What does VLAN stand for?

VLAN stands for Virtual Local Area Network. This term is used in networking to describe a logical subgroup within a local area network (LAN). VLANs help segment networks for improved performance, security, and organization. By creating separate VLANs, network administrators can control traffic flow, reduce congestion, and enhance security measures by isolating sensitive data or departments without requiring physical separation of devices.

The correct choice accurately captures the full term and its meaning in the context of network architecture. The other options, while they may sound plausible, do not represent the standard definition or usage of VLANs in networking terminology.
