Appendix A

Glossary of Terms and

Abbreviations

160/m	An industry initiative extension of the Ultra160 SCSI speciﬁcation that
	requires support of Double Transition Clocking, Domain Validation, and
	Cyclic Redundancy Check (CRC).
Active	The electrical connection required at each end of the SCSI bus,
Termination	composed of active voltage regulation and a set of termination resistors.
	Ultra, Ultra2, and Ultra160 SCSI require active termination.
Address	A speciﬁc location in memory, designated either numerically or by a
	symbolic name.
AIP	Asynchronous Information Protection provides error checking for
	asynchronous, nondata phases of the SCSI bus.
Asynchronous	One of the ways data is transferred over the SCSI bus. It is slower than
Data Transfer	synchronous data transfer.
BIOS	Basic Input/Output System. Software that provides basic read/write
	capability. Usually kept as ﬁrmware (ROM based). The system BIOS on
	the mainboard of a computer is used to boot and control the system. The
	SCSI BIOS on your host adapter acts as an extension of the system
	BIOS.
Bit	A binary digit. The smallest unit of information a computer uses. The
	value of a bit (0 or 1) represents a two-way choice, such as on or off,
	true or false, and so on.
Bus	A collection of unbroken signal lines across which information is
	transmitted from one part of a computer system to another. Connections
	to the bus are made using taps on the lines.
