What is compaction?
Correct Answer: C
Question 27 Explanation:
→ Compaction refers to combining all the empty spaces together and processes. Compaction helps to solve the problem of fragmentation, but it requires too much of CPU time.
→ It moves all the occupied areas of store to one end and leaves one large free space for incoming jobs, instead of numerous small ones.
→ In compaction, the system also maintains relocation information and it must be performed on each new allocation of job to the memory or completion of job from memory.
