What Is Tree Topology : The tree topology structure takes its name from the fact that the central node acts as a network’s trunk, with nodes branching outward in a branch-like pattern. Whereas each node in a star topology is directly connected to the central hub, the nodes in a tree topology are connected in a parent-child hierarchy. Those connected to the central hub are connected to other nodes in a linear fashion, thus two connected nodes have only one mutual connection. The tree topology structure is frequently used for wide area networks to handle many spread-out devices since it is both incredibly flexible and scalable. The linking of multiple devices can be done like tree branches in a tree network structure. These topologies are commonly used to connect the computers in a corporate network. There is only one link between any two connected nodes in this topology since these two nodes have only one mutual connection, resulting in a regular parent-child hierarchy.
This sort of topology is also known as a star bus topology in computer networks, because it combines the features of both a star and a bus topology. This type of topology is more successful in specific situations, such as communication between two networks. Different nodes, such as root, lead, and intermediate, are required for the network’s structure. There are three types of tree network topologies: bus tree, spanning tree, and cluster tree.

Applications of Tree Topology:
The following are some of the applications of tree network topology.
Tree topology is mostly used to recognise a system over a network in order to distribute data across the network and to allow network operators to add several servers. This is the optimal network topology since signals are sent through the root nodes and received by all machines at the same time.
Database systems like PostgreSQL, MySQL, and Redis, as well as file systems like HFS+, Ext4, and NTFS, all use these topologies.
Tree Topology Examples:
this topology are extensively used in business networks to organise data in databases and workstations. Any two linked nodes in a tree network can only have one mutual connection, hence there can only be one link between them.
Tree topology advantages and disadvantages:

Advantages of Tree Topology:
The following are some of the benefits –
This network topology is a hybrid of two topologies, such as star and bus.
Because leaf nodes can add more nodes to the hierarchical chain, it has a high scalability.
If one of the network’s nodes is damaged, the rest of the nodes are unaffected.
It is simple to identify and maintain faults.
It is supported by a variety of software and hardware providers.
Within the hierarchical sequence, scalable nodes, such as leaf nodes, can include more nodes.
Every centre node of this architecture has point-to-point wiring to the middle hub, indicating a node inside the bus topology.
Better scalability and flexibility.
Disadvantages of Tree Topology:
The following are some of the drawbacks-
In comparison to other topologies such as star and bus, it necessitates extensive wiring.
It is necessary to perform routine maintenance.
Once a hub breaks, the entire network will fail.
This network’s configuration is not simple.
In a this topology structure, the health of the root node is as important as it is in a star topology structure. The numerous node branches will become disconnected if the central hub fails, yet communication within—but not between—branch systems would persist.
Adding extra nodes to a tree topology can quickly become an awkward, not to mention pricey, experience due to the hierarchical complexity and linear structure of the network layout. Because of the vast amount of wiring necessary to link each device to the next within the hierarchical layout, this topologies are costly.
