What is the role of dividing memory into stack and heap in resource management of an application?

Memory separation in applications, dividing into stack and heap, plays a crucial role in resource management:

• The stack is used for storing local variables and function calls. It operates on a LIFO (last-in, first-out) principle, which provides fast allocation and deallocation of memory. Memory in the stack is automatically allocated when entering a function and freed upon exit.

• The heap is intended for dynamic memory allocation, for example, for objects whose lifespan exceeds that of a single function. Memory in the heap is allocated and freed manually or with a garbage collector.

This separation allows for efficient resource management: the stack provides quick handling of temporary data, while the heap offers flexibility for objects with a long lifespan. In iOS, for example, Objective-C or Swift objects are usually allocated on the heap, while primitives and references are on the stack.
