| W3C |
W3C (World Wide Web Consortium) is an international consortium founded in 1994 that unites over 450 organizations involved with the Internet and the World Wide Web. Its purpose is to
"lead the World Wide Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability". The W3C develops and publishes open standards for the web. |
|
| WAN |
| WAN (Wide Area Network) is a telecommunications network that covers a large area, such as a state or country, spanning multiple LANs. The term often suggests the inclusion of public (shared user) networks. |
|
| WAP |
WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that handheld wireless devices (PDAs, cell phones, pagers, two-way radios) can interoperate and be used for Internet access, including Web, e-mail, Web, newsgroups, IRC, etc.
Also: Wireless Access Point (WAP or AP) - a device, essentially a base station that connects wireless devices together to create a wireless network by transmitting/receiving radio signals. A WAP is usually also connected to a wired network, and can relay data between devices on each side. |
|
| Wardriving |
Wardriving is the practice of searching for Wireless LAN (WLAN) signals within a geographic area. It often refers to driving around looking for wireless networks. The term was coined by Pete Shipley. It's a concept taken from the movie "WarGames", where the actor dials many phone numbers looking for computers to access, called "War-Dialing". Other similar terms include war-walking, war-flying, etc. refering to the modes of transportation used for moving around to identify various wireless Access Points.
With many wireless networks being 'plug and play' right out of the box, we are witnessing a tremendous amount of networks that are simply wide open to intrusion. Drive down a city street with just a laptop, a wireless card, and a program such as Netstumbler. You will come across dozens of open networks from which you can access the internet, and potentially the files of the other computers on the network. |
|
| WDM |
WDM (Wavelength Division Multiplexing) is a type of multiplexing used in optical fiber. WDM modulates each of several data streams onto a different part of the light spectrum.
See also: TDM, FDM. |
|
| WDS |
| WDS (Wireless Distribution System) is a Wireless Access Point mode that enables wireless bridging in which WDS APs communicate only with each other (without allowing for wireless clients or stations to access them), and/or wireless repeating in which APs communicate both with each other and with wireless stations (at the expense of half the throughput). |
|
| WebDAV |
WebDAV (Web distributed authoring and versioning) is an industry standard extension to the HTTP specification. WebDAV adds a capability for authorized users to remotely add and manage content on a web server.
For additional information, see RFC 2518. |
|
| WEP |
WEP (Wired Equivalent Privacy) is IEEE security protocol, specified in the Wi-Fi (Wireless Fidelity, or 802.11b) standard. WEP is designed to provide a WLAN (Wireless Local Area Network, a.k.a LAWN ;) ) with a level of security and privacy comparable to what is usually expected of a wired LAN, by encrypting data transmitted over the WLAN.
Although WEP provides some level of security, there has been some controversy whether it lives up to being equivalent to that of wired LANs. Either way, WEP should always be used in conjunction with all other traditional security practices. In 2001, a fast WEP cracking algorithm was discovered, coming from capturing enough "weak IV" frames, something that occurs randomly. Manufactures have since altered the algorithm to not use weak IVs in most devices -- this technology is sometimes known as WEP-plus.
When entering WEP keys manually, note the following guidelines:
- One ASCII character is 8 bits, one Hex character is 4 bits.
- 64 (or 40) bit WEP code has 5 ASCII or 10 HEX characters.
- 128 (or 104) bit WEP code has 13 ASCII or 26 HEX characters. |

| Wi-Fi |
Wi-Fi (short for "Wireless Fidelity,") is a term used generically when referring to any type of 802.11 network, such as 802.11b, 802.11g, or 802.11a.
Wi-Fi uses DSSS, and is comparable to Ethernet in functionality. While most Wi-Fi connections are between a mobile device and an access point, it is also possible to create an "ad-hoc" network directly among two or more devices, without an access point.
All Wi-Fi product using the same radio frequency (for example, 2.4GHz for 802.11b & 802.11g, 5GHz for 802.11a) are designed to work with each other. Also, 802.11g products are backward compatible with 802.11b devices, since they use the same 2.4GHz frequency.
Note: Wi-Fi is a trademark of the Wi-Fi Alliance, a nonprofit industry association. The IEEE technical specification for Wi-Fi is 802.11. |
|
| WiMAX |
WiMAX (Worldwide Interoperability for Microwave Access) is a wireless telecommunication technology based on the IEEE 802.16 standard, which allows for high-speed wireless data transmission over long distances.
The name WiMAX was created by the WiMAX Forum, which was formed in June 2001 to promote conformance and interoperability of the standard.

