Show answerHide answer

Correct answer: (C) It is a chip to map virtual address to physical address

Explanation

Memory management unit (MMU), sometimes called paged memory management unit (PMMU), is a computer hardware unit having all memory references passing through itself, primarily performing the translation of virtual memory addresses to physical addresses. It is usually implemented as part of the central processing unit (CPU), but it also can be in the form of a separate integrated circuit. So we can say it is a chip to map virtual address to physical address
