 Accessibility

Accessibility is a term referring to the level of a web page’s ability to be viewed and used by everyone, specifically focusing on the needs of the disabled. Accessibility takes into consideration those with limited vision, loss of vision, color blindness, deafness, language impairments, alternative browsers, and restricted mobility.

Websites that meet accessibility standards are compatible with accessibility aids, such as speaking tools that enable blind users to access sites with the help of a speech reader or voice input utilities and on-screen keyboards that permit the user to choose from a list of available commands and objects. The WAI is responsible for formulating and publishing guidelines on web accessibility. See WAI, Assistive Technology.

ActiveX

AIFF

Aliasing

The process by which smooth curves and other lines become jagged because the resolution of the graphics device or file is not high enough to represent a smooth curve. See Anti-aliasing.

Analog

A transmission or process method using a series of continuous waves. A typical analog device is a clock in which the hands move continuously around the face and thus is capable of indicating every possible time of day. In contrast, a digital clock is capable of representing only a finite number of times (every tenth of a second, for example). Other examples of analog technology are phone transmissions and television broadcasts. See Modem.

Sometimes called "pure text" files, ASCII is a code for representing English characters as numbers, with each letter assigned a number from 0 to 127. For example, the ASCII code for M is 77. Most computers use ASCII codes to represent text, which makes it possible to transfer data from one computer to another. Compare with Unicode.

See ActiveX, VBScript, JavaScript, CGI, JSP.
