- Virtual local area network (VLAN): A grouping of network nodes in a logical domain

The purpose of a VPN is to provide the same safeguards and security that a directly wired connection should provide. A VLAN creates a logical arrangement of network nodes, regardless of their proximity, into a single domain structure. A VLAN is a virtual subset of a network that is...
