GLOSSARY

A

ADC

Apple Display Connector. The ADC interface is a proprietary interface developed by Apple that combines analog and digital signals, USB, and power in a single cable.

C

CAT-5

Category-5 cable, commonly known as Cat-5, is an unshielded twisted pair type cable designed for high signal integrity. The actual standard defines specific electrical properties of the wire, but it is most commonly known as being rated for its Ethernet capability of 100 Mbit/s. Its specific standard designation is EIA/ TIA-568. Cat 5 cable typically has three twists per inch of each twisted pair of 24 gauge copper wires within the cable.

CAT-5e

Similar to Cat 5 cable, but is enhanced to support speeds of up to 1000 megabits per second.

CRT

An acronym for Cathode Ray Tube: a common type of computer display hardware.

D

DDC

Short form for Display Data Channel. It is a VESA standard for communication between a monitor and a video adapter. Using DDC, a monitor can inform the video card about its properties, such as maximum resolution and color depth.

The video card can then use this information to ensure that the user is presented with valid options for configuring the display.
