Which topology is described as a single cable that connects all devices with two endpoints?

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

Answer: (A)

Think about a single wire that runs the length of the network and into which every device taps. that setup is a bus topology. The key feature is a single cable with two ends, terminated at both ends to prevent reflections. Data travels along that shared path; every node can see the transmissions, but only the intended recipient processes the frame while others ignore it. This matches the description of one cable connecting all devices with two endpoints.

A ring, by contrast, is a closed loop with no ends, so it doesn’t use a single trunk cable. A star uses individual cables from each device to a central hub, not one shared line. A mesh involves multiple direct links between devices, rather than a single backbone. So the described topology is bus.
