Glossary
Boot
To start-up a computer and load its operating system
from disk, ROM or other storage media into RAM.
AC Adapter
A device which converts the AC voltage from a
wall outlet to the DC voltage needed to power
your LifeBook notebook.
Bus
An electrical circuit which passes data between the CPU
and the sub-assemblies inside your LifeBook notebook.
ACPI
Advanced Configuration and Power Interface
Byte
8 bits of parallel binary information.
Active-Matrix Display
A type of technology for making flat-panel displays
which has a transistor or similar device for every pixel
on the screen.
Cache Memory
A block of memory built into the micro-processor which
is much faster to access than your system RAM and used
in specially structured ways to make your overall data
handling time faster.
AdHoc
A name of a wireless LAN configuration.
It is a type of communication using wireless cards only.
Another type of communication is called Infrastructure
(using a wireless card and an access point).
ADSL
Asymmetric Digital Subscriber Line
Technology for transporting high bit-rate services over
ordinary phone lines.
AGP
Accelerated Graphics Port
CardBus
A faster, 32-bit version of the PC Card interface which
offers performance similar to the 32-bit PCI
architecture.
CD-ROM
Compact disk read only memory. This is a form of
digital data storage which is read optically with a laser
rather than a magnetic head. A typical CD-ROM can
contain about 600MB of data and is not subject to heads
crashing into the surface and destroying the data when
there is a failure nor to wear from reading.
Channel
Graphics port specifically designed for graphics-intensive devices, such as video cards and 3D accelerators.
A radio frequency band used for communication
between wireless cards and access points.
Auto/Airline Adapter
A device which converts the DC voltage from an automobile cigarette lighter or aircraft DC power outlet to
the DC voltage needed to power your LifeBook notebook.
CMOS RAM
Complementary metal oxide semiconductor random
access memory. This is a technology for manufacturing
random access memory which requires very low levels of
power to operate.
BIOS
Basic Input-Output System. A program and set of
default parameters stored in ROM which tests and
operates your LifeBook notebook when you turn it on
until it loads your installed operating system from disk.
Information from the BIOS is transferred to the installed
operating system to provide it with information on the
configuration and status of the hardware.
COM Port
Abbreviation for communication port. This is your
serial interface connection.
Bit
An abbreviation for binary digit. A single piece of
information which is either a one (1) or a zero (0).
Configuration
The combination of hardware and software that makes
up your system and how it is allocated for use.
bps
An abbreviation for bits per second. Used to describe
data transfer rates.
CRT
Cathode Ray Tube. A display device which uses a beam
of electronic particles striking a luminescent screen. It
Command
An instruction which you give your operating system.
Example: run a particular application or format a floppy
disk.
