7 Glossary of Terms
Active Termination
Enhanced SCSI termination that provides better stability and noise
immunity of the electrical signals on the SCSI-bus lines.
ALDC
Adaptive Lossless Data Compression. A hardware data compression
method.
ASPI
Advanced SCSI Programming Interface. Standard SCSI software that acts
as a liaison between host adapters and SCSI device drivers. ASPI enables
host adapters and device drivers to share a single SCSI hardware interface.
Auto sensing
220LTO, LTO-2 HH feature that allow detection of the best transfer rate
to use for optimizing performance on the SCSI-bus.
Data Compression
There are two ways to compress data on tape. Through the software data
compression or using hardware data compression as on the Tandberg
LTO HH
Device Driver
A software program that enables a computer to communicate with
peripheral devices such as a hard disk or tape drives. Each type of device
needs a different device driver. Device drivers are stored on a computer's
hard disk and are typically loaded into memory at boot time.
EEPROM
Electrically Erasable Programmable Read Only. An integrated circuit
typically used to store configuration information.
GUI
Graphical User Interface. Software which interacts with the user.
ID
See SCSI-ID.
LVD
Low Voltage Differential. LVD provides better stability and noise
immunity of the electrical signals on the SCSI-bus lines. LVD also
allows longer SCSI Bus length.
Overwrite
A method of recording over data previously written on tape without
performing a erase operation before.
PNP
Plug and Play. A hardware and software mechanism that provides an
automatic way for the system to self-configure system resources such as I/O
ports, IRQ, and DMA channels between PNP cards and other devices in the
system.
RWW
Read While Write. All Tandberg tape drives automatically and internally read
the data just being written to the tape to avoid writing to bad block.
