ROM - read-only memory - Memory that stores data and programs that cannot be deleted or written to by the computer. ROM, unlike RAM, retains its contents after you shut down your computer. Some programs essential to the operation of your computer reside in ROM. 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. 210 Glossary
