SCSI (Small Computer System Interface)

A standard way of interfacing a computer to disk drives and other devices that require high-speed data transfer. Up to 16 SCSI devices, including the host adapter, can be connected in a daisy chain fashion. These devices can be hard disk drives, CD-ROMs, scanners, or printers. SCSI is the only common computer interface that allows adding both internal and external devices on the same chain. (Pronounced "scuzzy.")
