Hub: A network device that connects multiple computers or other network segments. In a hub-based network, the hub receives data packets and broadcasts them to all connected devices, regardless of the intended recipient. Hubs operate on the Physical Layer of the OSI model and have been largely replaced by smarter, more secure switches.
