Tree topology is a type of network design that looks like a tree with branches connecting different devices in a structured way. It is made by combining bus topology and star topology, which gives it both strength and flexibility. Learn what tree topology means in computer networking, programming, and data structures. See examples of tree topologies, such as star bus, binary trees, and B-trees. What is Tree Topology? Tree topology, also referred to as hierarchical topology, is a network structure where each node is interconnected in a hierarchical manner, resembling the branches of a tree. Learn what tree topology is, how it works, and its advantages and disadvantages. See different types of tree topologies and examples of networks that use them.
