ITPEC IP April 2021 Question 23
ITPEC IP April 2021 — Question 23 of 100
Fragmented files may take longer to read because their blocks are scattered across nonconsecutive disk areas. On a hard disk drive, the head must seek among multiple physical locations instead of reading a contiguous sequence, increasing access time. The data remains logically readable and writable.
Answer (d)
Why not others:
- fragmentation does not prevent antivirus detection
- the file system can still write data into available noncontiguous blocks
- it also tracks those blocks so the data can be read correctly
Key rule: Fragmentation primarily degrades access performance; defragmentation reorganizes blocks into more contiguous areas.
