Can you indicate the location of stack structures in the system?

Stack structures in a system are usually located in the memory area allocated for the call stack. In operating systems, the stack is placed in the process memory, most often in the stack segment, which is allocated when the program starts.

A separate stack is allocated for each thread in a process, which stores local variables, return addresses from functions, and call parameters.

In 32-bit systems, the stack is usually located at the top of the address space and grows downward (addresses decrease). In 64-bit systems, the principle is similar, but sizes and addresses may differ.

Thus, the stack is a memory area managed by the system and the processor, used for organizing function calls and storing temporary data.
