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. 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 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 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 and does not require power to maintain it.
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
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 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

SVGA
Super VGA.
Super Video. A component video system for driving a TV or computer monitor.
