Glossary 141

ROM — Read-only memory. Your system contains some programs essential to its

operation in ROM code. A ROM chip retains its contents even after you turn off your

system. Examples of code in ROM include the program that initiates your system’s

boot routine and the POST.

ROMB — RAID on motherboard.

SAN — Storage Area Network. A network architecture that enables remote network-

attached storage devices to appear to a server to be locally attached.

SAS — Serial-attached SCSI.

SATA — Serial Advanced Technology Attachment. A standard interface between the

system board and storage devices.

SCSI — Small computer system interface. An I/O bus interface with faster data

transmission rates than standard ports.

SD card — Secure digital flash memory card.

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 a

time 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 for

technical support.

SMART — Self-Monitoring Analysis and Reporting Technology. Allows hard drives to

report errors and failures to the system BIOS and then display an error message on the

screen.

SMP — Symmetric multiprocessing. Used to describe a system that has two or more

processors connected via a high-bandwidth link and managed by an operating system,

where each processor has equal access to I/O devices.

SNMP — Simple Network Management Protocol. A standard interface that allows a

network manager to remotely monitor and manage workstations.

striping — Disk striping writes data across three or more disks in an array, but only

uses a portion of the space on each disk. The amount of space used by a "stripe" is the

same on each disk used. A virtual disk may use several stripes on the same set of disks

in an array. See also guarding, mirroring, and RAID.

SVGA — Super video graphics array. VGA and SVGA are video standards for video

adapters with greater resolution and color display capabilities than previous standards.
