Virtual LAN (VLAN)

A Virtual Local Area Network (VLAN) is a way to create separate, logical groups within a larger computer network, even if they share the same physical hardware. Think of it like different departments in a company using the same building but having their own private areas. VLANs improve security and organization by isolating traffic, ensuring that sensitive information stays within specific groups, and reducing congestion. They are configured through network switches to segment the network efficiently without the need for additional physical devices, providing flexibility in managing and controlling network connections.
