SCSI (pronounced SKUH-zee), the Small Computer System Interface, is a set of evolving American National Standards Interface (ANSI) standard electronic interfaces that allow personal computers to communicate with peripheral hardware such as disk drives, tape drives, CD-ROM drives, printers and scanners faster and more flexibly than previous interfaces. Originally developed at Apple Computer, the present set of SCSIs are defined for parallel interfaces. The latest SCSI standard is Ultra-3 (sometimes spelled “Ultra3”), which increases the maximum burst rate from 80 Mbps to 160 Mbps by being able to operate at the full clock rate rather than the half-clock rate of Ultra-2. The standard is also sometimes referred to as Ultra160/m. Disk drives supporting Ultra160/m offer much faster data transfer rates. Ultra160/m also includes cyclical redundancy checking (CRC) for ensuring the integrity of transferred data and domain validation for testing the SCSI network. In addition to faster data rates
