CompTIA Network+ (N10-009)Networking ConceptsEasy
A small office wants to connect five workstations so that each device connects to exactly two neighboring devices, forming a closed loop where data travels around the circle. Which topology is being described?
- AStar topology
- BBus topology
- CFull mesh topology
- DRing topology
Show answer & explanationAnswer & explanation
Correct answer: D. Ring topology
A ring topology connects each device to exactly two neighbors, forming a closed loop where data travels sequentially around the ring until it reaches its destination.
Why the other options are wrong
- A. Star topology connects every device to a central hub or switch, not to two neighbors.
- B. Bus topology uses a single shared backbone cable, not a closed loop.
- C. Full mesh connects every device to every other device directly.
Ring Topology
A network layout where each device connects to exactly two other devices, forming a continuous closed loop for data transmission.
- Each node has exactly two neighbors
- Data travels in one or both directions around the loop
- A single break can disrupt the entire ring unless dual-ring redundancy exists
Memory trick: Picture a circle of friends passing a note hand to hand — that's a ring.
