Device
According to the SCSI specification, multiple SCSI devices can
be connected to a single SCSI bus. Each SCSI device contains a
SCSI ID number that can be set in the range 0 to 15.
Device Driver
A low-level (usually kernel-mode) operating system component
that enables a PC to communicate with peripheral devices such as
printers, CD-ROMs, and tape drives. Each kind of device
requires a different driver.
Differential
A term referring to the electrical characteristics of the signal used
on the SCSI bus interface. Differential signals minimize the
effect of common mode signal noise and allow the SCSI bus to
operate reliably over greater distances at a higher speed.
DLTSage
A suite of predictive and preventive maintenance diagnostics
software, sold and supported by Quantum Corporation.
DLZ
Digital Lempel-Ziv 1 Algorithm. Named after Abraham Lempel
and Jacob Ziv. A data compression technique used in all SDLT
tape drives.
EEPROM
Electronically Erasable Programmable Read-Only Memory. An
integrated circuit memory chip that can store programs and data
in a non-volatile state. These devices store firmware in DLT and
SDLT tape drives, and can be erased and reprogrammed with
new data.
EIM
Electronic Interface Module. The SDLT EIM consists of two
major boards—the Integrated Controller Module (ICM) board
and a separate Host Interface Module (HIM) board.
Encoding
(n.) Characters (or bytes) of information converted to magnetic
patterns on the media. (v.) The process of converting to the
desired pattern.
EOD
End of Data. Location on media where the last session stopped.
EOM or EOT
End of Media or End of Tape. Logical EOM allows space to
complete a write operation; physical EOM signifies that the
media is completely used.
Erase
The removal of data from media.
