What is Tree Topology in Computer Networking

Network topology in which the nodes are placed in the form of a tree. From a topological view, the tree connection is similar to a series of interconnected star networks except that it does not have a central node. Instead, it has a trunk link node, usually occupied by a hub or switch, from which the other nodes branch. It is a variation of the bus network, the failure of a node does not imply interruption in communications. The same communications channel is shared.

Tree Topology is Combination of Star:

The tree topology can be seen as a combination of several star topologies. Both the tree and the star are similar to the bus when the interconnection node works in broadcast mode, since the information is propagated to all stations, only in this topology the branches extend from a root point ( star), as many branches as possible, depending on the characteristics of the tree.

Advantages and Disadvantages of Tree Topology:

Every topology has it's own uniqueness, beside the uniqueness there are some pros of tree topology and some cons of tree topology described below. Having something in mind tell us in comments.

Advantages of Tree Topology:

  1. Multiple devices can be attached because of secondary hub. A signal can able to travel to distance because of central hub device.
  2. Tree Topology is one of the best alternative to apply other topologies in real life.
  3. Tree topology enables the differentiated services to prioritize communication between devices. e.g. computers attached to one secondary hub can be given priority over others.
  4. Differentiated service enables not to wait for the access of network while sharing Time Sensitive Data.
  5. Advantages are mostly similar to the Star Topology in computer networking.
  6. The Error detection are easy and correction therefore may easy.
  7. Each computer is connected with point to point wiring or connection to central hub.

Disadvantages of Tree Topology:

  1. Main bus cable are used so tree topology is not reliable because it depends on bus cable. If the main cable or bus cable breaks the network will shutdown or slow.
  2. Maintenance mode will be difficult for this network because more nodes added to it.
  3. Difficulty in adding more nodes because it depends on cable used.
