Stacks are described as only allowing the top item to be accessed or modified. Which WRAMP CPU feature(s) prevent a program from accessing other items within the stack?Question 6Select one:a.The CPU compares the requested address to the value stored in the $sp register, and generates a General Protection Fault if they are not equal.b.It is up to the programmer to make sure only valid items are accessed; the CPU does not know or care if a memory address is a valid part of the stack.c.The stack is located in an isolated section of memory, and therefore it is not possible to access invalid items.d.The CPU checks if the requested address corresponds to the top item on the stack; if not, the CPU will generate a General Protection Fault exception.

What happens if a WRAMP program pushes too many items onto the system stack? Assume no boundary checking is performed.Question 10Select one:a.The CPU will throw an out-of-memory exception.b.The push instruction will fail.c.It will eventually overwrite the program's data and instructions.d.Stack overflow exception.

17. What is the role of the top variable in a stack implementation?a. It stores the value to be pushed.b. It tracks the most recently added element.c. It points to the bottom of the stack.d. It manages the display operation.18. What is a potential limitation of array-based stacks?a. Limited by the fixed size of the arrayb. Can lead to stack overflowc. Offers dynamic sizingd. Requires additional memory for pointers19. In the C++ code for pushing elements onto a stack, what is stack[top] = x; doing?a. Removing the top elementb. Initializing the stackc. Adding an element to the stackd. Checking if the stack is full20. In the C++ code for displaying elements in a stack, what does the loop for(i = top; i >= 0; i--)do?a. Adds elements to the stackb. Removes elements from the stackc. Checks if the stack is emptyd. Displays elements in reverse order

Suppose someone designed a Stack data abstraction with the following operations:(a) Push: Adds an element on top of the stack.(b) Pop: Removes the top element from the stack.(c) Top: Returns a pointer to the top of the stack.Give your critical comment on the design of this data abstraction.

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

Which of the following is not an operation on a stack?
