Star 1 Tree

Extended star is the topology that exists for the expansion of a star. An extended star topology has a core star topology with each of the end nodes of the core topology acting as the center of its own star topology. The advantage of this is that it keeps wiring runs shorter and limits the number of devices that need to interconnect to any one central node. It is the most widespread type of connection both in LAN and in the WAN. From logical point of view, an extended star topology is very hierarchical ¹⁷⁹ and information is encouraged to stay local.
