Hybrid topology is the interconnection of two or more basic topologies, each of which is laid out so the resulting network does not display a standard topology. Two examples of a hybrid-type network are the star bus network and star ring network. The term "topology" references the layout pattern of the connected devices, or the interconnections of computers, networks and links.
A hybrid topology always forms in the instance two different basic network topologies are connected. One common example, the star ring network, is made up of at least two topologies that are linked by utilizing a multi-station access unit, or MAU, as the centralized hub. A star bus network is made up of two or more topologies as well, but the topologies are connected by a bus trunk.
Network topology is classified as logical or physical. Logical topology refers to the transference of data within a network, while physical topology defines the network's design. Devices, cable installation and location are included in a physical topology's schematics.
Physical topology is associated with the core network while logical topology uses basic protocols for transferring information. As a result, physical topology concerns itself with the installation of the devices, while logical topology is connected to how the information is conveyed.
