WebA network switch is equipment that allows two or more IT devices, such as computers, to communicate with one another. Connecting multiple IT devices together creates a communications network. Compute, print, server, file storage, Internet access, and other IT resources can be shared across the network. WebWhen a switch receives an Ethernet packet, it stores the sending device's MAC address and the port it is connected to in a locally held table called a MAC address table. The switch process then checks the MAC address table to see if the destination MAC address is connected to the same switch. polyhydramnion definitionWebFeb 18, 2024 · Layer 2 vs Layer 3 switches.
