Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Disk defragmentation makes files that are contiguous in a disk as fragmented.
Statement II:A device controller that controls a device will deal with the operating system through a device driver.
ABoth Statement I and Statement II are correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct ✓ Correct
Correct answer: (D) Statement I is incorrect but Statement II is correct
Explanation
Statement 1 is false because disk defragmentation does the reverse, gathering scattered file fragments into contiguous blocks.
Statement 2 is true because a device controller communicates with the operating system through its matching device driver.
Defragmenting reduces read head movement and speeds up access to files.
The driver is the software layer that translates operating system requests into controller commands.
Solid state drives are not defragmented since they have no moving heads.
Each hardware device typically needs its own driver to function.
