RAM (Random Access Memory)
RAM (usually just called memory) is the place in a computer where the operating system, applica-
tion programs, and data in current use are temporarily kept so that they can be quickly reached by
the computer’s processor instead of having to read from and write to slower storage such as the
hard disk or optical disc.
Standby Mode
A power mode that enables a computer to save power consumption while not in use. When a
computer is in Standby Mode, the data on the computer memory is not saved onto the hard disk.
If the power is tuned off, the data in memory will be lost.
Suspend Mode
In Save-to-RAM (STR) and Save-to-Disk (STD), the CPU clock is stopped and most of the
UltraMobilePC devices are put in their lowest active state. The UltraMobilePC enters Suspend
when the system remains idle for a specified amount of time or manually using the function keys.
The time-out setting of both Hard Disk and Video can be set by the BIOS Setup. The Power LED
blinks when the UltraMobilePC is in STR mode. In STD mode, the UltraMobilePC 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 operat
-
ing system.
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/ 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
attached physically without having to install drivers or reboot. With USB, the traditional complex
cables from back panel of your computer can be eliminated.
Windows
The name of the operating system developed by Microsoft Corporation and used on this com-
puter.
