Glossary
- Method of sending and receiving data
- Process used to handle communication errors
Conditions required for communication are organized
in procedures for correct transfer of information.
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 notebook 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 notebook
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.
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 notebook can
prompt the user to back up the data on the drive. Natu-
rally not all failures are predictable. SMART predict-
ability 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.
SSID
Service Set Identifier
Specifies which network you are joining. Some systems
allow you to specify any SSID as an option so you can
join any network.
Standby
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.
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.
SVGA
Super VGA.
S-Video
Super Video. A component video system for driving a
TV or computer monitor.
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.
TCP/IP
Transmission Control Protocol/Internet Protocol.
A standard Internet protocol that is most widely used.
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.
