SCSI (small computer system interface) A specification for a high-performance peripheral bus and command set. The original standard is now referred to as SCSI-1.

SCSI-2The current SCSI specification that adds features to the original SCSI-1 standard.

SCSI-3The next SCSI specification, that adds features to the SCSI-2 standard.

SCSI bus A host adapter and one or more SCSI peripherals connected by cables in a linear chain configuration. The host adapter may exist anywhere on the chain, allowing connection of both internal and external SCSI devices. A system may have more than one SCSI bus by using multiple host adapters.

SCSI device Any device conforming to the SCSI standard that attaches to the SCSI bus by means of a SCSI cable. This includes SCSI host adapters and SCSI peripherals.

SCSI ID A unique identification for each SCSI device on the SCSI bus. Each SCSI bus has fifteen available SCSI IDs numbered 0 through 15 for Wide SCSI or 0-7 for 8-bit SCSI. The host adapter is assigned ID 7, which gives it priority to control the bus.

SDMS (SCSI Device Management System) A Symbios software product that manages SCSI system I/O.

single-ended SCSI A hardware specification for connecting SCSI devices. It references each SCSI signal to a common ground, as opposed to differential SCSI and low-voltage differential SCSI, which use a separate return for each signal.

synchronous data transfer

One of the ways data is transferred over the SCSI bus. Transfers are clocked with fixed-frequency pulses.

System BIOS Controls the low level POST (Power On Self Test) and basic operation of the CPU and computer system.

termination The electrical connection required at each end of the SCSI bus, composed of a set of resistors.

Ultra SCSI A standard for SCSI data transfers. It allows a transfer rate of up to 20 MBytes/sec over an 8-bit SCSI bus, and up to 40 MBytes/sec over a 16-bit SCSI bus. STA (SCSI Trade Association) supports using the term “Ultra SCSI” over the older term “Fast-20.”

Ultra2 SCSI A standard for SCSI data transfers. It allows a transfer
