A stack frame is memory management to create or destroy the temporary storage area at top of the current stack which is private to subroutine or function. It helps to permit the stack of recursive calling functions or subroutines and it only exists at run time.

Answer:

True

Step-by-step explanation:

A stack frame, also known as an activation record or stack frame record, is a data structure used in memory management during the execution of a program. It represents a specific instance of a subroutine or function call and contains information necessary for its execution. While some of the information mentioned are accurate, there are a few clarifications:

Memory Management: A stack frame is used for memory management, but specifically for managing the local variables and parameters of a subroutine or function. It provides a temporary storage area on the stack where these variables and parameters can be allocated and deallocated as needed during the execution of the subroutine or function.

Creation and Destruction: The stack frame is created when a subroutine or function is called and destroyed when the subroutine or function completes its execution. The creation of a stack frame involves allocating the necessary memory for local variables, parameters, return addresses, and other bookkeeping information. Upon completion, the stack frame is deallocated, and the memory is freed for reuse.

Recursion: One of the key purposes of stack frames is to enable recursion. Recursion occurs when a subroutine or function calls itself. Each recursive call creates a new stack frame on top of the existing stack, allowing the recursive function to maintain separate instances of local variables and parameters for each recursive invocation.

Runtime Existence: Stack frames exist at runtime when a program is executing. They are dynamic and created and destroyed as the program flows through subroutine and function calls.

Overall, a stack frame provides the necessary data structure for managing local variables, parameters, return addresses, and other relevant information during the execution of subroutines or functions. It facilitates memory management, recursion, and the proper execution of program flow.
