RPM - revolutions per minute - The number of rotations that occur per minute. Hard drive speed is often measured in rpm. RTC - real time clock - Battery-powered clock on the system board that keeps the date and time after you shut down the computer. RTCRST - real-time clock reset - A jumper on the system board of some computers that can often be used for troubleshooting problems. S SAS - serial attached SCSI - A faster, serial version of the SCSI interface (as opposed to the original SCSI parallel architecture). 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. 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. 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. 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. 166 Glossary

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.
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.
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.
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.
