Glossary

adapter

A device, usually in the form of a user interface card, that physically connects a computer to the SCSI bus. Also referred to as a host adapter.

ANSI (American National Standards Institute)

Organization which coordinates, develops and publishes standards used in the United States.

asynchronous transmission

A data transmission technique where the initiator and the target lock into a transfer of data, each block of data must be acknowledged before the next block is transmitted.

Attenuation

Signal power lost in a transmission medium as the signal travels from sender to receiver.

Bus Device Reset

A SCSI message to a target that instructs the target to clear all activity.

Byte

An eight-bit unit of data. It is usually the smallest addressable unit in memory.

CBR (Constant Bit Rate)

The transmission of bits at a fixed rate over a network or over a communications bus.

CCB (Command Control Block)

A block of information prepared by the host computer, for the SCSI adapter, to provide the adapter with parameters needed to execute a SCSI command.
