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.
Network topologies are categorized into the following basic types: bus; ring; star; tree; mesh; More complex networks can be built as hybrids of two or more of the above basic topologies.
