DeCSS is a software program that allows decryption of a CSS-encrypted movie and copying of the files to a hard disc (CSS stands for content scrambling system, and it’s used to protect the content of a DVD disc.) The DeCSS utility made online trading of DVD movies possible, although the interactive elements and outstanding audio/visual quality of DVD are compromised in the process.

A web page is interactive when it prompts a response from the user.
Immediacy is the key to interactivity: If you click on a button that says “chat,” then that experience would be considered “more interactive” if you are immediately able to chat with someone online. The experience would be “less interactive” if the response was an email address for a mailing list on which you are allowed to discuss a particular issue. Interactive is really just another code word for describing how graphical elements in web pages work together with the software behind them.
The red, green, and blue (RGB) color system can represent a large portion of the color spectrum by mixing these three primary colors. Since cathode ray tube devices, such as computer monitors, display color with red, green, and blue light, this is the color system of the Web. There are 216 RGB colors that appear without dithering (i.e., without varying the pattern of dots in an image) in browsers for the PC and Macintosh platforms. (see Hexadecimal, Palette, CMYK)
Extensible hypertext markup language is a hybrid between HTML 4.0 and XML. The main goal of XHTML is to provide a way for authors to update their HTML documents so that they are compliant with the XML standard, thus allowing them to be viewed with the next generation of XML browsers.
