ANSI INCITS 451
- Information Technology â€“ AT Attachment-8 â€“ ATA/ATAPI Architecture Model(ATA8-AAM)
The set of AT Attachment standards consists of this standard and the ATA implementation standards described in 1.3. This standard defines a reference model that defines common behaviors for ATA hosts and devices and an abstract structure that is generic to all ATA I/O system implementations.
The set of ATA standards defines the interfaces, functions, and operations necessary to ensure interoperability between conforming ATA implementations. This standard is a functional description. Conforming implementations may employ any design technique that does not violate the requirements of this standard.
