Corporate networks often use tree topologies, but they also often incorporate star topologies and an Intranet. Most home networks are configured in a tree topology that connects to the Internet. Typical network configurations include bus topology, mesh topology, ring topology, star topology, tree topology, and hybrid topology. It describes how many connections each device has, in what order, and what sort of hierarchy. Devices are represented as vertices, and their connections are represented as edges on the graph. The term network topology describes the relationship of connected devices in terms of a geometric graph.
