Trunk In telecommunications, a communications channel between two switching systems. In a
wireless network, a trunk is a wireless connection from one Access Point to
another.
Type of Service (ToS) Sometimes also called IP Precedence, ToS is a system of applying QoS
methodologies, based on headers placed into transmitted IP packets.
User Datagram Protocol (UDP) A connectionless protocol similar to TCP/IP, but without the
same level of error checking. UDP is commonly used when some small degree of
error and packet loss can be tolerated without losing program integrity, such as
for online games.
virtual LAN (VLAN) A local area network with a definition that addresses network nodes on some
basis other than physical location or even whether the systems are wired together
or operating using the same local equipment. VLANs are, on average, much
easier to manage than a physically implemented LAN. In other words, moving a
user from one VLAN to another is a simple change in software, whereas on a
regular LAN, the computer or device would need to be connected physically to a
different switch or router to accomplish the same thing. Network management
software of some sort is used to configure and manage the VLANs on a given
network.
Wired Equivalent Privacy (WEP) Security protocol for wireless local area networks (WLANs)
defined in the 802.11b standard. Uses dynamically or manually assigned keys for
encryption and authentication, as dictated by the capabilities of the client station.
The WEP algorithms are vulnerable to compromise; therefore, WEP security is
only recommended for legacy clients that do not support the newer generation
security standards.
Windows Internet Name Server (WINS) The Windows implementation of DNS, which maps IP
addresses to computer names (NetBIOS names). This allows users to access
resources by computer name instead of by IP address.
Wi-Fi A play on the term "HiFi," Wi-Fi stands for Wireless Fidelity, a term for wireless
networking technologies.
Wi-Fi Protected Access Wi-Fi Alliance-sponsored security solution that addresses many of the
WEP inadequacies. Originally promulgated as an interim solution, WPA is now
included as part of the IEEE 802.11i standard.
wireless local area network (WLAN) A type of local area network that employs radio
frequencies to transmit data (usually encrypted), much like LANs transmit data
over wires and fiber optic cables.
