In a network topology, which arrangement forms a single linear path with devices connected in a line?

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

Answer: (B)

A bus topology is defined by a single backbone cable that runs in a line with devices connected along it, forming one straight path. Data travels along that shared cable in either direction, and terminators at the ends prevent signal reflections. This linear arrangement—devices tapping into one continuous cable—is what characterizes the setup.

Why this fits: the essential feature is the one-line backbone with devices on that same line, not a closed loop, a centralized star, or multiple interconnections. A ring forms a closed loop with each device linked to two neighbors, a star centers on a hub or switch with devices branching out, and a mesh has multiple pathways between devices for redundancy.
