7. Which of the following is NOT a component of the memory hierarchy?

Secondary storage (e.g., hard disk)

In the context of memory allocation, what is an activation record?

A data structure that stores information about a function's execution.

A record that keeps track of memory leaks.

A type of memory block allocated on the heap.

An array that holds the return addresses of all functions in a program.

How can non-local data be accessed on the stack within nested procedures?

By passing pointers to the data as function arguments.

Non-local data cannot be accessed on the stack.

What is a potential issue with nested procedures in terms of memory management?

It can lead to increased memory fragmentation.

Nested procedures are more memory-efficient than non-nested procedures.

Nested procedures always result in memory leaks.

It is not possible to have nested procedures in memory.

How can programmers reduce memory fragmentation in their programs?

By using dynamic allocation exclusively.

By avoiding the use of heap memory.

By using manual deallocation requests.

By allocating and deallocating memory in a balanced manner.

What is manual deallocation in memory management?

Storing memory addresses in a global variable for later use.

Automatically releasing memory when it is no longer needed.

Releasing memory by calling a specific function to deallocate it.

Letting the operating system handle memory deallocation.

2. Static allocation of storage refers to:

Allocating memory at compile-time

3. Dynamic allocation of storage refers to:

Allocating memory at compile-time

5. What is an activation record?

A dynamically allocated variable

A data structure used to store information about a function call

9. Which of the following statements is true about stack-based allocation?

It is suitable for managing dynamically allocated objects

Memory allocation is done at compile-time

Memory allocation is done at run-time

It is suitable for managing global variables

10. The activation tree represents:

The order of function calls during program execution

The order of variable declarations in a program

The order of function definitions in a program

The order of library function calls in a program

18. What is the purpose of the activation record's return address field?

To store the address of the first instruction in the function

To store the value returned by the function

To store the address of the next function call

To store the address of the calling function's return point

22. What is the role of a linker in the run-time environment?

It handles input/output operations

It converts source code into machine code

It resolves external references between program modules

It manages memory allocation during program execution

26. Which of the following is true about global variables in stack-based allocation?

They are accessible from any function.

They have limited scope within a function.

They are allocated at compile-time.

33. What does the term "activation tree" refer to?

A data structure used to manage memory allocation

A data structure used to represent program flow

A data structure used to store global variables

A data structure used to represent function call hierarchy
