Network Topology
The way a network is configured is called the network topology. Topology can refer to a
physical or a logical view of the network. For example, physical topology describes the
actual network cabling and connections, while logical topology describes the way the
components interact. It is important to understand the distinction, because a specific
physical topology might be able to support more than one logical topology. For example,
it is not uncommon to run cabling in a certain pattern because of physical installation
and cost issues, but to use a different pattern for the logical topology.
The workstations in Figure 10-33 on the next page are arranged in a circular shape,
but that might or might not reflect the network topology. The examples shown in
Figures 10-34 to 10-38 on pages 478 to 481 represent a logical topology, as seen by network
users, who do not know or care about the physical cabling pattern.
