A.
4

B.
7

C.
15

D.
127

Explanation:

A Fast-Wide SCSI-2 bus supports 15 devices excluding the SCSI adapter. Fast-Wide SCSI-2 has a 16-bit
bus. The adapter is usually preset to
ID 7.
SCSI-1 and Fast SCSI-2 have an 8-bit bus with device numbers ranging from 0 to 7, including the SCSI

What is SCSI? Hide
Small Computer System Interface (SCSI) is the second most popular drive interface in use today after
the Integrated Drive
Electronics (IDE) interface. SCSI is faster than IDE and supports more devices. SCSI devices, such as
hard disk drive and
CD-ROM drive, are better suited in a network environment in which many users access shared drives
simultaneously. SCSI

has three standards: SCSI-1, SCSI-2, and SCSI-3.
