<networking> (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.

<networking> (VLAN) A logical grouping of two or more nodes which are not necessarily on the same physical {network segment} but which share the same IP network number. This is often associated with switched Ethernet. IEEE 802.1Q is a VLAN standard. [Confirm? Better description? Reference?] (2002-08-30)

<networking> (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/)}.

A local area agreement (LAA) in the UK is a 3-year agreement between central government and a local area working through its Local Strategic Partnership. It contains a set of improvement targets which local organisations are committed to achieving and a delivery plan setting out what each partner is intending to do to achieve those targets.

Crescendo Networks, Ltd. was a privately held computer networking company headquartered in Sunnyvale, California with regional offices in EMEA and APAC.

A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage. SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from servers so that the devices appear to the operating system as direct-attached storage.
