A Appendix

RAM (Random Access Memory)

There are several different types of RAM such as DDR (Double Dynamic RAM), DRAM (Dynamic

RAM), EDO DRAM (Extended Data Output DRAM), SDRAM (Synchronous DRAM).

ROM (Read Only Memory)

ROM is nonvolatile memory used to store permanent programs (called firmware) used in certain com-

puter components. Flash ROM (or EEPROM) can be reprogrammed with new programs (or BIOS).

Suspend Mode

In Save-to-RAM (STR) and Save-to-Disk (STD), the CPU clock is stopped and most of the Notebook

PC devices are put in their lowest active state. The Notebook PC enters Suspend when the system

remains idle for a specified amount of time or manually using the function keys. The timeout setting of

both Hard Disk and Video can be set by the BIOS Setup. The Power LED blinks when the Notebook PC

is in STR mode. In STD mode, the Notebook PC will appear to be powered OFF.

System Disk

A system disk contains the core file of an operating system and is used to boot up the operating system.

TPM (Trusted Platform Module)

The TPM is a security hardware device on the system board that will hold computer-generated keys for

encryption. It is a hardware-based solution that can help avoid attacks by hackers looking to capture

passwords and encryption keys to sensitive data. The TPM provides the ability to the PC or notebook to

run applications more secure and to make transactions and communication more trustworthy.

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.
