Extended Star 1 Ring

Tree ¹⁸⁰ is the topology that is similar to the extended star topology. The primary difference is that it does not use one central node. It uses a trunk node from which it branches to other nodes. There are two types of tree topologies: the binary tree (each node splits into two links) and the backbone tree (a backbone trunk has branch nodes with some links hanging from it). The trunk is a main wire that has several layers of branches. From a logical perspective, the flow of information is hierarchical.
