, or 2
30
. This is the definition often used
in computer science, computer programming, and in the majority of computer
operating systems documentation. This measurement can be abbreviated as GiB
(gibibyte) to avoid ambiguity, as defined in IEC 60027-2.
Note: For the purpose of this document we are using SI.
GS German Safety.
H
Head The tiny electromagnetic coil and metal pole used to create and read back
the magnetic patterns on the media. Also known as the read/write head.
HiFN An ASIC (Application Specific Integrated Circuit) for the system that
handles data compression.
HIM The Host Interface Module implements the interface between the host
system and the tape drive.
HRE Hard Read Error.
HWE Hard Write Error.
I
ICM The Integrated Controller Module contains the main controller and servo
microprocessor, the custom-designed ASICs, and the cache memory.
IEC The International Electrotechnical Commission is a standards organization
that prepares and publishes international standards for all electrical, electronic,
and related technologies.
IEEE Institute of Electrical and Electronics Engineers
Interface A hardware or software protocol—contained in the electronics of the
media controller and tape drive—that manages the exchange of data between the
tape drive and computer. The most common interfaces for small computer
systems are AT (IDE) and SCSI.
ISO The International Organization for Standardization is an international non-
governmental standard-setting body made up of representatives from national
standards bodies.
ISV Independent Software Vendor.
J
Jumper A tiny connector box that slips over two pins that protrude from a circuit
board. While in place, the jumper connects the pins electrically. The jumper can be
moved to change electrical connections.
