Correct answer: A
CONCEPT
A network topology is identified from the pattern of links between nodes. A star has one central connection point, a ring forms a closed loop, and a bus uses one shared backbone line.
APPLICATION
Diagram I shows every outer node connected directly to the central Host, so it represents topology 3, the star network.
Diagram II connects each node to two neighbours in one closed loop, so it represents topology 1, the ring network.
Diagram III connects the nodes to a single shared communication line, so it represents topology 2, the bus network.
CROSS-CHECK
Diagram | Visible structural clue | Topology |
|---|---|---|
I | Central host with radial links | 3 — Star network |
II | Closed loop of neighbouring nodes | 1 — Ring network |
III | Single shared communication line | 2 — Bus network |
Therefore, the matching is I–3, II–1 and III–2.
