local area network
(gcide) | LAN \LAN\ n. [Local Area Network.]
A local area network; a network[3] connecting computers and
word processors and other electronic office equipment within
a small area, to create an inter-office system, typically
within one building or one site of a corporation. Contrasted
to WAN, a wide-area network.
Syn: local area network.

LAN
(LAN) A data communications network which is
geographically limited (typically to a 1 km radius) allowing
easy interconnection of terminals, microprocessors and
computers within adjacent buildings. Ethernet and FDDI
are examples of standard LANs.
Because the network is known to cover only a small area,
optimisations can be made in the network signal protocols that
permit data rates up to 100Mb/s.
See also token ring, wide area network, {metropolitan area
network}..

VLAN
(VLAN) A logical grouping of two or more nodes
which are not necessarily on the same physical {network

LAWN
WiLAN
WLAN
(WLAN /W-lan/, or "LAWN" /lorn/, sometimes
"WiLAN" /wi-lan/) A communication system that transmits and
receives data using modulated electromagnetic waves,
implemented as an extension to, or as an alternative for, a
wired LAN. WLANs are typically found within a small
client node-dense locale (e.g. a campus or office
building), or anywhere a traditional network cannot be
deployed for logistical reasons.
Benefits include user mobility in the coverage area, speed and
simplicity of physical setup, and scalability. Being a
military spin-off, WLANs also provide security features such
as encryption, frequency hopping, and firewalls. Some
of these are intrinsic to the protocol, making WLANs at
least as secure as wired networks, and usually more so. The
drawbacks are high initial cost (mostly hardware), limited
range, possibility of mutual interference, amd the need to
security-enable clients.
The established protocols are covered by {IEEE 802.11
(http://standards.ieee.org/getieee802/)}. Recent developments
include the Bluetooth project and other WPAN, or {Personal
Area Network} initiatives, accessible through {IEEE 802.15
working group (http://grouper.ieee.org/groups/802/15/)}.
