VLAN stands for Virtual Local Area Network. VLAN is a logical grouping of network users and resources connected to a switch. By default, all switches make up a large broadcast domain in the layer-2 switched network. By creating VLAN, we could break up broadcast domains into smaller ones within a switch by assigning different ports of the switch into different subnets. The benefits of using VLAN include broadcast control, security, flexibility, scalability, etc.
