Which statement accurately describes a mesh network?

A mesh network is characterized by every node connecting directly to multiple other nodes. This structure allows for enhanced reliability and redundancy, as data can take multiple paths through the network. This decentralized nature means that if one node fails or a route becomes unavailable, the remaining nodes can still communicate with one another through alternative paths. This connectivity improves the overall resilience of the network, making it particularly useful in environments where continuous connectivity is essential.

The other options describe different network architectures. For instance, stating that all nodes connect to a single hub refers to a star topology, which centralizes data flow through one central point. Arranging nodes in a linear configuration describes a bus topology, where devices are connected to a single cable line. Finally, a centralized network structure, where a central server or node manages resources and communications, contrasts sharply with the decentralized nature of a mesh network. Thus, the statement regarding every node connecting to multiple other nodes is the defining feature that accurately describes a mesh network.
