Which of the following components ensures that process can execute within its own address space?a.Stack pointersb.All of the abovec.I/O Deviced.Memory addressing hardware

The component that ensures a process can execute within its own address space is d. Memory addressing hardware.

Here's why:

a. Stack pointers: These are used to keep track of the top of the stack in memory management. They don't ensure a process executes within its own address space.

b. All of the above: This option can't be correct because stack pointers and I/O devices don't ensure a process executes within its own address space.

c. I/O Device: These are used for communication between the computer and the external world. They don't ensure a process executes within its own address space.

d. Memory addressing hardware: This is the correct answer. Memory addressing hardware includes mechanisms that map the virtual address space a process sees into the physical memory of the computer. This ensures that each process can execute within its own address space.
