Tree Topology. Among all the Network Topologies we can derive that the Tree Topology is a combination of the bus and the Star Topology. The tree like structure allows you to have many servers on the network and you can branch out the network in many ways.
Topologies are either physical or logical. There are four principal topologies used in LANs. These topologies can also be mixed. For example, a bus-star network consists of a high-bandwidth bus, called the backbone,which connects a collections of slower-bandwidth star segments.
