Acronym for Small Computer System Interface, a standard high-speed parallel interface defined by the X3T9.2 committee of the American National Standards Institute (ANSI). A SCSI (pronounced “scuzzy”) interface is used to connect microcomputers to SCSI peripheral devices, such as many hard disks and printers, and to other computers and local area networks. Also called: SCSI-1, SCSI I. Compare ESDI, IDE.r /> Small Computer System Interface: (pronounced scuzzi) is an agreed upon standard of how peripherals such as printers, hard drives, and other items may be attached to a computer. Collaboration on this standard allows for devices made by different manufacturers to communicate with each other. There are different types of SCSI reflecting extensions to the standard to accommodate wider data buses and faster transfer rates as technology has advanced.
(abbreviation for small computer system interface) In computing, a parallel interface used by the Apple Macintosh and an increasing number of MS-DOS-based personal computers for the connection of devices such as disc drives, printers, and CD-ROM drives. SCSI can support high data transfer rates. A new version, SCSI-2, can support even higher transfer rates.
