Which of the following is the bandwidth of an SCSI Ultra2 Wide I/O port?
A.
320 MBps
B.
80 MBps
C.
50 MBps
D.
160 MBps
Explanation:
The SCSI Ultra2 Wide I/O port has a bandwidth of 80 MBps.
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 drives
and CD-ROM drives, are better suited to a network environment in which many users access shared
drives simultaneously. SCSI has three standards: SCSI-1, SCSI-2, and SCSI-3.
Answer C is incorrect. The IEEE 1394a S400 I/O port has a bandwidth of 50 MBps.
Answer D is incorrect. The SCSI Ultra3 I/O port has a bandwidth of 160 MBps.
Answer A is incorrect. The SCSI Ultra4 port has a bandwidth of 320 MBps.