| Windows 9x |
Windows 9x/ME - "A 32 bit extension and graphical shell, for a 16 bit patch to an 8 bit operating system, originally coded for a 4 bit microprocessor, written by a 2 bit company, that can't stand 1 bit of competition."
Note: Sense of humor required. |
|
| WISP |
| WISP (Wireless Internet Service Provider) is an ISP that allows subscribers to connect to a server at designated access points using a wireless connection such as Wi-Fi. This type of ISP offers broadband service and allows subscriber computers, called stations, to access the Internet and the Web from anywhere within the zone of coverage provided by the server antenna(s). |
|
| WLAN |
WLAN (a wireless LAN) is a type of LAN that uses high-frequency radio transmissions (rather than cables) to communicate between network nodes.
Also reffered to as "LAWN" :) |
|
| WLL |
| WLL (Wireless Local Loop) is a term for the use of a wireless communications link as the "last mile" connection for delivering plain old telephone service (POTS) and/or broadband Internet to telecommunications customers. Various types of WLL systems and technologies exist. |
|
| WML |
| WML (Wireless Markup Language) is a tag based language similar to HTML, used to create web pages that can be delivered using WAP to handheld wireless devices. WML is tailored for the smaller display size of such devices, and requires less memory and processing power than HTML and Javascript. |
|
| WMM |
WMM (Wi-Fi Multimedia) is a wireless QoS specification, a subset of 802.11e improving quality of video and voice applications for wireless clients.
It can help control latency and jitter when transmitting multimedia content over a wireless connection. |
|
| WMM |
| WMM (Wi-Fi Multimedia, formerly known as Wireless Multimedia Extensions - WME), is a Wi-Fi Alliance certified feature based on the IEEE 802.11e standard. This feature provides QoS to wireless networks. It is especially suitable for voice, music and video applications; for example, Voice over IP (VoIP), video streaming, and interactive gaming. |
|
| worm |
worm is a separate computer program that can replicate itself automatically over a network.
Worms are ofren, but not always, malicious and might interfere with the normal use of a computer or a program. They often exploit vulnerabilities in some automatic file sharing feature found on many computers to replicate.
Worm is different than a virus, it does not alter/infect files and its main ability is to replicate by itself. Still, a malicious worm can be programmed to delete all your files just as well. |
|
| WPA |
WPA (WiFi Protected Access) is a wireless standard designed to improve upon the security features of WEP. It is designed to work with existing WiFi products (as a software upgrade to existing WEP-capable hardware).
The two improvements over WEP are:
1. Improved data encryption through TKIP (temporal key integrity protocol), which hashes/scrambles the keys and adds an iintegrity-check, ensuring the keys haven't been tampered with.
2. User authentication through EAP (extensible authentication protocol).
WPA takes two forms; WPA Enterprise Mode and WPA Personal, or PSK (Pre-Shared Key) Mode. WPA PSK is somewhat more vulnerable to attacks: a cracker passively intercepting initial key exchange messages can then possibly crack poorly chosen short passphrases with a robust dictionary attack offline and without access to the network.
WPA-Enterprise is an encryption method that protects unauthorized network access by verifying network users through a server.
WPA-Personal is an encryption method that protects unauthorized network access by utilizing a set-up password.
Note: WPA is an interim standard being replaced with the IEEE’s now ratified 802.11i standard, branded WPA2. |
|
| WPA2 |
WPA2 is the follow up to the Alliance's interim security plan, WPA (Wi-Fi Protected Access). WPA2 is based on the ratified IEEE 802.11i standard, and provides government grade security by implementing the NIST FIPS 140-2 compliant AES encryption algorithm. WPA2 provides network administrators with a high level of assurance that only authorized users can access the network.
WPA2 can be enabled in two versions — WPA2 - Personal and WPA2 - Enterprise. WPA2 - Personal protects unauthorized network access by utilizing a set-up password. WPA2 - Enterprise verifies network users through a server. WPA2 is backward compatible with WPA.

| WYSIWYG |
WYSIWYG (What You See Is What You Get, pronounced "wizzy-wig") refers to software that displays what your work will look like while you're creating it.
Sometimes also WYSINQWYG ;) (What You See Is Never Quite What You Get, pronounced "wizzin-quig"). |
