Ring.

the whole network fails if the switch fails as no node can communicate a wired star topology requires plenty of cable - in a large network this can be expensive Star topologies tend to be found in ...

Figure 1: Network topology: biochemical reaction scheme versus causal connectivity. In cells, two main types of networks can be distinguished on the basis of their mode of action: gene networks ...
