A networking device used to connect multiple computers and devices in a LAN. A switching hub (switch) is commonly used in wired LANs to consolidate cable connections and is required when building a small in-office network. Simple hubs broadcast incoming data to all ports, while switches selectively forward data to the appropriate destination port.
