Dell PowerEdge R210 - Manual (Page 15)

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.
system board — As the main circuit board, the system board usually contains most of your system's integral components, such as the processor(s), RAM,
controllers for peripherals, and various ROM chips.
system configuration information — Data stored in memory that tells a system what hardware 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 your system's hardware and customize the system's operation by setting
features such as password protection. Because the System Setup program is stored in NVRAM, any settings remain in effect until you change them again.
TCP/IP — Transmission Control Protocol/Internet Protocol.
termination — Some devices (such as the last device at each end of a SCSI cable) must be terminated to prevent reflections and spurious signals in the cable.
When such devices are connected in a series, you may need to enable or disable the termination on these devices by changing jumper or switch settings on
the devices or by changing settings in the configuration software for the devices.
TOE — TCP/IP offload engine.
U-DIMM — An unregistered (unbuffered) DDR3 memory module.
uplink port — A port on a network hub or switch used to connect to other hubs or switches without requiring a crossover cable.
UPS — Uninterruptible power supply. A battery-powered unit that automatically supplies power to your system in the event of an electrical failure.
USB — Universal Serial Bus. A USB connector provides a single connection point for multiple USB-compliant devices, such as mice and keyboards. USB devices
can be connected and disconnected while the system is running.
USB memory key — See memory key.
utility — A program used to manage system resources—memory, disk drives, or printers, for example.
V — Volt(s).
VAC — Volt(s) alternating current.
VDC — Volt(s) direct current.
VGA — Video graphics array. VGA and SVGA are video standards for video adapters with greater resolution and color display capabilities than previous
standards.
video adapter — The logical circuitry that provides (in combination with the monitor) your system's video capabilities. A video adapter may be integrated into
the system board or may be an expansion card that plugs into an expansion slot.
video memory — Most VGA and SVGA video adapters include memory chips in addition to your system's RAM. The amount of video memory installed primarily
influences the number of colors that a program can display (with the appropriate video drivers and monitor capabilities).
video resolution — Video resolution (800 x 600, for example) is expressed as the number of pixels across by the number of pixels up and down. To display a
program at a specific graphics resolution, you must install the appropriate video drivers and your monitor must support the resolution.
virtualization — The ability via software to share the resources of a single computer across multiple environments. A single physical system may appear to the
user as multiple virtual systems able to host multiple operating systems.
W — Watt(s).
