Term:SATA [Serial ATA]
SATA is short for “Serial ATA”. ATA is short for “AT Attachment”. AT, in turn, derives from the original IBM PC/AT, where AT stood for “Advanced Technology”.
SATA is a type of physical-data-transfer interface, and is most commonly associated with disk drives. In addition to the electrical characteristics of the interface, SATA also defines the techniques actually used to transfer data, as well as the physical characteristics of the connectors used for supported devices.
The SATA interface replaced the earlier ATA or Parallel ATA (PATA) interface, also often known as EIDE.

Serial ATA (SATA, abbreviated from Serial AT Attachment) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives. Serial ATA succeeded the earlier Parallel ATA (PATA) standard to become the predominant interface for storage devices.
Serial ATA industry compatibility specifications originate from the Serial ATA International Organization (SATA-IO) which are then promulgated by the INCITS Technical Committee T13, AT Attachment (INCITS T13).
