How many devices, excluding the SCSI adapter, does a Fast-Wide SCSI-2 bus support?

The correct answer is C. 15. 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 adapter and seven other devices…

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 adapter and seven other devices. 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.
