The shape of a
local-area network (LAN) or other communications system. Topologies are either
physical or
logical.
There are four principal topologies used in LANs.
These topologies can also be mixed. For example, a bus-star network consists of a high-bandwidth bus, called the backbone, which connects a collections of slower-bandwidth star segments.
