• FTP. File Transfer Protocol. A way of transferring files from one computer to another over the Internet without altering their basic structure.

• HTTP. Hyper Text Transfer Protocol. A way of transferring files form one computer to another over the Internet and displaying them through a graphical browser (e.g., Netscape or Microsoft Internet Explorer).

• A HREF. HTML code term technically meaning "argument hypertext reference" but more or less meaning "a link."

• ISO-9660. A file naming convention that can be read by DOS, Windows, UNIX, and MAC. Filenames are restricted to alphanumeric characters and underscores, with up to eight characters, a period, and another three characters (e.g., file_1.htm)

• RGB. A way of naming colors by their Red, Green, and Blue values. Image manipulation programs, such as Photoshop, name them by assigning a value from 0 (none) to 255 (all) for red, blue, and green. These are "additive" colors -- mixing them together creates white. Four color printing, on the other hand, uses CYMK (Cyan, Yellow, Magenta, Black) color, which is "subtractive" -- adding them together creates black. Screen colors, and thus Web colors, are additive, so we use RGB values.

• URL. This is short for Uniform Resource Locator. It tells the browser what file to request, and what protocol to use for transfer and display.
