How is tree topology different from bus topology?

Tree topology is a hierarchical structure where multiple branches can each have one or more basic topologies, such as ring, bus, or star. In this type of network, data transmitted from the source first reaches the centralized device, and from there, the data passes through every branch where each branch can have links for more nodes.

In bus topology, each communicating device connects to a transmission medium known as a bus. Data sent from a node are transmitted along the length of the bus in both directions. As a result, data can be received by any of the nodes connected to the bus.
