VLAN (Virtual Local Area Network)

What is a VLAN?

A VLAN (Virtual Local Area Network) is a logical subnet that is created within a physical network. It enables the separation of device groups that are physically located in the same network without the need for additional hardware such as separate switches. VLANs increase security and efficiency by isolating and limiting data traffic.

Advantages and possible applications

VLANs improve network security by separating sensitive data and devices. They facilitate the management of large networks and enable better control of data traffic. VLANs are widely used in corporate networks, data centers and educational institutions, where they help to optimize network infrastructure and comply with security policies.
