SCSI

A Small Computer System Interface board that remains the preferred hardware to add to hypermedia computers. The main use is to connect the computer to auxiliary storage drives such as CD-ROM drives, auxiliary hard drives, computer tape drives, Bernoulli drives, Syquest drives, etc. Other devices such as CD-ROM recorders can be connected to the computer through the SCSI board. Major producers include Adaptec (800-050-7274) and Corel (800-772-6735). For a review of SCSI technology, see NewMedia, April 1, 1996, pp. 31-34. (See also RAID )

 

SCSI ( Small Computer System Interface ) Pronounced ‘scuzzy’.An industry standard for connecting peripheral devices and their controllers to a microprocessor.The SCSI defines both hardware and software standards for communication between a host computer and a peripheral.

Stands for "Small Computer System Interface." It's pronounced "scuzzy"; nothing else is acceptable -- that's just how it is. SCSI is a computer interface that can be used to attach things like hard drives and scanners to your computer. You can connect up to seven devices to a SCSI interface and get good performance from all of them. Overall, SCSI is faster than the other popular storage interface, IDE, especially the fastest type of SCSI, called Wide Ultra2. For more information on the differences between SCSI and IDE, please check the Help Center. The different SCSI types are listed below: SCSI-1: Uses an 8-bit bus, supports data transfer speeds of 4 MBps. SCSI-2: Uses a 50-pin connector instead of a 25-pin connector, and supports multiple devices. It is currently the most common type of SCSI. Data transfer speeds are typically around 5 MBps. Wide SCSI: Uses a wider cable (168 cable lines to 68 pins) to support 16-bit data transfers. Fast SCSI: Uses an 8-bit bus, but doubles the clock rate to support data transfer speeds of 10 MBps. Fast Wide SCSI: Uses a 16-bit bus and supports data transfer speeds of 20 MBps. Ultra SCSI: Uses an 8-bit bus, supports data rates of 20 MBps. SCSI-3: Uses a 16-bit bus, supports data rates of 40 MBps. Also called Ultra Wide SCSI. Ultra2 SCSI: Uses an 8-bit bus, supports data transfer speeds of 40 MBps. Wide Ultra2 SCSI: Uses a 16-bit bus, supports data transfer speeds of 80 MBps.
