*Tree topology combines the characteristics of bus topology and star topology.
*A tree topology is a type of structure in which all the computers are connected with each other in hierarchical fashion.
*The top-most node in tree topology is known as a root node, and all other nodes are the descendants of the root node.
*There is only one path exists between two nodes for the data transmission. Thus, it forms a parent-child hierarchy.
Advantages of Tree topology
*Support for broadband transmission: Tree topology is mainly used to provide broadband transmission, i.e., signals are sent over long distances without being attenuated.
*Easily expandable:
We can add the new device to the existing network. Therefore, we can say that tree topology is easily expandable.
*Easily manageable:
In tree topology, the whole network is divided into segments known as star networks which can be easily managed and maintained.
*Error detection:
Error detection and error correction are very easy in a tree topology.
Limited failure: The breakdown in one station does not affect the entire network.
*Point-to-point wiring:
It has point-to-point wiring for individual segments.
Disadvantages of Tree topology
*Difficult troubleshooting: If any fault occurs in the node, then it becomes difficult to troubleshoot the problem.
*High cost: Devices required for broadband transmission are very costly.
*Failure: A tree topology mainly relies on main bus cable and failure in main bus cable will damage the overall network.
*Reconfiguration difficult: If new devices are added, then it becomes difficult to reconfigure.
