Answer 2

Answer:

Option MMU - The memory management unit manages the memory allocation and deallocation.

Explanation:

• In a multiprogramming computer, the operating system occupies a portion of memory, while the remainder is shared among several processes.
• Memory management is the practice of dividing memory across many operations.
• Memory management is an operating system approach for coordinating actions between the main memory and disc during the execution of a task.
• The primary goal of memory management is to maximise memory use.

Memory management is required:

• Before and after the process, allocate and de-allocate memory.
• To keep track of how much memory is being consumed by processes.
• To keep fragmentation to a minimum.
• To make the best use of the main memory.
• To keep data safe while the process is running.

Hence, MMU manages the memory allocation and deallocation.
