Which topology forms a ring where each device has two neighbors and the connections loop back?

• A. Ring Physical Topology
• B. Star Topology
• C. Bus Topology
• D. Mesh Topology

Answer: (A)

In a ring topology, each device connects to exactly two other devices, forming a circular path that loops back to where it started. This structure makes every node have two neighbors and creates a continuous loop for signals to travel around. Data typically moves around the ring in one direction (and might use a token to manage access), which is the hallmark of a ring layout. The other topologies don’t fit: a star relies on a central hub that all devices connect through, a bus uses a single shared backbone, and a mesh has many direct interconnections rather than one closed loop.
