Definition, advantages and disadvantages of Tree Topology
Tree topology is the combination of Bus and Star topology. Here the central workstation or the hub of the Star topologies is connected to the main Bus, along which various Star topologies are placed via their central workstation. If any particular workstation or the node is disrupted, then it will get isolated without affecting the network. But if the central hub of the Star topologies goes down then the whole section of workstation related to it also goes down.
Multiple hubs can exist which can be connected to smaller nodes called roots in this case. This structure gives better performance as the main hub controls the whole network.
Advantages of Tree Topology
- It is most suitable for large networks where ring and star topologies are not efficient.
- Since it divides the network in sub-parts, so it becomes more manageable
- There is no hassle in either expanding or removing the nodes.
- For individual segments there is dedicated line wiring to the local hub.
Disadvantages of Tree Topology
- The network is vulnerable as it is wholly dependent on the central hub.
- If the network becomes extremely large it becomes difficult to manage.
