Final answer:
Option B. 16. A SCSI Wide Bus can connect up to 16 devices, which is consistent with its 16-bit width that facilitates parallel data transfer.
Step-by-step explanation:
The maximum number of devices that can be connected to a SCSI Wide Bus is 16. SCSI, which stands for Small Computer System Interface, is a set of standards for connecting and transferring data between computers and peripheral devices. The 'Wide' in SCSI Wide Bus refers to the bus's width in terms of the number of bits that can be transferred simultaneously, which in this standard is 16 bits. Therefore, a Wide SCSI bus can support up to 16 devices, including the host adapter.
The maximum number of devices that can be connected to a SCSI Wide Bus depends on the version of SCSI. The original SCSI standard allowed for up to 8 devices to be connected to a single bus. However, with the introduction of SCSI Wide, the number of devices that could be connected increased significantly. SCSI Wide allows for up to 16 devices to be connected to a single bus.
