hardware. Typically, readme files provide installation information, describe new product enhancements or corrections that have not yet been documented, and
list known problems or other things you need to be aware of as you use the software or hardware.
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.
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 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.
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.
Striping
Disk striping writes data across 3 or more array disks. Each "stripe" spans 3 or more array disks but only consumes a portion of each disk. The amount of
space consumed by a stripe is the same on each array disk included in the stripe. A virtual disk may use several stripes on the same set of array disks.
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.
system board
As the main circuit board, the system board usually contains most of your system's integral components, such as the following:
