Other definitions of SCSI

(Small Computer Systems Interface; pr. ‘scuzzy’) A system for controlling hard disks, tape drives, and various other add-ons. Sometimes used for a PC’s main hard disk, but more often the main hard disk is controlled by an- EIDE- controller built into the motherboard. A SCSI controller would usually be installed as an expansion board. SCSI is a bit faster than EIDE, but more expensive.
