Re: Tree Topology

Definition :

A tree topology combines characteristics of linear bus and star topologies. It
consists of groups of star-configured workstations connected to a linear bus
backbone cable (See fig. 3). Tree topologies allow for the expansion of an
existing network, and enable schools to configure a network to meet their

Advantages of Tree Topology

1. It is an extension of Star and bus Topologies, so in networks where these
topologies can't be implemented individually for reasons related to
scalability, tree topology is the best alternative.

2. Expansion of Network is possible and easy.

3. Here, we divide the whole network into segments (star networks), which
can be easily managed and maintained.

4. Error detection and correction is easy.

5. Each segment is provided with dedicated point-to-point wiring to the
central hub.
6. If one segment is damaged, other segments are not affected.

Disadvantages of Tree Topology

1. Because of its basic structure, tree topology, relies heavily on the main
bus cable, if it breaks whole network is crippled.

2. As more and more nodes and segments are added, the maintenance
becomes difficult.

3. Scalability of the network depends on the type of cable used.
