by Apple that combines analog and digital signals, USB, and power in a single
cable.
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 defi nes specifi c
electrical properties of the wire, but it is most commonly known as being rated
for its Ethernet capability of 100 Mbit/s. Its specifi c 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.
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 confi guring the display.
