What is a defining feature of mesh topology?

Mesh topology is characterized by the presence of numerous connections between network nodes. In a mesh network, each node can communicate with one another directly or via multiple other nodes, creating a web-like structure that allows for alternative pathways for data transmission. This feature enhances reliability and redundancy, as the failure of one connection doesn't necessarily disrupt the overall communication flow.

In contrast, the other options represent different network topologies. A single connection between all nodes describes a star topology, where all nodes connect to a central hub. A ring topology indicates a circular arrangement where each node connects to exactly two other nodes, forming a continuous loop. Lastly, a linear connection pattern is characteristic of bus topology, where all devices share a single communication line. Understanding these distinctions helps clarify why numerous connections are crucial in defining mesh topology, making it suitable for environments where high reliability and performance are essential.
