VLAN (Virtual Local Area Network)
Virtual Local Area Networks (VLANs) are a network segmentation technique that allows multiple virtual networks to coexist on the same physical network infrastructure. VLANs enhance network security, improve performance, and simplify network management by segregating traffic based on criteria like function, department, or application. This separation reduces the risk of data breaches, minimizes network congestion, and enables more targeted and efficient deployment of network policies.
