Practice - 5 Tasks

1fill in blank

easy

Complete the sentence to explain why disk scheduling reduces seek time.

Operating Systems

Disk scheduling reduces seek time by [1] the order of disk access requests.

💡 Hint

Common Mistakes

Choosing 'randomizing' because it sounds like mixing up requests.

Choosing 'ignoring' because it seems like skipping requests.

Disk scheduling reduces seek time by optimizing the order in which disk access requests are handled, minimizing the movement of the disk's read/write head.

2fill in blank

medium

Complete the sentence to describe what disk scheduling minimizes.

Operating Systems

Disk scheduling minimizes the [1] time of the disk's read/write head.

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Confusing seek time with transfer time.

Choosing waiting time which is related but not the main focus.

Disk scheduling minimizes the seek time, which is the time taken for the disk's read/write head to move to the correct track.

3fill in blank

hard

Fix the error in the sentence about disk scheduling.

Operating Systems

Disk scheduling increases the [1] time by rearranging requests.

Drag options to blanks, or click blank then click option'

Aseek

Btransfer

Cwaiting

Dprocessing

Attempts:

💡 Hint

Common Mistakes

Choosing seek time because it is related to movement.

Choosing transfer time which is about data movement, not scheduling.

The sentence is incorrect because disk scheduling reduces waiting time, not increases it. The correct term to fix the sentence is waiting time.

4fill in blank

hard

Fill both blanks to complete the explanation of disk scheduling.

Operating Systems

Disk scheduling [1] the sequence of requests to reduce [2] time.

Drag options to blanks, or click blank then click option'

Bincreases

Cseek

Dtransfer

💡 Hint

Common Mistakes

Choosing 'increases' which is opposite of the goal.

Confusing seek time with transfer time.

Disk scheduling reorders the sequence of requests to reduce seek time, which helps the disk head move less and faster.

5fill in blank

hard

Fill all three blanks to explain how disk scheduling improves performance.

Operating Systems

By [1] requests based on their [2], disk scheduling [3] the total seek time.

Drag options to blanks, or click blank then click option'

Aordering

Blocation

Dignoring

Attempts:

💡 Hint

Common Mistakes

Choosing 'ignoring' which would not help performance.

Mixing up ordering and ignoring.

Disk scheduling improves performance by ordering requests based on their location on the disk, which reduces the total seek time needed for the disk head to move.
