Connecting the Basics: Understanding Networking Hubs
Networking hubs are among the earliest devices used to build local area networks (LANs). They act as a central connection point where multiple computers or network-enabled devices can connect and communicate. Although modern networks often rely on switches and routers, networking hubs still play a role in basic or educational environments where simplicity and low cost matter.
How Networking Hubs Work
A networking hub operates at the physical layer of the OSI model. When one connected device sends data, the hub receives the signal and broadcasts it to all other connected devices. This means every device on the hub gets the same data, regardless of whether it is the intended recipient. Because of this broadcasting behavior, hubs are less efficient and less secure compared to switches.
