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.
