Pixel
The smallest element of a display, a dot of color on your
display screen. The more pixels per area the clearer your
image will appear.
POST
Power On Self Test. A program which is part of the BIOS
which checks the configuration and operating condition
of your hardware whenever power is applied to your
LifeBook notebook. Status and error messages may be
displayed before the operating system is loaded. If the
self test detects failures that are so serious that operation
can not continue, the operating system will not be
loaded.
Program
An integrated set of coded commands to your
computers telling your hardware what to do and how
and when to do it.
PS/2
An IBM series of personal computers which established
a number of standards for connecting external devices
such as keyboards and monitors.
RAM
Random Access Memory. A hardware component of
your LifeBook notebook that holds binary information
(both program and data) as long as it has the proper
power applied to it.
RAM Module
A printed circuit card with memory and associated
circuitry which allows the user to add additional
memory to the computer without special tools.
Reset
The act of reloading the operating system. A reset erases
all information stored in RAM.
Restart
See Reset.
Resume
To proceed after interruption. In your LifeBook note-
book this refers to returning to active operation after
having been in one of the suspension states.
ROM
Read Only Memory. A form of memory in which infor-
mation is stored by physically altering the material. Data
stored in this way can not be changed by your LifeBook
notebook and does not require power to maintain it.
90
SDRAM
Synchronous Dynamic Random Access Memory.
Serial Port
A connection to another device through which data is
transferred one bit at a time on a single wire with any
other wires only for control of the device not for transfer
of data.
Shadow RAM
A technique of copying data or applications stored in
ROM (Read Only Memory) into RAM (Random Access
Memory) for access during actual operation. RAM is
much faster to access than ROM, however ROM
contents are not lost when power is removed.
Shadowing allows permanently stored information
to be rapidly accessed.
Smart Card
Smart Cards are the same size and shape as credit cards,
but they contain an integrated microprocessor chip. The
chip can hold a variety of different information, and
provides the user with many possible options, such as
allowing them to make secure purchases, pay for phone
calls, store security information, and provide personal
identification and information.
SRAM
Static Random Access Memory. A specific technology
of making RAM which does not require periodic
data refreshing.
Status Indicator
A display which reports the condition of some portion
of your hardware. On your LifeBook notebook this is an
LCD screen just above the keyboard.
Stereo (audio)
A system using two channels to process sound from two
different sources.
Stroke (keyboard)
The amount of travel of a key when it is pressed from
resting to fully depressed.
Suspend
To make inoperative for a period of time. Your LifeBook
notebook uses various suspension states to reduce power
consumption and prolong the charge of your battery.
SVGA
Super VGA.
