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.
