IDE Integrated Drive Electronics

A standard interface for IBM-compatible hard drives. IDE is different from the Small Computer Systems Interface (SCSI) and Enhanced Small Device Interface (ESDI). IDE controllers are on each drive, meaning the drive can connect directly to the motherboard or controller. IDE and its updated successor, Enhanced IDE (EIDE), are the most common interfaces for the drives that are found in IBM compatible computers today. Also called ATA (Advanced Technology Attachment)
