noun Technical meaning of scsi (hardware, standard) (SCSI) /skuh'zee/, /sek'si/ The most popular processor-independent standard, via a parallel bus, for system-level interfacing between a computer and intelligent devices including hard disks, floppy disks, CD-ROM, printers, scanners, and many more. SCSI can connect multiple devices to a single SCSI adaptor (or "host adaptor") on the computer's bus. SCSI transfers bits in parallel and can operate in either asynchronous or synchronous modes. The synchronous transfer rate is up to 5MB/s. There must be at least one target and one initiator on the SCSI bus. SCSI connections normally use "single ended" drivers as opposed to differential drivers. Single ended SCSI can suport up to six metres of cable. Differential ended SCSI can support up to 25 metres of cable. SCSI was developed by Shugart Associates, which later became Seagate. SCSI was originally called SASI for "Shugart Associates System Interface" before it became a standard. Due to SCSI's inherent protocol flexibility, large support infrastructure, continued speed increases and the acceptance of SCSI Expanders in applications it is expected to hold its market. The original standard is now called "SCSI-1" to distinguish it from SCSI-2 and SCSI-3 which include specifications of Wide SCSI (a 16-bit bus) and Fast SCSI (10 MB/s transfer). SCSI-1 has been standardised as ANSI X3.131-1986 and ISO/IEC 9316. A problem with SCSI is the large number of different connectors allowed. Nowadays the trend is toward a 68-pin miniature D-type or "high density" connector (HD68) for Wide SCSI and a 50-pin version of the same connector (HD50) for 8-bit SCSI (Type 1-4, pin pitch 1.27 mm x 2.45 mm). 50-pin ribbon cable connectors are also popular for internal wiring (Type 5, pin pitch 2.54 mm x 2.54 mm). Apple Computer used a 25-pin connector on the Macintosh computer but this connector causes problems with high-speed equipment. Original SCSI implementations were highly incompatible with each other. 1
