VLAN (Virtual Local Area Network) is a logical group of devices within a network that are grouped together based on their function or location, rather than their physical connectivity. VLANs allow network administrators to segment networks for security, organization, and efficiency purposes. Devices in different VLANs can communicate with each other through routing or Layer 3 switches. VLANs help reduce broadcast traffic and improve network performance by limiting the scope of broadcasts to a specific group of devices. Additionally, VLANs can be used to control access to resources and applications based on user roles and permissions.
