134 Glossary
SATA — serial ATA — A faster, serial version of the ATA
(IDE) interface.
ScanDisk — A Microsoft utility that checks files, folders,
and the hard disk’s surface for errors. ScanDisk often runs
when you restart the computer after it has stopped
responding.
SCSI — small computer system interface — A high-speed
interface used to connect devices to a computer, such as
hard drives, CD drives, printers, and scanners. The SCSI
can connect many devices using a single controller. Each
device is accessed by an individual identification number
on the SCSI controller bus.
SDRAM — synchronous dynamic random-access memory
— A type of DRAM that is synchronized with the optimal
clock speed of the processor.
serial connector — An I/O port often used to connect
devices such as a handheld digital device or digital camera
to your computer.
Service Tag — A bar code label on your computer that
identifies your computer when you access Dell Support at
support.dell.com or when you call Dell for customer
service or technical support.
setup program — A program that is used to install and
configure hardware and software. The setup.exe or
install.exe program comes with most Windows software
packages. Setup program differs from system setup.
shortcut — An icon that provides quick access to
frequently used programs, files, folders, and drives. When
you place a shortcut on your Windows desktop and
double-click the icon, you can open its corresponding
folder or file without having to find it first. Shortcut icons
do not change the location of files. If you delete a
shortcut, the original file is not affected. Also, you can
rename a shortcut icon.
smart card — A card that is embedded with a processor and
a memory chip. Smart cards can be used to authenticate a
user on computers equipped for smart cards.
S/PDIF — Sony/Philips Digital Interface — An audio
transfer file format that allows the transfer of audio from
one file to another without converting it to and from an
analog format, which could degrade the quality of the file.
standby mode — A power management mode that shuts
down all unnecessary computer operations to save energy.
Strike Zone™ — Reinforced area of the platform base
that protects the hard drive by acting as a dampening
device when a computer experiences resonating shock or
is dropped (whether the computer is on or off).
surge protectors — Prevent voltage spikes, such as those
that may occur during an electrical storm, from entering
the computer through the electrical outlet. Surge
protectors do not protect against lightning strikes or against
brownouts, which occur when the voltage drops more than
20 percent below the normal AC-line voltage level.
Network connections cannot be protected by surge
protectors. Always disconnect the network cable from the
network connector during electrical storms.
SIM — Subscriber Identity Module. A SIM card contains
a microchip that encrypts voice and data transmissions.
SIM cards can be used in phones or portable computers.
SVGA — super-video graphics array — A video standard
for video cards and controllers. Typical SVGA resolutions
are 800 x 600 and 1024 x 768.
The number of colors and resolution that a program
displays depends on the capabilities of the monitor, the
video controller and its drivers, and the amount of video
memory installed in the computer.
S-video TV-out — A connector used to attach a TV or
digital audio device to the computer.
SXGA — super-extended graphics array — A video
standard for video cards and controllers that supports
resolutions up to 1280 x 1024.
SXGA+
— super-extended graphics array plus — A video
standard for video cards and controllers that supports
resolutions up to 1400 x 1050.
system board — The main circuit board in your computer.
Also known as the motherboard.
system setup — A utility that serves as an interface
between the computer hardware and the operating
system. System setup allows you to configure user-
selectable options in the BIOS, such as date and time or
system password. Unless you understand what effect the
settings have on the computer, do not change the settings
for this program.
