Name Description
WAN Stands for "Wide Area Network." It is similar to a Local Area Network (LAN), but it's a lot bigger. Unlike LANs, WANs are not limited to a single location. Many wide area networks span long distances via telephone lines, fiber optic cables, or satellite links. They can also be composed of smaller LANs that are interconnected. The Internet could be described as the biggest WAN in the world.
WAP WAP stands for Wireless Access Point. A device that allows connectivity between computers with wireless network adapters to create a wireless network.
Watt A watt is an electrical unit measure that indicates the amount of electrical power on a circuit.
Web Browser: A Web browser, often just called a "browser," is the program people use to access the World Wide Web. It interprets HTML code including text, images, hypertext links, Javascript, and Java applets. After rendering the HTML code, the browser displays a nicely formatted page. Some common browsers are Microsoft Internet Explorer, Google Chrome, and Safari.
Web Page: Web pages are what make up the World Wide Web. These documents are written in HTML (hypertext markup language) and are translated by your Web browser. Web pages can either be static or dynamic. Static pages show the same content each time they are viewed. Dynamic pages have content that can change each time they are accessed. These pages are typically written in scripting languages such as PHP, Perl, ASP, or JSP. The scripts in the pages run functions on the server that return things like the date and time, and database information. All the information is returned as HTML code, so when the page gets to your browser, all the browser has to do is translate the HTML.
\n
\nPlease note that a Web page is not the same thing as a Web site. A Web site is a collection of pages. A Web page is an individual HTML document. This is a good distinction to know, as most techies have little tolerance for people who mix up the two terms.

Webcam: Webcams are typically small cameras that either attach to a user's monitor or sit on a desk. Most webcams connect to the computer via USB, though some use a Firewire connection. Webcams typically come with software that allows the user to record video or stream the video on the Web. If the user has a website that supports streaming video, other users can watch the video stream from their Web browsers.
\n 
\nWebcams can also be used for video chat sessions with other people. Instead of broadcasting the video on the Web, users can set up a video chat session with one or more friends and have a conversation with live audio and video. For example, Apple's iSight camera, which is built into Apple laptops and iMacs, allows users to video chat using the iChat instant messaging program. Several other chat programs also work with webcams, allowing users to set up video chat sessions with friends.

Website: A website, or Web site, is not the same thing as a Web page. Though the two terms are often used interchangeably, they should not be. So what's the difference? To put it simply, a Web site is a collection of Web pages.
WEP: Stands for "Wired Equivalent Privacy." WEP is a security protocol for Wi-Fi networks. Since wireless networks transmit data over radio waves, it is easy to intercept data or "eavesdrop" on wireless data transmissions. The goal of WEP is to make wireless networks as secure as wired networks, such as those connected by Ethernet cables.
Widget: Widgets are small programs designed for the Mac OS X Dashboard. Some widgets included with Mac OS X include a dictionary, calendar, weather forecast, and stock list widget. Several thousand other dashboard widgets are available from third-party developers.
Wi-Fi: Wi-Fi is a wireless networking standard trademarked by the Wi-Fi Alliance. It refers to all networking equipment that is based on one of the IEEE 802.11 standards. Wi-Fi allows computers and other devices to connect to wireless routers and therefore other systems on the network. If the router is connected to the Internet, devices connected to the wireless access point may also have Internet access.
Window: A window is an area on the screen that displays information for a specific program. This often includes the user interface GUI as well as the program content. Windows are used by most applications as well as the operating system itself. A typical window includes a title bar along the top that describes the contents of the window, followed by a toolbar that contains user interface buttons. Most of the window's remaining area is used to display the content.
Windows: Microsoft Windows is the most popular operating system for personal computers. There are several versions of the Windows operating system, including Windows XP (for home users) and Windows 2000 (for professional users). Earlier versions of Windows include Windows 3.1, 95, 98, ME, and NT. All Windows platforms use a graphical user interface (GUI), like the Mac OS, and also offer a command-line interface for typing text commands.
Wireless: In the computing world, the term "wireless" can be rather ambiguous, since it may refer to several different wireless technologies. The two most common types of wireless capabilities computers have are Wi-Fi and Bluetooth.
WLAN Wireless local area network. Instead of wires, stations on a WLAN connect to each other through radio waves. The IEEE 802.11, family of standards guides the development of WLANs.
Woofer A loudspeaker that reproduces bass frequency.
WPA: Wi-Fi Protected Access. A security protocol developed by the Wi-Fi Alliance to secure wireless networking takes the place of WEP; the most secure version is WPA2.
WSXGA: WSXGA defines a class of SXGA displays with a width resolution sufficient to create an aspect ratio of 16:9. Resolution is defines by the number of individual dots (pixels) that a display uses to create an image. A WSXGA display has 1920 to 1600 horizontal pixels and 1080 to 900 vertical pixels respectively that are used to compose the image delivered by the projector.
WXGA: WXGA defines a class of XGA displays with a width resolution sufficient to create an aspect ratio of 16:9. Resolution is defines by the number of individual dots (pixels) that a display uses to create an image. A WXGA display has 1366 to 1280 horizontal pixels and 768 to 720 vertical pixels respectively that are used to compose the image delivered by the projector.
