Which topology connects all devices to a central hub?

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

Answer: (C)

A star topology connects all devices to a central hub or switch, which acts as the traffic dispatcher. Each device has its own direct link to the hub, so all communication goes through that central point to reach other devices. This setup is easy to manage and faults can be isolated to a single link, but the hub itself is a single point of failure. Other topologies don’t center all devices on one hub: mesh adds many interconnections between devices, ring links devices in a loop, and bus uses a single shared backbone cable. Because everything routes through a central hub, this topology best matches the description.
