Virtual LAN
In data communications and networking, a Virtual LAN is a group of network services not restricted to a physical segment, a LAN switch, or even a Dedicated Server. Virtual LANs logically segment switched networks based on the functions, project teams, or applications of the organization regardless of the physical location or connections to the network just like in a Cloud Hosting or Website Hosting as its application. All workstations and servers used by a particular workgroup share the same VLAN, regardless of the physical connection or location.
Configuration or reconfiguration of VLANs is done through software. Physically connecting or moving cables and equipment is unnecessary when configuring VLANs. It consists of hosts or networking equipment connected by a single bridging domain. The bridging domain is supported on different networking equipment.
