Glossary
AC Adapter
A device which converts the AC voltage from a
wall outlet to the DC voltage needed to power
your LifeBook notebook.
ACPI
Advanced Configuration and Power Interface
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.
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.
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.
Bit
An abbreviation for binary digit. A single piece of
information which is either a one (1) or a zero
(0).
bps
An abbreviation for bits per second. Used to
describe data transfer rates.
Boot
To start-up a computer and load its operating
system from disk, ROM or other storage media
into RAM.
Bus
An electrical circuit which passes data between
the CPU and the sub-assemblies inside your
LifeBook notebook.
Byte
8 bits of parallel binary information.
Cache Memory
A block of memory built into the microprocessor
which is much faster to access than your system
RAM and used in specially structured ways to
make your overall data handling time faster.
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
A radio frequency band used for communication
between wireless cards and access points.
CMOS RAM Complementar y metal oxide
semiconductor random access memory. This is
a technology for manufacturing random access
memory which requires very low levels of power
to operate.
COM Port
Abbreviation for communication port. This is your
serial interface connection.
