Web Design Glossary
The World Wide Web has become a major delivery platform for a variety of complex and sophisticated enterprise applications in several domains. In addition to their inherent multifaceted functionality, these Web applications exhibit complex behavior and place some unique demands on their usability, performance, security and ability to grow and evolve.
AJAX - AJAX stands for or Asynchronous Javascript and XML. It's a way to utilize the abilities of Javascript, the Document Object Model, and XML to create interactivity on the web. For more information visit: AJAX (Asynchronous JAvaScript + XML or Asynchronous JAvascript using XMLHttpRequest)
Aliasing - In graphic design, aliasing occurs when a computer monitor, printer, or graphics file does not have a high enough resolution to represent a graphic image or text. An aliased image is often said to have the "jaggies."
Alignment - The positioning of a body of text. Text can be positioned to the left, right, or "center" of a page. For the best, consistent alignment, web site designers use tables and Cascading Style Sheets.
ALT-attribute - Part of the image source tag in HTML. A good web designer will always include text in all of your image sources for two reasons: (1) if any of your visitors choose not to view graphic images on your web pages, the alternative text will be shown; and (2) if your visitors use Internet Explorer as their browser and they leave the mouse over any graphic image, they will view the text in your ALT-attribute.
Animation - Animation is the creating a timed sequence or series of graphic images or frames together to give the appearance of continuous movement. Animation is the rapid display of a sequence of images of 2-D or 3-D artwork or model positions in order to create an illusion of movement. It is an optical illusion of motion due to the phenomenon of persistence of vision, and can be created and demonstrated in a number of ways. The most common method of presenting animation is as a motion picture or video program, although several other forms of presenting animation also exist.
Anti-Aliasing - Smoothing or blending the transition of pixels in an image. Anti-aliasing the edges on a graphic image makes the edges appear smooth, not jagged.
in digital signal processing, anti-aliasing is the technique of minimizing the distortion artifacts known as aliasing when representing a high-resolution signal at a lower resolution. Anti-aliasing is used in digital photography, computer graphics, digital audio, and many other applications.
Anti-aliasing means removing signal components that have a higher frequency than is able to be properly resolved by the recording (or sampling) device. This removal is done before (re-)sampling at a lower resolution.
Banner - A banner is a graphic image (static, animated, or rich media) that is placed on web sites as an advertisement. Banners are commonly used for brand awareness and generating sales.it is the difference between the upper and lower cutoff frequencies of, for example, a filter, a communication channel, or a signal spectrum, and is typically measured in hertz. In case of a baseband channel or signal, the bandwidth is equal to its upper cutoff frequency. Bandwidth in hertz is a central concept in many fields, including electronics, information theory, radio communications, signal processing, and spectroscopy.
Bitmap Image - A graphic image stored as a specific arrangement of screen dots, or pixels. Web graphics are bitmap images. A graphic which is defined by specifying the colors of dots or pixels which make up the picture. Also known as raster graphics. Common types of bitmap graphics are GIF, JPEG, Photoshop, PCX, TIFF, Macintosh Paint, Microsoft Paint, PNG, FAX formats, and TGA.
