The term "hub" is most commonly associated with which of the following?

Concept

A network topology describes how nodes and links are arranged. In a star topology, each end device has a separate link to one central connecting device, often called a hub or switch.

Application

Here, "hub" is being used in the topology sense. A star network places the end devices around a central connecting device, so the required answer is "A star network."

Contrast

• A ring network arranges nodes in a closed loop, with links between neighbouring nodes.

• A router is a network-layer device that forwards packets between IP networks.

• A bridge is a data-link-layer device that connects LAN segments.

Cross-check

In the described arrangement, removing the central connecting device disconnects all spokes. That is the defining connectivity pattern of a star topology.
