In hardware virtualization, the term host machine refers to the actual machine on which the virtualization takes place; the term guest machine, however, refers to the virtual machine. Likewise, the adjectives host and guest are used to help distinguish the software that runs on the actual machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or Virtual Machine Monitor.

A technique that enables a certain portion of hard disk space to be used as auxiliary memory so that your computer can access larger amounts of data than its main memory can hold at one time.
An artificial environment created with computer hardware and software to simulate the look and feel of a real environment. A user wears earphones, a special pair of gloves, and goggles that create a 3D display. Examples: manipulating imaginary 3D objects by “grabbing” them, taking a tour of a “virtual” building, or playing an interactive game.
A program intended to alter data on a computer in an invisible fashion, usually for mischievous or destructive purposes. Viruses are often transferred across the Internet as well as by infected diskettes and can affect almost every type of computer. Special antivirus programs are used to detect and eliminate them.
Voice over Internet Protocol; a means of using the Internet as the transmission medium for phone calls. An advantage is you do not incur any additional surcharges beyond the cost of your Internet access.
Virtual Private Networking; a means of securely accessing resources on a network by connecting to a remote access server through the Internet or other network.
A type of terminal emulation required when you open an interactive network connection (telnet) to a UNIX system from your desktop computer.
Wide Area Information Server; a program for finding documents on the Internet. Usually found on gopher servers to enable searching text-based documents for a particular keyword.
Wide Area Network; a group of networked computers covering a large geographical area (e.g., the Internet).
Wireless Application Protocol; a set of communication protocols for enabling wireless access to the Internet.
Wired Equivalent Privacy; a security protocol for wireless local area networks defined in the 802.11b standard. WEP provides the same level of security as that of a wired LAN.
Wireless Fidelity; A generic term from the Wi-Fi Alliance that refers to of any type of 802.11 network (e.g., 802.11b, 802.11a, dual-band, etc.). Products approved as “Wi-Fi Certified” (a registered trademark) are certified as interoperable with each other for wireless communications.
A special character provided by an operating system or a particular program that is used to identify a group of files or directories with a similar characteristic. Useful if you want to perform the same operation simultaneously on more than one file. Example: the asterisk (*) that can be used in DOS to specify a groups of files such as *.txt.
On a graphical user interface system, a rectangular area on a display screen. Windows are particularly useful on multitasking systems which allow you to perform a number of different tasks simultaneously. Each task has its own window which you can click on to make it the current process. Contrast to a “dialog box” which is used to respond to prompts for input from an application.
A casual way of referring to the Microsoft Windows operating systems.
The ability to access the Internet without a physical network connection. Devices such as cell phones and PDAs that allow you to send and receive e-mail use a wireless Internet connection based on a protocol called WAP (Wireless Application Protocol). At this point, web sites that contain wireless Internet content are limited, but will multiply as the use of devices relying on WAP increases.
A special utility within some applications that is designed to help you perform a particular task. Example: the wizard in Microsoft Word that can guide you through creating a new document.
Wireless Local Area Network; the computers and devices that make up a wireless network.
A graphical user interface (GUI) computer with computing power somewhere between a personal computer and a minicomputer (although sometimes the distinction is rather fuzzy). Workstations are useful for development and for applications that require a moderate amount of computing power and relatively high quality graphics capabilities.
World Wide Web:
A hypertext-based system of servers on the Internet. Hypertext is data that contains one or more links to other data; a link can point to many different types of resources including text, graphics, sound, animated files, a network newsgroup, a telnet session, an FTP session, or another web server. You use a special program called a “browser” (e.g., Firefox or Internet Explorer) for viewing World Wide Web pages. Also referred to as “WWW” or “the web”.
A program that makes copies of itself and can spread outside your operating system worms can damage computer data and security in much the same way as viruses.
Wi-Fi Protected Access; a standard designed to improve on the security features of WEP.
An abbreviation for World Wide Web.
What You See Is What You Get; a kind of word processor that does formatting so that printed output looks identical to what appears on your screen.
A technology that enables data transmission speeds up to 56 Kbps using regular telephone service that is connected to switching stations by high-speed digital lines. This technology affects only transmissions coming into your computer, not to data you send out. In addition, your ISP must have a modem at the other end that supports X2.
Extensible Hypertext Markup Language. A spinoff of the hypertext markup language (HTML) used for creating Web pages. It is based on the HTML 4.0 syntax, but has been modified to follow the guidelines of XML and is sometimes referred to as HTML 5.0.
Extensible Markup Language; A markup language for coding web documents that allows designers to create their own customized tags for structuring a page.
zero-day (or zero-hour or day zero) attack, threat or virus is a computer threat that tries to exploit computer application vulnerabilities that are unknown to others or the software developer, also called zero-day vulnerabilities. Zero-day exploits (actual software that uses a security hole to carry out an attack) are used or shared by attackers before the developer of the target software knows about the vulnerability.
A common file compression format for PC or compatibles; the utility WinZip or Winrar is used for compressing and decompressing files. Zipped files usually end with a “.zip” file extension. A special kind of zipped file is self-extracting and ends with a “.exe” extension. Macintosh OSX also supports the .zip format and has tools that can compress and decompress zip files.
A high capacity floppy disk drive from Iomega Corporation; the disks it uses are a little bit larger than a conventional diskette and are capable of holding 100 MB or 250 MB of data.
The act of enlarging a portion of an onscreen image for fine detail work; most graphics programs have this capability.
