answer is given below.
A tree topology is a combination of a star network topology and a bus topology. In tree topology, nodes of the underlying bus network topology are replaced with a complete star topology.
There are certain special cases where tree topology is more effective:
Communication between two networks
A network structure which requires a root node, intermediate parents node, and leaf nodes (just like we see in an n-tree) or a network structure which exhibits three level of hierarchy because two level of hierarchy is already displayed in the star topology.
Advantages of tree topology:
Scalable as leaf nodes can accommodate more nodes in the hierarchical chain.
A point to point wiring to the central hub at each intermediate node of a tree topology represents a node in the bus topology
Other hierarchical networks are not affected if one of them gets damaged
Easier maintenance and fault finding
Disadvantages of tree topology:
Huge cabling is needed
A lot of maintenance is needed
backbone forms the point of failure.
