Which topology uses a central hub to connect all devices?

  • Bus
  • Ring
  • Mesh
  • Star
Correct Answer: D. Star

Detailed Explanation

Star topology is the type of network where all devices are connected to a central hub or switch. It is one of the most common and simple network setups used in homes and offices.


  • Bus: All devices share one cable

  • Ring: Devices are connected in a circular path

  • Mesh: Every device connects to every other device

  • Star: All devices connect to a central hub



In star topology, the hub controls communication. If one device fails, the rest of the network keeps working. But if the hub fails, the whole network goes down.
