Hub-and-Spoke topology is a network design where multiple devices (spokes) connect to a central hub, which manages communication.

Elaboration:

• The hub acts as a central point for all connections.
• Used in VPNs, airline reservation systems, and enterprise networks.
• Easier to manage but suffers from a single point of failure.

Example:

A corporate VPN where branch offices (spokes) connect to a central headquarters (hub).
