What is tree topology? Advantage and disadvantage of tree topology

 THREE TOPOLOGY...

Tree topology is a topology which is having a tree structure in which all the computer are connected like the branches which are connected with the tree! 
In computer network tree topology is called as a combination of a bus and start network topology. The main advantage of this topology are these are very flexible and also have better scalability. Network topology is the systemically arrangement of the elements of a communication network.network topology can be used to make understand that it is the arrangement of various types of telecommunications network which includes command and control radio network.

Advantage of tree topology

1) This topology is the combination of bus and start topology.
2) this topology provide a hierarchical as well as central data arrengement of the node.
3) As the leaf node can add one or more nodes in the hierarchical chain this topology provide high scalability.
4) the other node is a network are not affected if one of their nodes get damages or not  working
5) tree topology provide easy maintenance and easy fault identification can be done
6) A cable topology leaf nodes can held more nodes
7) supported by several hardware and software vendors
8) point to paint wiring for individual segment.

Disadvantage of tree topology

1) this network is very difficult to configure as compared to the other networks topology.
2) lenght of  a segment is limited and the limit of the segment depends on the type of cabling used.
3) due to the presence of large number of nodes the network performance of tree topology become a bit slowly 
4) if the computer in first level is erroneous next level computer will also go under problem
5) required large number of cables compared to start and ring topology
6) As the data need number of cables compared to start and ring topology.
7) as data need to travel from the central cable this creates dense network.
8) treatment of the topology is pretty complex.
