Switches and VLANS

A switch is a networking device that connects devices within a local area network (LAN) and facilitates communication between them. It primarily operates at Layer 2 (Data Link Layer) of the Open Systems Interconnection (OSI) model, though some switches, known as multilayer switches, can also operate at Layer 3 (Network Layer).
