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.
SSD — Solid-state drive.
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.
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. Also referred to as the planar or motherboard.
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.
TB — Terabyte(s); 1024 gigabytes or 1,099,511,627,776 bytes. However, when
referring to hard-drive capacity, the term is usually rounded to 1,000,000,000,000
bytes.
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.
