Question

Comprehension

Comprehension: Questions concern a disk with a sector size of 512 bytes, 2000 tracks per surface, 50 sectors per track, five double-sided platters, and average seek time of 10 milliseconds.

Given below are two statements:

Statement I: The disk has a total number of 2000 cylinders.

Statement II: 51200 bytes is not a valid block size for the disk.

In the light of the above statements, choose the correct answer from the options given below:

1. Both Statement I and Statement II are true
2. Both Statement I and Statement II are false
3. Statement I is correct but Statement II is false
4. Statement I is incorrect but Statement II is true

Answer 1

Correct Answer - Option 1 : Both Statement I and Statement II are true

The correct answer is option 1. 

Statement I: correct.

The number of cylinders is 2000, which is the same as the number of tracks on each platter.

Hence it is correct.

Statement II: correct

The block size will be a multiple of the sector size. 51200 is not a valid block size in this case because block size cannot exceed the size of a track, which is 25600 bytes.

Hence it is correct.
