Biography:
On a computer that is provided with a desktop kind of user interface, wallpaper is the background pattern or picture against which desktop menus, icons, and other elements are displayed and moved around. A wallpaper image can be in a JPEG or a GIF file format. Wallpaper is commonly used in Microsoft Windows, Macintosh Mac OS, Linux, and in other operating systems as well. Each operating system provides several pre-installed wallpaper images for the user to choose from. A user can also choose to download and install third-party wallpapers and use one of these instead.
Typically, a wallpaper image may be centered, stretched, or tiled. When an image is centered, it is placed in the middle of the desktop and is surrounded by a solid color. When an image is stretched, it is stretched to cover all of the desktop. Only certain images can be stretched or they look distorted. An image that is tiled is placed on the desktop much like tiles are placed in a shower or a tiled floor. Tiling is commonly used for patterns instead of photos because a pattern is one square image that repeats itself across and down the screen, effectively forming a single image.
A desktop theme is a customized graphical user interface (GUI) that replaces a computer's ordinary sounds, icons, pointer, wallpaper or screensaver with something designed to reflect the interests of the user. For instance, if you were interested in bass fishing, you could have a picture of a lake for your computer wallpaper, icons that resemble different kinds of fishing lures, sounds that are related to boats, water and fishing reels, a screen saver from your favorite TV show about bass fishing, and a pointer that looks like a fish. Although desktop themes are popular for home use, many network administrators frown upon desktop themes, primarily because it is possible for a user to inadvertently introduce a virus by downloading a theme from an unknown source.
There are free desktop themes, as well as shareware themes, available on the Internet for all operating systems. It is also possible for users to create their own desktop themes. Microsoft used to require that users purchase an application called Microsoft Plus! to use desktop themes, but they included it as standard issue in Windows 98 and Windows Me. The initial release of Windows 2000 does not include the Plus! package (or its equivalent), although high customer demand leads some industry watchers to predict that the Plus! package will either be included in the next edition of Windows 2000, or be released separately (as it was for Windows 95). In Linux, the latest version of the KDE graphical desktop environment includes a tool to enable users to change their desktop theme. In the spirit of "if you can't beat them, join them", IBM is sponsoring a desktop theme contest for Linux users; first prize is a three thousand dollar donation to the winner's favorite non-profit Open Source organization.
