An operating mode supported by 80286 or higher microprocessors, real mode imitates the architecture of an 8086 microprocessor.

ROM

Acronym for read-only memory. Your system contains some programs essential to its operation in ROM code. Unlike RAM, 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

Acronym for RAID on Motherboard.

rpm

Abbreviation for revolutions per minute.

RTC

Abbreviation for real-time clock. Battery-powered clock circuitry inside the system that keeps the date and time after you turn off the system.

SA

Abbreviation for server appliance.

SCSI

Acronym for small computer system interface. An I/O bus interface with faster data transmission rates than standard ports. You can connect up to seven
devices (15 for some newer SCSI types) to one SCSI interface.

SDMS

Abbreviation for SCSI device management system.

SDRAM

Acronym for synchronous dynamic random-access memory.

sec

Abbreviation for second(s).

serial port

An I/O port used most often to connect a modem to your system. You can usually identify a serial port on your system by its 9-pin connector.

service tag number

A bar code label on the system that identifies it when you call Dell for customer or technical support.

SIMM

Acronym for single in-line memory module. A small circuit board containing DRAM chips that connects to the system board.

SMART

Acronym for Self-Monitoring Analysis and Reporting Technology. A technology that allows hard drives to report errors and failures to the system BIOS, which
then displays an error message on the screen. To take advantage of this technology, you must have a SMART-compliant hard drive and the proper support in
the system BIOS.

SMP

Abbreviation for symmetric multiprocessing. SMP is a system that has two or more microprocessors connected via a high-bandwidth link and managed by an
operating system, where each microprocessor has equal access to I/O devices. This is in contrast to parallel processing, where a front-end microprocessor
handles all I/O to disks, terminals, local area networks, and so on.

SNMP

Abbreviation for Simple Network Management Protocol. SNMP is an industry-standard interface that allows a network manager to remotely monitor and
manage workstations.

SRAM

Abbreviation for static random-access memory. Because SRAM chips do not require continual refreshing, they are substantially faster than DRAM chips.

SVGA

Abbreviation for super video graphics array. VGA and SVGA are video standards for video adapters with greater resolution and color display capabilities than
previous standards.

To display a program at a specific resolution, you must install the appropriate video drivers and your monitor must support the resolution. Similarly, the number
of colors that a program can display depends on the capabilities of the monitor, the video driver, and the amount of video memory installed in the system.
