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 ...
A physical topology is how they are actually interconnected with wires and cables. For example, in a shared Ethernet network that uses hubs rather than switches, the logical topology appears as if ...
Bus network topologies are used when a small, cheap and often temporary network is needed that does not rely on very high data-transfer speeds. They may be used in locations such as a laboratory ...
