Explanation
VLANs (Virtual Local Area Networks) logically divide a single physical network into multiple isolated broadcast domains without requiring separate physical hardware. This segmentation improves security by separating sensitive traffic (e.g., finance, HR, guest Wi-Fi) so that devices in one VLAN cannot directly communicate with another without going through a router or firewall. VLANs do not minimize collision domains (that is done by switches in general), do not provide cloud resource access, and do not increase IP address space.
