A virtual LAN (VLAN) is a local area network with a definition that maps workstations on some basis other than geographic location (for example, by department, type of user, or primary application).

A VLAN is a group of PCs, servers, and other network resources that behave as if they were connected to a single network segment, even though they might not be. For example, all marketing personnel might be spread throughout a building. Yet if they are all assigned to a single VLAN, they can share resources and bandwidth as if they were connected to the same segment. The resources of other departments can be invisible to the marketing VLAN members, accessible to all, or accessible only to specified individuals, depending on how the IT manager has set up the VLANs. 306

Virtual Local Area Networks (VLANs)
A local area network (LAN) can generally be defined as a broadcast domain. Hubs, bridges,
or switches in the same physical segment or segments connect all end node devices. End
nodes can communicate with each other without the need for a router. Routers connect
LANs together, routing the traffic to the appropriate port.
A virtual LAN (VLAN) is a local area network with a definition that maps workstations on
some basis other than geographic location (for example, by department, type of user, or
primary application). To enable traffic to flow between VLANs, traffic must go through a
router, just as if the VLANs were on two separate LANs.
A VLAN is a group of PCs, servers, and other network resources that behave as if they were
connected to a single network segment, even though they might not be. For example, all
marketing personnel might be spread throughout a building. Yet if they are all assigned to a
single VLAN, they can share resources and bandwidth as if they were connected to the same
segment. The resources of other departments can be invisible to the marketing VLAN
members, accessible to all, or accessible only to specified individuals, depending on how the
IT manager has set up the VLANs.
