VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by their
physical location and can communicate as if a common broadcast
domain, a LAN. The primary utility of using VLAN is to reduce
latency and need for routers, using faster switching instead. Other
VLAN utility includes:

Security, Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network because data will be switched
to only those confidential users within the VLAN.

Cost Reduction, VLANs can be used to create multiple broadcast
domains, thus eliminating the need of expensive routers.
Port-based (or port-group) VLAN is the common method of
implementing a VLAN, and is the one supplied in the Switch.
