Network Topologies
A topology refers to both the physical and logical layout of a network. The physical topology of a network refers to the actual layout of the computer cables and other network devices. The logical topology of a network, on the other hand, refers to the way in which the network appears to the devices that use it.
Several topologies are in use for networks today. Some of the more common include the bus, ring, star, mesh, and wireless topologies. The following sections provide an overview of each.
