Glossary 197SAS — Serial-attached SCSI.SATA — Serial Advanced Technology Attachment. A standard interface between thesystem board and storage devices.SCSI — Small computer system interface. An I/O bus interface.SD card — Secure digital flash memory card.SDDC — Single device data correction.SDRAM — Synchronous dynamic random-access memory.sec — Second(s).serial port — A legacy I/O port with a 9-pin connector that transfers data one bit at atime and is most often used to connect a modem to the system.service tag — A bar code label on the system used to identify it when you call Dell fortechnical support.SMART — Self-Monitoring Analysis and Reporting Technology.

The amount of space used by a "stripe" is thesame on each disk used. A virtual disk may use several stripes on the same set of disksin an array. See also guarding, mirroring, and RAID.system board — As the main circuit board, the system board usually contains most ofyour system’s integral components, such as the processor(s), RAM, controllers forperipherals, and various ROM chips.system configuration information — Data stored in memory that tells a system whathardware is installed and how the system should be configured for operation.system memory — See RAM.System Setup program — A BIOS-based program that allows you to configure yoursystem’s hardware and customize the system’s operation by setting features such aspassword protection. Because the System Setup program is stored in NVRAM, anysettings remain in effect until you change them again.
