Guide to Understanding and Examining Tree Topology

Tree topology, also known as a hierarchical topology, is one of the most important concepts in the CompTIA Network+ certification.
It combines the characteristics of linear bus and star topologies. It contains a root node and every other node connects directly to it forming a hierarchy. This is crucial because it allows computers in a network to have multiple points of connection, boosting their resilience and flexibility.
To understand this working, imagine a company with different departments; each department would have its own star topology network. However, these separate networks will connect to a single, common bus (root node), thus forming a tree network.
How to answer questions regarding Tree Topology in an exam:
Questions on this subject will basically revolve around its concept, structure, and characteristics. Understand the advantages (scalability and easy partitioning) and disadvantages (heavy dependency on main cable and difficult maintenance). Use this understanding to tackle related questions.
Exam Tips:
Remember that tree topology is a hybrid topology. Knowing its similarities and differences when compared to other topologies will provide a clear edge in your responses.
