VLAN

A Virtual Local Area Network or VLAN is a logical subdivision of a network. A VLAN in general corresponds to a single subnet, a broadcast domain, and to a network segment.

VLANs can be configured within a switch, and can be assigned to access ports as well as to trunk ports. Frames that belong to specific VLANs have an 802.1Q tag that includes the VLAN ID of the VLAN to which it belongs.
