Virtual Local Area | A VLAN consists of a network of computers that behave as if connected to the same wire, |
Network (VLAN) | though they may actually be physically connected to different segments of a LAN. VLANs |
| are configured through software rather than hardware, which makes them extremely |
| flexible. |
