VLAN is a Virtual extension of LAN which works as a subnetwork for the collection of devices that communicate with one another within one logical network. The devices are physically apart but configured to communicate as if they are attached to the same wire. Implementing VLANs offers more flexibility than non-virtual network solutions and reduced security risks. It also helps in reducing traffic congestion as individual VLANs works as a separate LAN. Having a VLAN is cost-effective for organisations as it helps to expedite network operations and facilitates flexible teamwork.
