  SCSI-2
       
           A version of the {SCSI} command
          specification.
       
          SCSI-2 shares the original SCSI's {asynchronous} and


          {synchronous} modes and adds a "{Fast SCSI}" mode (<10MB/s)
          and "{Wide SCSI}" (16 bit, <20MB/s or rarely 32 bit).
       
          Another major enhancement was the definition of command sets
          for different device classes.  SCSI-1 was rather minimalistic
          in this respect which led to various incompatibilities
          especially for devices other than {hard-disk}s.  SCSI-2
          addresses that problem. allowing {scanner}s, {hard disk
          drive}s, {CD-ROM} drives, tapes and many other devices to be
          connected.
       
          Normal SCSI-2 equipment (not wide or {differential}) can be
          connected to a SCSI-1 bus and vice versa.
