SCSI系列标准提供了许多不同的传输协议，这些协议定义了不同SCSI设备之间交换信息的规则。本标准定义了使用串行互连在SCSI设备之间交换信息的规则。其他SCSI传输协议标准定义了使用其他互连在SCSI设备之间交换信息的规则。本标准还定义了使用相同串行互连在ATA主机和ATA设备之间交换信息的规则。其他ATA传输协议标准定义了使用其他互连在ATA主机和ATA设备之间交换信息的规则。

The SCSI family of standards provides for many different transport protocols that define the rules for exchanging information between different SCSI devices. This standard defines the rules for exchanging information between SCSI devices using a serial interconnect. Other SCSI transport protocol standards define the rules for exchanging information between SCSI devices using other interconnects.This standard also defines the rules for exchanging information between ATA hosts and ATA devices using the same serial interconnect. Other ATA transport protocol standards define the rules for exchanging information between ATA hosts and ATA devices using other interconnects.
