Virtual Local Area Network (VLAN)

IT Infrastructure and Networking

A Virtual Local Area Network (VLAN) is a networking technology that logically segments a single physical network into multiple isolated virtual networks, improving security, traffic management, and organization without requiring separate physical infrastructure. Network administrators use VLANs to separate departments, devices, or traffic types (like voice versus data) within a business, reducing broadcast traffic and enhancing control over network access. Configuring VLANs typically involves managed switches and tagging protocols like IEEE 802.1Q.
