Virtual LAN (VLAN)

Summary

A Virtual LAN (VLAN) is a subnetwork that can group together devices from different physical LANs, allowing them to communicate as if they were on the same physical network.

Detailed Description

VLANs are used to partition a single switched network into multiple logical networks, which improves performance and security. Each VLAN is treated as a separate broadcast domain. Devices within the same VLAN can share resources, such as printers and servers, regardless of their physical location. VLANs can be configured using network switches and routers and are identified by a unique VLAN ID number.
