A tree topology (hierarchical topology) can be viewed as a collection of star networks arranged in a hierarchy. This tree has individual peripheral nodes which are required to transmit to and receive from one other only and are not required to act as repeaters or re-generators. The tree topology arranges links and nodes into distinct hierarchies in order to allow greater control and easier troubleshooting. This is particularly helpful for colleges, universities and schools so that each of the connect to the big network in some way.
Advantages of Tree Topology
- Point-to-point wiring for individual segments.
- Supported by several hardware and software vendors.
- All the computers have access to the larger and their immediate networks.
Disadvantages of Tree Topology
- Overall length of each segment is limited by the type of cabling used.
- If the backbone line breaks, the entire segment goes down.
- More difficult to configure and wire than other topologies.
6. Hybrid Topology
A combination of any two or more network topologies. A hybrid topology always accrues when two different basic network topologies are connected. It is a mixture of above mentioned topologies. Usually, a central computer is attached with sub-controllers which in turn participate in a variety of topologies.
Advantages of Hybrid Topology
- It is extremely flexible.
- It is very reliable.
Disadvantages of Hybrid Topology
- Expensive to develop & maintain
