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.

Wi-Fi is the technology used for wireless networking. If your computer has a wireless card, it is most likely Wi-Fi compatible. The wireless card transmits to a wireless router, which is also based on the Wi-Fi standard. Wireless routers are often connected to a network, cable modem, or DSL modem, which provides Internet access to anyone connected to the wireless network.

Bluetooth is the technology often used for wireless keyboards and mice, wireless printing, and wireless cell phone headsets. In order to use a device such as a Bluetooth keyboard or mouse, your computer must be Bluetooth-enabled or have a Bluetooth adapter installed.

Computers may also use other wireless technologies aside from Wi-Fi and Bluetooth. Products such as remote controls and wireless mice may use infrared or other proprietary wireless technologies. Because of the many wireless options available, it is a good idea to check the system requirements of any wireless device you are considering buying.

Wizard

When most people think of a wizard, they think of an old man with magical powers. This, as with many other computer definitions, has no correlation with the technical term. In computer terminology, a wizard is a part of a program that guides you through certain steps. For example, a wizard in Microsoft Word would help you create and format a new document according to your needs. This is helpful when creating a r?sum?, outline, invoice, etc. Some other examples of wizards are the Finale 2000 wizard, which helps you create a new music composition with your desired instruments, and the PowerPoint wizard, which helps you set up a presentation using a certain theme.

Basically, a wizard acts as a guide for creating a new document in a software program. Though wizards can be helpful, sometimes they can be more of a hassle than a help for experienced users. Some users would rather just create a new document from scratch, without using a wizard. This is because wizards typically don't offer as much customization as an experienced user may want. Finally, be sure not to confuse a "wizard" with a "template." A template is a pre-formatted document that has already been created, whereas a wizard is a step-by-step guide that helps you create your own document.

Word Processor

A word processor, or word processing program, does exactly what the name implies. It processes words. It also processes paragraphs, pages, and entire papers. Some examples of word processing programs include Microsoft Word, WordPerfect (Windows only), AppleWorks (Mac only), and OpenOffice.org.

The first word processors were basically computerized typewriters, which did little more than place characters on a screen, which could then be printed by a printer. Modern word processing programs, however, include features to customize the style of the text, change the page formatting, and may be able to add headers, footers, and page numbers to each page. Some may also include a "Word Count" option, which counts the words and characters within a document.

While all these features can be useful and fun to play with, the most significant improvement over the typewriter is the word processor's ability to make changes to a document after it has been written. By using the mouse, you can click anywhere within the text of a document and add or remove content. Since reprinting a paper is much easier than retyping it, word processing programs have make revising text documents a much more efficient process.

The term "text editor" can also be used to refer to a word processing program. However, it is more commonly used to describe basic word processing programs with limited features.

Word Wrap

Word wrapping is when a line of text automatically "wraps" to the next line when it gets to the end of a page or text field. This is different than a "word rap," which involves rhyming words to a rhythmic beat, though that may be more fun than typing. Most word processing programs use word wrap to keep the text within the default margins of the page. Without the word wrap feature, text would continue on one line until the user pressed "Enter" or "Return" to insert a line break.

Most programs that incorporate word wrap take the first word that does not fit on a line of text and move it to the beginning of the next line. Advanced word processing programs can hyphenate long words at appropriate places. While it is uncommon, sometimes a word, or string of characters ,will take up more than one line. In this case, the word wrap feature will simply continue the string of characters onto the next line.

WordArt

WordArt is a text modifying feature in Microsoft Word, a popular word processing program. It includes effects such as shadows, outlines, colors, gradients, and 3D effects that can be added to a word or phrase. WordArt can also bend, stretch, skew, or otherwise modify the shape of the text.

WordArt can be added within a Word document by selecting Insert→Picture→WordArt... This opens the WordArt dialog box, which gives the user several text styles to choose from. Once a style has been selected, the user types the text that the style will be applied to and the result is saved as an image within the document. The WordArt can then be moved or modified by selecting Modify→WordArt.

The OpenOffice.org office suite has a similar feature to WordArt, called FontWork. Photoshop 7 and later also includes a Warp Text feature, which provides similar text modification options.

Workstation

It has been said that a bus stops at a bus station and a train stops at a train station, so what happens at a workstation? Hm...

Actually, a workstation is a place where work gets done. It refers to a computer (and often the surrounding area) that has been configured to perform a certain set of tasks, such as photo editing, audio recording, or video production. An office may have several workstations for different purposes, which may be assigned to certain employees. For example, one workstation may be used for scanning and importing images, while another is used for editing images.

Because workstations often work together like in the example above, they are commonly networked together. This allows them to send files back and forth over the network, which is important for various types of media production. To use another example, a user at a photo-editing workstation may prepare images to be used in a video clip. Once the images are ready, he may send them to another user at a video-editing workstation, where they are incorporated into the video. Once the video has been put together, the video file may be sent to another user at an audio production workstation where the soundtrack and other sound effects are added.

