In network cabling, what does the term "hub" refer to?

In network cabling, the term "hub" refers to a central connection point for devices. This device acts as a common junction where multiple network devices, such as computers, printers, and servers, can connect to communicate with one another within a Local Area Network (LAN). Hubs operate at the physical layer of the OSI model and serve to transmit data packets to all connected devices, regardless of the intended recipient. This is essential for establishing network connectivity and facilitating communication within the network.

Understanding the role of a hub is crucial, as it lays the groundwork for grasping more complex networking concepts and devices, including switches and routers, which can manage data traffic more efficiently by directing data to specific devices rather than broadcasting it to all.
