Show answer & explanation
Correct answer: B. Star
Explanation
In a Star topology, every node is individually connected to a central device (a hub or switch) that relays all traffic between nodes; the network depends on this central point. Bus topology uses a shared common backbone with no central controller, mesh topology connects nodes directly to each other, and ring topology connects nodes in a closed loop — none of these require a central hub.More Data Communication and Computer Networks questions
