Tree Topology:-

            It has a root node, and all other nodes are connected to it, forming a hierarchy. It is also called hierarchical topology. It should have at least three levels to the hierarchy.

Features of Tree Topology:-

  • It combines characteristics of linear bus and star topologies.
  • It is arranged in a group of star workstations connected to a linear bus backbone cable.
  • The top-level node in tree topology is known as a root node, and all other nodes are hierarchy of the root node.

Advantages of Tree Topology:-

  • Point-to-point connection of each computer is connected to each part of hub network.
  • It is easy to add computer by extending the cables to connect computers.
  • Error detection is an easy process.
  • Fast expansion of nodes.

Disadvantages of Tree Topology:-

  • If any faults occur in the node, it is difficult to maintain.
  • Requires high cost devices for broadband transmission.
  • If new or more nodes are added, then it becomes difficult to reconfigure.
  • Failure in the main bus cable will damage the overall network.
