व्याख्या :

A switching hub, also known as a network switch, is designed to send packets using package addresses. A network switch operates at the data link layer of the OSI model and uses MAC addresses to forward data frames to specific devices within a local area network (LAN). Unlike a hub, which simply broadcasts data to all devices in the network, a switch intelligently forwards packets only to the device intended to receive the data, increasing network efficiency and reducing unnecessary network traffic.
