to a segment that is a single broadcast domain. Packets received in
one VLAN can only be forwarded within that VLAN.
VLAN allows the grouping of end stations logically, based not on
physical location but on business policies such as job function or
department. Members of a group can be dispersed throughout a
facility - they do not have to be connected in close physical
locations.
Hence, group members can coordinate their data communication
requirements regardless of the actual working locations; and the
logical network can extend to any point you want it to. Moreover,
VLAN groups can be modified at any time to add, move or change
users without any re-cabling.

VLAN Workgroup Application
Shared Server
The switch compliant to the IEEE802.1Q tagging VLAN standard
allows ports to exist in multiple VLANs for shared resources, such as
servers, printers, and switch-to-switch connections. It is also
possible to have resources exist in multiple VLANs on one switch as
shown in the following figure.
