Appendix
Twisted-Pair Cable
The cable used to connect the Ethernet card to a host (generally a Hub or Switch) is called a straight-
through Twisted Pair Ethernet (TPE). The end connectors are called RJ-45 connectors, which are not
compatible with RJ-11 telephone connectors. If connecting two computers together without a hub in
between, a crossover twisted-pair is required.
UltraDMA/66 or 100
UltraDMA/66 or 100 are new specifications to improve IDE transfer rates. Unlike traditional PIO
mode, which only uses the rising edge of IDE command signal to transfer data, UltraDMA/66 or 100
uses both rising edge and falling edge.
USB (Universal Serial Bus)
A new 4-pin serial peripheral bus that allows plug and play computer peripherals such as keyboard,
mouse, joystick, scanner, printer and modem/ISDN to be automatically configured when they are at-
tached physically without having to install drivers or reboot. With USB, the traditional complex cables
from back panel of your PC can be eliminated.
