The tree topology combines the characteristics of linear bus and star topology. It consists of groups of star configured work stations connected to a linear bus backbone cable. The tree topology allows for the expansion of ten existing network and enables organization to configure a network to meet their needs.
- In network where star and bus topology are not implemented for the reasons related to scalability, tree topology is the best alternative.
- Here we divide the network into segments which can be managed and maintained.
- Error detection and correction is easy in each segment but it is difficult to detect fault if the backbone cable is damaged
- Each segment is provided a dedicated point to point wiring to the central hub. If one of the segments is damaged, the others are not affected by this damage.
- If the back bone cable is damaged the entire network is crippled.
- As more and more nodes and segments are added, maintenance becomes difficult
- Scalability of the network depends upon types of cable used.
