MP3 (MPEG-1 Audio Layer-3) is an audio compression format that creates files that can be easily sent or downloaded across the internet.
Using ripper and encoder applications, CD tracks can be converted to MP3 and reduced in size by a factor of 12. MP3 files have varying degrees of sound quality, depending on the encoding settings that are used during the compression process.
The hexadecimal (base 16) number system used for Web-page design consists of 16 unique symbols:0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
For example, the decimal number 15 is equal to the hexadecimal number F. In HTML, an RGB
color can be designated by
with the first two numerals representing the amount of red, the second two the amount of green, and the last two the amount of blue. If you wanted your background to be red, you could write the code for a body background color as
Black is the absence of all color and white is the presence of all color, so in hexadecimal, black is at the bottom of the system (no red, green, or blue:
and white is at the top (the maximum amount of red, green, and blue:
The Pantone Matching System (PMS) is a popular system for printing inks. Often a printer has two choices for creating an ink color:process color and spot color. Process color uses a mixture of four specific colors – cyan, magenta, yellow, and black – to create the desired shade. Spot color uses a matching system to create the shade. By specifying the official Pantone name or number, you can be assured of the color match when the file is printed.
A router (not to be confused with a bridge) is a data network device that transfers data from one LAN to another. Routers can be hardware- or software-based, though larger applications and faster communication speeds all but require a hardware router. Routers are used in homes and offices with high-speed internet access such as DSL; they serve to connect the local LAN to the high-speed WAN operated by a service provider.
Tabular Data Control is a Microsoft ActiveX control that will sort through a data file, extrapolate the necessary information, and produce that information in specified areas on the web page. This will create output either all at once, in tabular form, or according to user-defined settings (through a scripting language). As a web production tool, the tabular data control can minimize production by allowing a page to be built once and then pouring subsequent information into it as desired. Once the web page is built using the tabular data control, you only have to worry about putting the information in a format the control can easily read.
