VLANs provide ease of network management and are implemented to achieve scalability and security. They can quickly adapt to changes in network requirements and relocation of workstations and server nodes. A virtual local area network is a logical group of workstations, network devices and servers that appear to be on the same LAN despite their physical location. A VLAN allows a network of computers and users to communicate in a pseudo environment as if they exist in a single LAN and are sharing a single broadcast domain.
