Virtual LAN (VLAN)

A virtual local area network (VLAN) is used to logically group or segment systems within a single LAN, letting them communicate as if they were on a separate LAN. This setup happens by using a router to segment the network or by using switches that support the creation of VLANs, allowing multiple devices to be grouped and treated as if they were all on the same network.

What Small and Midsize Businesses Need to Know About Virtual LAN (VLAN)

Businesses can benefit from a VLAN because it lets them group systems together based on their needs. For example, a company could create a VLAN for its sales department and another for its marketing department. This grouping would allow the two departments to communicate without interfering or taking bandwidth from the rest of the network. It would also help protect sensitive data by keeping it separate from other systems.
