IDE is a keyword points to the semi-conductors on the mother-board that controls ATA Drives(like ATA Hard-Disks). ATA (AT-Attachment) is the interface of this drives. IDE also can be an IDE card connected to PCI.
ATAPI is an extension to ATA. ATAPI (ATA Packet Interface) adds the support of Drives wich uses SCSI Command-Set (like ODDs (Optical Disk Drives .e.g CD-ROMs, DVD-ROMs), Tape Drives, and ZIP Drives).
Parallel/Serial ATA/ATAPI
IDE can allow even 4 drives to be connected to. the drive may be: 1. Parallel AT-Attachment [PATA]: Like PATA HDDs 2. Parallel AT-Attachment Packet-Interface [PATAPI]: Like PATAPI ODDs. 3. Serial ATA [SATA]: Like SATA HDDs. 4. Serial ATAPI [SATAPI]: Like SATAPI ODDs. We can ignore Tape Drives and ZIP Drives as they are obseleted. The Way of accessing ATA Drives is one, means that the way of accessing PATA HDDs is the same of SATA HDDs. also the way of accessing PATAPI ODDs is the same of SATAPI ODDs. for that, for IDE Device Driver, it is not required to know if a drive is Parallel or Serial, but it is important to know if it is ATA or ATAPI.
