ATA : Computer Hardware Buyers’ Glossary


ATA (Advanced Technology Attachment) is the intreface specification for IDE (Integrated Drive Electronics) disks, named after the PC/AT where IBM (International Business Machines) first used these things.) There a couple of improvements on the ATA standard to support larger disks, non-disk devices, and higher speeds. They named ATA-2 and ATA-3. Ultra-ATA and ATA-4 are in the works, but may have been dropped now that SATA (Serial ATA) has taken over. Now called PATA (Parallel ATA), to more carefully distinguish it from SATA.
