switch is Network devices operating at Layer 2 or The data link layer of the OSI model. They connect devices in a network and use packet switching to send, receive, or forward packets or data frames across the network. Switches have many ports into which computers plug into.

Where is the switch in the network?

The network switch can be in either OSI Layer 2 (Data Link Layer) or Layer 3 (Network Layer). Layer 2 switches forward data based on the destination MAC address (as defined below), while Layer 3 switches forward data based on the destination IP address. Some switches can do both.
