Short Bytes: Tree Topology derives its roots from bus and star topology. Even though a tree topology is not so commonly used network topology, it is still followed in certain circumstances when scalability or hierarchical communication setup is needed between two networks.
In Tree Topology, all the computer are connected like the branches of a tree. In Computer Networking, tree topology is known as a combination of a Bus and Start network topology. The main advantages of this topology are better flexibility and scalability.
Tree network topology is the simplest topology in which only one route exists between any two nodes on the network. The pattern of connection resembles a tree in which all branches spring from one root hence (Tree Topology).
Characteristics of Tree Topology
- Ideal if nodes are located in groups.
- Used in Wide Area Network.
- Better Flexibility
- Better Scalability
Tree Topology integrates the characteristics of Star and Bus topology. In our previous article, we saw how in Star Topology, computers are connected by each other through the central hub. And we also saw in Bus Topology, Computers are connected by the common cable called Bus. After understanding these two network configurations, we can easily understand the working and construction of tree topology.
In Tree Network, the number of Star networks are connected using Bus. This main cable seems like the main route of a tree, and other star networks as the branches. It is also called Expanded Star Topology. The diagram below will illustrate that.
