W3C

Example: "The W3C has developed several HTML, CSS, and XML standards for the Web."

W3C is short for "World Wide Web Consortium." The W3C is an international organization that develops Web standards. It is comprised of a full-time staff, a community of member organizations, and industry experts. By creating and publishing Web standards, the W3C aims to help ensure the long-term growth of the Web. Software developers and device manufacturers can adopt the W3C standards, which helps ensure their programs and equipment will work with the latest Web technologies.

WAIS

Stands for "Wide Area Information Server." This is a program that can index enormous amounts of information and make it searchable across large networks (including the Internet). People can search the WAIS index and it will return results by relevance. Searches can then be narrowed down by subsequent searches on the original results. Search engines are a new and improved version of WAIS, specifically for the Web.

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. You could even call the Internet a Super WAN BAM if you wanted to. Or maybe not.

Waveform

A waveform is an image that represents an audio signal or recording. It shows the changes in amplitude over a certain amount of time. The amplitude of the signal is measured on the y-axis (vertically), while time is measured on the x-axis (horizontally).

Most audio recording programs show waveforms to give the user a visual idea of what has been recorded. If the waveform is very low and not pronounced, the recording was probably very soft. It the waveform almost fills the entire image, the recording may have been too "hot" or recorded with the levels set too high. Changes in a waveform are also good indicators as too when certain parts of a recording take place. For example, the waveform may be small when there is just a vocalist singing, but may become much larger when the drums and guitar come in. This visual representation enables audio producers to locate certain parts of a song without even listening to the recording.

Web 2.0

Web 2.0 is term that was introduced in 2004 and refers to the second generation of the World Wide Web. The term "2.0" comes from the software industry, where new versions of software programs are labeled with an incremental version number. Like software, the new generation of the Web includes new features and functionality that was not available in the past. However, Web 2.0 does not refer to a specific version of the Web, but rather a series of technological improvements.

Some examples of features considered to be part of Web 2.0 are listed below:

Blogs - also known as Web logs, these allow users to post thoughts and updates about their life on the Web.

Wikis - sites like Wikipedia and others enable users from around the world to add and update online content.

Social networking - sites like Facebook and MySpace allow users to build and customize their own profile sand communicate with friends.

Web applications - a broad range of new applications make it possible for users to run programs directly in a Web browser.

Web 2.0 technologies provide a level user interaction that was not available before. Websites have become much more dynamic and interconnected, producing "online communities" and making it even easier to share information on the Web. Because most Web 2.0 features are offered as free services, sites like Wikipedia and Facebook have grown at amazingly fast rates. As the sites continue to grow, more features are added, building off the technologies in place. So, while Web 2.0 may be a static label given to the new era of the Web, the actual technology continues to evolve and change.

Web Browser

You are probably using a browser to read this right now. 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, Netscape Communicator, and Apple Safari.

Web Host

In order to publish a website online, you need a Web host. The Web host stores all the pages of your website and makes them available to computers connected to the Internet. The domain name, such as "sony.com," is actually linked to an IP address that points to a specific computer. When somebody enters your domain name into their browser's address field, the IP address is located and Web site is loaded from your Web host.

A Web host can have anywhere from one to several thousand computers that run Web hosting software, such as Apache, OS X Server, or Windows Server. Most websites you see on the Web are accessed from a "shared host," which is a single computer that can host several hundred Web sites. Larger websites often use a "dedicated host," which is a single machine that hosts only one website. Sites with extremely high amounts of traffic, such as apple.com or microsoft.com, use several computers to host one site.

If you want to publish your own website, you'll need to sign up for a "Web hosting service." Finding a good Web host shouldn't be too hard, since their are thousands available. Just make sure the Web host you choose offers good technical support and ensures little or no downtime. You'll usually have to pay a monthly fee that varies depending on how much disk space and bandwidth your site will use. So it's a good idea to estimate how big your site will be and how much traffic you expect before signing up for a Web hosting service.

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.

Please 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.

Web Ring

A Web ring is a way of interlinking related Web sites so that people can visit many similar Web sites by just following the "Web ring" link on each page. Most Web rings allow people to browse backwards or forwards through the sites in the ring, or choose to visit individual sites from a list. The rings are typically run from a main site which uses a Web scripting application to select random sites and keep the ring up to date. This includes getting rid of outdated pages and links, and adding new ones. There are tens of thousands of Web rings for topics like football, cars, celebrities, computers, TV shows, etc. You can tell if a Web page is part of Web ring if on the bottom of the page it has some huge, obtrusive, off-color, button linking to other sites in the ring.

Webcam

The term webcam is a combination of "Web" and "video camera." The purpose of a webcam is, not surprisingly, to broadcast video on the Web. 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.

Webcams 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.

Since streaming video over the Internet requires a lot of bandwidth, the video stream is typically compressed to reduce the "choppiness" of the video. The maximum resolution of a webcam is also lower than most handheld video cameras, since higher resolutions would be reduced anyway. For this reason, webcams are relatively inexpensive compared to most video cameras. And while they may not be ideal for filming a movie, webcams are great for video chat sessions with friends.

Webmail

There are two primary ways of checking your e-mail – using an e-mail program like Microsoft Outlook or with a Web-based interface called webmail. When you check or send e-mail via the Web, you are using webmail. Most free e-mail services, such as Gmail, Hotmail, and Yahoo! Mail offer webmail interfaces that allow you to send, receive, and organize your e-mail on the Web. If you own a domain name, many Web hosts also offer a webmail interface to use with your domain name or website. Some common webmail systems supported by Web hosts include Horde, NeoMail, and SquirrelMail.

Because webmail is run from a server, the messages downloaded to your inbox are saved on the mail server. This is convenient since you can check your mail and browse old messages from any computer as long as you have an Internet connection. The downside is that, since the messages are not downloaded to your computer, you need an Internet connection to view your messages – even ones that you have already viewed.

If you only have one e-mail account, webmail may be the simplest way to check, send, and manage your e-mail. However, if you regularly use multiple e-mail accounts, a software e-mail client like Microsoft Outlook or Mac OS X Mail may be a better choice.

Webmaster

The webmaster is the person in charge of maintaining a Web site. The jobs of a webmaster include writing HTML for Web pages, organizing the Web site's structure, responding to e-mails about the Web site, and keeping the site up-to-date. On some Web sites you might see a phrase that says, "send dead links and other Web site problems to webmaster@domainame.com." At times, being a webmaster can be a rather arduous job. I received some dead links in the mail one time, and let me tell you, it wasn't pretty.

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. For example, Amazon.com is a Web site, but there are millions of Web pages that make up the site. Knowing the difference between these two terms can save you a lot of embarrassment.

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.

The wired equivalent privacy protocol adds security to a wireless network by encrypting the data. If the data is intercepted, it will be unrecognizable to system that intercepted the data, since it is encrypted. However, authorized systems on the network will be able to recognize the data because they all use the same encryption algorithm. Systems on a WEP-secured network can typically be authorized by entering a network password.

White Balance

Example: "He set his camera's white balance to tungsten lighting while he took pictures indoors."

White balance is a setting available on most digital cameras and camcorders that defines how the color white should appear in the current lighting conditions. A correct white balance setting prevents images from having a certain hue cast over the image, such as the greenish color caused by fluorescent lights. Most devices include an auto white balance (AWB) feature, which automatically adjusts the white balance when taking pictures and recording video. Some digital cameras and camcorders also include selectable white balance presets for different types of lighting.

If you've already imported a bunch of pictures that have a strange hue over them, it is most likely because the white balance was not set properly. Fortunately, most modern image editing applications include color adjustment tools that can remove these hues.
