A tree topology is described as:

A tree topology is described as:

• A. A single linear connection
• B. A hybrid of star and bus topologies
• C. A network designed exclusively for local-area connections
• D. A completely self-contained network

Answer: (B)

A tree topology is defined as a hierarchical structure that combines characteristics of both star and bus topologies. This arrangement features a central "root" node connected to multiple "branch" nodes, which further extend to other nodes, somewhat resembling a tree's branches. The star aspect comes from the connections that cluster around a central point (the root), while the bus element reflects the linear nature of the connections that extend outwards in increments. In this configuration, data can flow along these branches like in a bus topology, while the individual nodes communicate with the central node, similar to how devices connect in a star topology. This hybrid structure enhances scalability since adding or removing nodes is relatively straightforward without disrupting the entire network. Hence, the description of tree topology being a hybrid of star and bus topologies is accurate because it retains elements from both structures to facilitate organized, hierarchical networking.
