Tree topology is one of the most common network setups that is similar to a bus topology and a star topology. A tree topology connects multiple star networks to other star networks.
Advantages:
Advantages:
- The tree topology is useful in cases where a star or bus cannot be implemented individually. It is most-suited in networking multiple departments of a university or corporation, where each unit (star segment) functions separately, and is also connected with the main node.
- The advantages of centralization that are achieved in a star topology are inherited by the individual star segments in a tree network.
- Each star segment gets a dedicated link from the central bus. Thus, failing of one segment does not affect the rest of the network.
- Fault identification is easy.
- The network can be expanded by the addition of secondary devices. Thus, sociability is achieved.
- As multiple segments are connected to a central bus, the network depends heavily on the bus. Its failure affects the entire network.
- Owing to its size and complexity, maintenance is not easy and costs are high.
- Though it is salable, the number of nodes that can be added depends on the capacity of the central bus and on the cable type.