While workstations are often part of a network, they can be standalone machines as well. Even a home computer can be a workstation if it is used for certain kinds of work. So if you want to sound professional, the next time you send an e-mail to a friend from your home PC, you can let him know you are sending it from your home workstation.

Worm

Worm has two widely different definitions. One refers to a computer virus and the other is an optical storage technology:

1) A type of computer virus

Just like regular worms tunnel through dirt and soil, computer worms tunnel through your computer's memory and hard drive. A computer worm is a type of virus that replicates itself, but does not alter any files on your machine. However, worms can still cause havoc by multiplying so many times that they take up all your computer's available memory or hard disk space. If a worm consumes your memory, your computer will run very slowly and possibly even crash. If the worm affects your hard disk space, your computer will take a long time to access files and you will not be able to save or create new files until the worm has been eradicated.

Worms are hard to detect because they are typically invisible files. They often go unnoticed until your computer begins to slow down or starts having other problems. Unlike viruses and Trojan horses, worms can replicate themselves and travel between systems without any action from the user. For these reasons, it is good to have an antivirus program installed on your system that can detect and remove worms before they have a chance to replicate or spread to other computers. Security updates such as Windows Update also patch security holes that allow worms to infect your computer. So keep your security updates and virus definitions up-to-date and you should be able to keep your computer worm-free.

2) An optical storage technology

WORM can also mean "Write Once, Read Many." It is an optical storage technology that allows a disc to be written only once but read an unlimited number of times. WORM devices were introduced in the 1970's and gained popularity as a way of archiving data. The storage capacity of WORM discs began around 140MB, but increased to more than 3.0GB over the past few decades. Yet the WORM technology has no standard format, so WORM discs are only compatible with the drives that wrote them. This limitation has kept WORM equipment relatively expensive and has kept the technology from gaining widespread acceptance.

Today, most optical drives are based on either CD-R or DVD-R technology. Unlike WORM discs, CD-Rs and DVD-Rs can typically be read by any CD or DVD drive, regardless of the manufacturer. Because of their improved compatibility and lower costs, writable CDs and DVDs have all but replaced WORM media.

WPA

Stands for "Wi-Fi Protected Access." WPA is a security protocol designed to create secure wireless (Wi-Fi) networks. It is similar to the WEP protocol, but offers improvements in the way it handles security keys and the way users are authorized.

For an encrypted data transfer to work, both systems on the beginning and end of a data transfer must use the same encryption/decryption key. While WEP provides each authorized system with the same key, WPA uses the temporal key integrity protocol (TKIP), which dynamically changes the key that the systems use. This prevents intruders from creating their own encryption key to match the one used by the secure network.

WPA also implements something called the Extensible Authentication Protocol (EAP) for authorizing users. Instead of authorizing computers based soley on their MAC address, WPA can use several other methods to verify each computer's identity. This makes it more difficult for unauthorized systems to gain access to the wireless network.

WWW

Stands for "World Wide Web." It is important to know that this is not a synonym for the Internet. The World Wide Web, or just "the Web," as ordinary people call it, is a subset of the Internet. The Web consists of pages that can be accessed using a Web browser. The Internet is the actual network of networks where all the information resides. Things like Telnet, FTP, Internet gaming, Internet Relay Chat (IRC), and e-mail are all part of the Internet, but are not part of the World Wide Web. The Hyper-Text Transfer Protocol (HTTP) is the method used to transfer Web pages to your computer. With hypertext, a word or phrase can contain a link to another Web site. All Web pages are written in the hyper-text markup language (HTML), which works in conjunction with HTTP.

WYSIWYG

Stands for "What You See Is What You Get," and is pronounced "wihzeewig." WYSIWYG refers to software that accurately represents the final output during the development phase. For example, a desktop publishing program such as Photoshop is a WYSIWYG graphics program because it can display images on the screen the same way they will look when printed on paper. Word processing programs like Microsoft Word and Apple Pages are both WYSIWYG editors, because they include page layout modes that accurately display what the documents will look when printed.

While WYSIWYG originally referred to programs that produce physical output, the term is now also used to describe applications that produce software output. For example, most Web development programs are called WYSIWYG editors since they show what Web pages will look like as the developer is creating them. This means that the developer can move text and images around the page to make it appear exactly how he or she wants before publishing the page on the Web. When the page is published, it should appear nearly the same on the Web as the way it looked in the Web development program. Of course, as most Web developers know, there is no guarantee that a Web page will look the same in two different browsers, such as Internet Explorer and Firefox. But at least a WYSIWYG editor can give developers a close approximation of what the published page will look like.
