Which network topology has nodes that cooperate to relay data to ensure connectivity among all nodes?

• A. Star Network
• B. Mesh Network
• C. Ring Network
• D. Bus Network

Answer: (B)

Cooperation among devices to relay data and keep every node reachable defines a mesh topology. In a mesh, each node can connect to multiple neighbors, and routing is dynamic so messages can be forwarded through various paths. This redundancy means if one link or node fails, data can still find an alternate route, preserving connectivity across the entire network. This differs from a star setup, where every device talks to a central hub and the network relies on that single point. In a ring, nodes form a closed loop and traffic travels around the circle, which can be broken if a link fails. In a bus, all devices share a single communication line, so a fault on that line can disrupt the whole network. The described behavior—nodes working together to relay data to ensure everyone stays connected—fits mesh topology best.
