A logical topology is how devices appear connected to the user. A physical topology is how they are actually interconnected with wires and cables. For example, in a shared Ethernet network that ...

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.

"What we've found is that topology is a powerful resource for information encoding in the presence of noise," says Professor Andrew Forbes from the Wits School of Physics. Quantum entanglement is ...
