Which command of DOS is used to compare two floppy disks? A. DISKCOPY B. DISKCOMP C. DISKCOPY A: B/V D. FORMAT A: B: E. None of the above

The correct answer is: B. DISKCOMP

DISKCOMP is a DOS command that compares the contents of two floppy disks. It is used to verify that the two disks are identical. To use DISKCOMP, you must specify the drive letters of the two disks that you want to compare. For example, to compare the contents of floppy disk A with the contents of floppy disk B, you would type the following command:

DISKCOMP A: B:

DISKCOMP will then compare the two disks and report any differences. If the two disks are identical, DISKCOMP will report “Compare OK.” If the two disks are not identical, DISKCOMP will report the differences between the two disks.

The other options are incorrect for the following reasons:

• A. DISKCOPY is a DOS command that copies the contents of one floppy disk to another. It is not used to compare two floppy disks.
• C. DISKCOPY A: B/V is a variation of the DISKCOPY command that verifies the copy as it is being made. It is not used to compare two floppy disks.
• D. FORMAT A: B: is a DOS command that formats two floppy disks. It is not used to compare two floppy disks.
• E. None of the above is the correct answer.
