A computer system supports 32-bit virtual address as well as 32-bit physical addresses. Since the virtual address space is of same size as that of physical address space, if we want to get rid of virtual memory, which one of the following is true
- A.
Efficient implementation of multiuser support is no longer possible
- B.
The processor cache can be made more efficient
- C.
Hardware support for memory management is not needed
- D.
CPU scheduling can be made more efficient
Attempted by 47 students.
Show answer & explanation
Correct answer: C
When virtual and physical address spaces are identical, removing virtual memory allows processes to access physical addresses directly. Consequently, the Memory Management Unit required for address translation becomes unnecessary, meaning hardware support for memory management is not needed.
