VLANs

VLANs (Virtual Local Area Networks) are a way to segment a physical network into separate, isolated sections. Think of them like walls within a building, creating different rooms where specific groups of devices can communicate with each other securely, without interference from other groups. This improves security and organization, allowing administrators to control who can see and access data across different parts of the network. VLANs run on the same physical infrastructure but act as separate networks, making management more flexible and efficient without needing additional hardware.
