What does VLAN stand for?

VLAN stands for Virtual Local Area Network. This term reflects a networking technology that allows network administrators to create a single logical network encompassing multiple physical networks. By utilizing VLANs, devices on the same network can communicate as if they were on the same physical LAN, regardless of their actual physical location. This segmentation enhances network security and performance by isolating broadcast traffic, improving management, and facilitating the organization of devices based on functional or departmental divisions rather than physical layout.

The other definitions provided, while they may contain some familiar terms, do not accurately describe the technical specification or use of VLANs in networking. Understanding the purpose and functionality of VLANs is integral to network design and management, particularly in complex environments where efficient communication and security are paramount.
