Which of the following networking topologies uses a hub to connect computers?

Bus topology uses a single shared backbone cable to which all devices connect, with no central hub.

Ring topology connects each device to exactly two other devices forming a closed loop, with no hub.

In a star topology, every node has a dedicated point-to-point connection to a central hub or switch. This centralized design simplifies troubleshooting because a single cable failure only affects one device, not the entire network.

Cycle is not a recognized standard network topology in networking fundamentals.
