PPPoE
Point to Point Protocol over Ethernet.
A protocol for Ethernet, using a Point-to-Point Protocol
(PPP), which is used for connection on the phone line.
Program
An integrated set of coded commands to your
computers telling your hardware what to do and how
and when to do it.
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.
SD
See Secure Digital.
SDRAM
Synchronous Dynamic Random Access Memory.
Secure Digital
A Secure Digital (SD) card is a small memory card that
allows portable storage among a variety of devices, such
as cell phones, GPS systems, digital cameras, and PDAs.
SD cards transfer data quickly, with low battery
consumption. Like the memory stick, it uses flash
memory architecture. This means that a power source is
not required to retain data.
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.
106
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.
SPDIF
Sony Philips Digital Interface Format. The optical digital
audio format that allows you to download digital audio
onto a MiniDisc recorder or connect to your sound
system to play MP3 files with high fidelity sound.
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.
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. Standard that provides 800x600 pixel
resolution and a palette of 16M colors.
S-Video
Super Video. A component video system for driving a
TV or computer monitor.
System Clock
An oscillator of fixed precise frequency which
synchronizes the operation of the system and is counted
to provide time of day and date.
