    Question

    What is the primary purpose of the memory management process known as "compaction"?

    A To increase the speed of memory access by reorganizing data for faster retrieval. Correct Answer Incorrect Answer
    B To merge fragmented free memory spaces into a larger contiguous block to efficiently allocate memory for processes. Correct Answer Incorrect Answer
    C To create multiple copies of the memory space to ensure redundancy and reliability in case of failure. Correct Answer Incorrect Answer
    D To encrypt memory contents to enhance data security and prevent unauthorized access. Correct Answer Incorrect Answer
    E To divide large memory chunks into smaller segments for more efficient use and better performance. Correct Answer Incorrect Answer

    Solution

    Memory compaction is a process used in memory management to address fragmentation by consolidating free memory spaces into a single, larger contiguous block. Over time, as processes are loaded and unloaded, memory can become fragmented with small free spaces scattered throughout. Compaction reorganizes the memory, moving allocated blocks together and combining the free spaces into a larger chunk. This process helps in efficiently allocating memory to new processes and reduces the likelihood of fragmentation, which can lead to inefficient use of memory and allocation failures. The main goal is to ensure that sufficient contiguous memory is available for processes that require large blocks of memory.
