SCSI
Acronym for small computer system interface. An intelligent interface device that expands a microprocessor (CPU) bus to facilitate connections to multiple peripherals (e.g., CD-ROM drives, hard drives, or scanners) and exchange data with those peripherals via a separate communications bus. Note 1: The original SCSI was capable of supporting up to 7 devices at a data rate of 5 Mb/s over an 8-bit parallel bus. Subsequent SCSI versions feature a parallel communications bus having greater width and speed. Note 2: Since SCSI exchanges data with the peripherals over a separate communications bus rather than the processor bus, the CPU can devote the saved processing time to other tasks. Note 3: Pronounced "scuzzy."
