SCSI ports (pronounced 70-649 "scuzzy") are for transmitting fast data to up to seven devices in a daisy chain. SCSI stands for "small computer system interface". Personal computers are able to communicate with hardware such as disk drives, tape drives, CD-ROM drives, printers and scanners much quicker. The current set of SCSIs are parallel interfaces that were developed at Apple Computer and are still used in the Macintosh today. SCSI ports continue to be built into PCs today, and as such, are supported by all major VCP-310 operating systems.
SCSI is also more flexible than previous parallel data transfer interfaces. Ultra-2 SCSI can transfer data up to eighty megabytes per second. Seven to fifteen devices can be connected to one SCSI port in the daisy-chain fashion, dependent on the bus width. One circuit board or card can accommodate all the peripherals.
The original SCSI is known as SCSI-1, which evolved into SCSI-2, also known as "plain SCSI" because it VCP-101V became widely accepted. SCSI-3 has extra specialized command sets that meet the needs of specific device types.
