Networks today are essential for supporting businesses, providing communication, delivering entertainment—the list goes on and on. A fundamental element networks have in common is the network switch, which helps connect devices for the purpose of sharing resources.

A network switch is a device that operates at the Data Link layer of the OSI model—Layer 2. It takes in packets being sent by devices that are connected to its physical ports and sends them out again, but only through the ports that lead to the devices the packets are intended to reach.
