Parallel Advanced Technology Attachment (PATA) is an interface designed to accommodate mass storage devices for computers. PATA was formerly called IDE (Integrated Device Electronics) and EIDE (Enhanced IDE). Until recent years, PATA/IDE/EIDE storage devices (hard drives, CD and DVD Drives) were nearly universal in PCs. (SCSI was and is still around, but in very limited use.)

About ten years ago, a new standard -- SATA, or Serial ATA -- was introduced for mass storage devices. By 2008, SATA had largely taken over as the new standard for hard drives, and it has since conquered the CD/DVD market also.

But there are still many millions of PATA legacy drives and boards in use, and PATA devices and boards continue to be sold today, though in greatly reduced quantity. (The PC I'm using as I write this has a mainboard with both PATA and SATA interfaces, and all the mass storage drives are PATA. Why would I go out and buy new drives?)
