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
Self-Monitoring, Analysis and Reporting Technology
(SMART) is an emerging technology that provides near-
term failure predictions for hard drives. When SMART is
enabled the hard drive monitors pre-determined drive
attributes that are susceptible to degradation over time.
If a failure is likely to occur, SMART makes a status
report available so that the LifeBook can prompt the
user to back up the data on the drive. Naturally not all
failures are predictable. SMART predictability is limited
to those attributes which the drive can self-monitor. In
those cases where SMART can give advance warning, a
considerable amount of precious data can be saved.
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
To make inoperative for a period of time. Your LifeBook
uses various suspension states to reduce power
consumption and prolong the charge of your battery.
SVGA
Super VGA.
S-Video
Super Video. A component video system for driving a
TV or computer monitor.
86
System Clock
An oscillator of fixed precise frequency which synchro-
nizes the operation of the system and is counted to
provide time of day and date.
TFT
Thin Film Transistor – A technology for flat display
panels which uses a thin film matrix of transistors to
control each pixel of the display screen individually.
UL
Underwriters Laboratories – An independent organiza-
tion that tests and certifies the electrical safety of devices.
VGA
Video Graphics Array. A video display standard
originally introduced by IBM with the PS/2 series of
personal computers.
VRAM
Video Random Access Memory. A memory dedicated to
video display data and control.
WFM
Wired for Management is Intel's broad-based initiative
to reduce the total cost of ownership (TCO) of business
computing without sacrificing power and flexibility.
Write Protect
Prevent alteration of the binary state of all bits in a
storage media. Example: all information on a device
such as a floppy diskette; a block of space in a storage
media such as a partition of a hard drive; a file or direc-
tory of floppy diskette or hard drive.
XGA
Extended VGA.
Zip Drive
A 100MB read/write removable media disk drive.
Zoomed Video
A PC Card port which allows LifeBook PCs to deliver
full screen broadcast quality video through third party
PC Cards, including TV tuners, video capture, and
MPEG full-motion video.
