SCSI（小型计算机系统接口）标准集由本标准和1.3中描述的SCSI实施标准组成。本标准定义了一个用于指定SCSI设备常见行为的参考模型，以及一个通用于所有SCSI I/O系统实现的抽象结构。 这套SCSI标准规定了确保一致的SCSI实现之间的互操作性所需的接口、功能和操作。本标准为功能说明。一致性实现可以使用任何不违反互操作性的设计技术。

The set of SCSI (Small Computer System Interface) standards consists of this standard and the SCSI implementation standards described in 1.3. This standard defines a reference model that specifies common behaviors for SCSI devices, and an abstract structure that is generic to all SCSI I/O system implementations. The set of SCSI standards specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This standard is a functional description. Conforming implementations may employ any design technique that does not violate interoperability.
