What Is a Switch? - Kaashiv Infotech Networking
In computer networking, a switch is a device that connects multiple devices within a local area network (LAN). It uses MAC addresses to identify each device and intelligently forward data only to the intended recipient. This makes switches faster and more efficient than hubs, which broadcast data to every device in the network. Switches operate mainly at Layer 2 (the Data Link Layer) of the OSI model, but some advanced models—called Layer 3 switches —can perform routing functions as well. Whether in small offices or large enterprise systems, switches play a critical role in managing data flow and minimizing congestion. What Is a Switch? - Kaashiv Infotech Networking
