SCSI

SCSI (pronounced "scuzzy") is an acronym for the small computer system interface. SCSI is a protocol used primarily for data transfer between hosts and storage devices.

SCSI originally was designed for use with a bus, with many hosts and many devices all attached over a single parallel SCSI cable. This implementation, though still used, is becoming less and less frequent as serial technologies such as SATA (Serial Advanced Technology Attachment), SAS (Serial Attached SCSI) and Fibre Channel are becoming more and more popular within enterprise and consumer level storage devices.
