Chapter 3. Wireless Network Physical Architecture

3.1. Wired Network Topologies—A Refresher

The topology of a wired network refers to the physical configuration of links between networked devices or nodes, where each node may be a computer, an end-user device such as a printer or scanner, or some other piece of network hardware such as a hub, switch or router.

The building block from which different topologies are constructed is the simple point-to-point wired link between two nodes, shown in Figure 3.1. Repeating this element results in the two simplest topologies for wired networks—bus and ring.

For the ring topology, there are two possible variants depending on whether the inter-node links ...
