- IDE
Intelligent Device Electronics (formerly Integrated Drive Electronics). The built-in system a PC computer uses to connect drives to the computer. You may have also heard it called ATA (Advanced Technology Attachment)
they mean the same thing. IDE can support two devices per channel with data transfer rates of 16.67 MB/s. The IDE interface has now been enhanced to support faster data transfers. See DMA for more information.
There are usually two places on the motherboard for the IDE cables to connect. These are the primary and secondary IDE channel connections. The hard drive usually uses the primary connection. The IDE channel connections are usually located next to each other either end-to-end or one above the other. They are also generally labeled on the motherboard as "pri IDE" and "sec IDE" or something similar. If you are unsure of where the IDE channels for your computer are located, refer to your computer's documentation or local computer retailer. These channels can support a maximum of two drives each. If there are two drives connected to the IDE interface cable, one drive must be configured as a master and the other as a slave. If only one drive is attached to the cable, it is configured as a master.

- ISA
Industry Standard Architecture. An internal connection for devices such as network cards, SCSI cards, video cards, sound cards, etc. ISA has a maximum data transfer rate of 8.3 MB/s. ISA will eventually be replaced by PCI.
- ISO 9660
The ISO document titled ISO 9660: Information Processing—Volume and File Structure of CD-ROM for Information Exchange (1988) defines a CD format that can be read by many different operating systems, including Mac® OS, Windows®, DOS, UNIX, etc. ISO 9660 does not support long file names, custom icons, or directory settings. Discs intended only for Macintosh users should be written in the HFS format.
