VLAN (Virtual Local Area Network)

A Virtual Local Area Network (VLAN) is a technology that allows you to create separate, logical networks within a single physical network. Imagine a large office where employees from different departments work together but need their own secure communication channels. VLANs enable this by grouping devices into distinct networks, even if they share the same physical infrastructure. This improves security, reduces congestion, and allows for easier network management, as each VLAN acts as its own mini-network with unique access controls and settings, making it easier to organize and protect data within an organization.
