ROM Read Only Memory: A type of memory which is commonly adapted to
computer systems in order to hold crucial data or programming code.
Such information is critical to booting and/or operating the system’s
basic functions. ROM is read-only which means that the system may
read information in from the memory and begin to use it, but cannot
modify or erase the information. ROMs retain their data content
without having power applied to them, and the same data is available
every time the device is powered on. A system or peripheral BIOS are
generally located in a ROM, or NVRAM.
SMTP Simple Message Transfer Protocol: This is a network communications
protocol used by several layers of network communications, including
email.
SPT Sectors Per Track: This field of the drive’s CHS geometry defines the
highest value for the sector.
striping Refers to the storage of sequential block data across multiple drives in
a RAID array group.
TCP/IP Transfer Control Protocol / Internet Protocol: This is a software
interface for drivers or APIs which provide networking services for a
machine.
UDMA Ultra DMA: A hard drive transfer specification with higher data rates
than its predecessor, DMA.
XOR eXclusive OR: This is a common, bit -wise logical operation performed
with two inputs, yielding one output. In RAID applications, the known
results of this operation allows for reconstruction of data supplied as
input to XOR, and the output is used to generate parity.
