If, however, the data needs to be kept in some form, then it must be copied from the stack to the heap before the function exits. Therefore, stack based allocation is suitable for temporary data or data which is no longer required after the current function exits. A thread's assigned stack size can be as small as only a few bytes on some small ...
The set of values pushed for one function call is termed a "stack frame". A stack frame consists at minimum of a return address. Automatic variables are also allocated on the stack. The stack segment traditionally adjoined the heap segment and they grew towards each other; when the stack pointer met the heap pointer, free memory was exhausted.
This shows the typical layout of a simple computer's program memory with the text, various data, and stack and heap sections. In computing, a code segment, also known as a text segment or simply as text, is a portion of an object file or the corresponding section of the program's virtual address space that contains executable instructions.

In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a heap.
Example of a binary max-heap with node keys being integers between 1 and 100. In computer science, a heap is a tree-based data structure that satisfies the heap property: In a max heap, for any given node C, if P is the parent node of C, then the key (the value) of P is greater than or equal to the key of C.
A heap overflow, heap overrun, or heap smashing is a type of buffer overflow that occurs in the heap data area. Heap overflows are exploitable in a different manner to that of stack-based overflows. Memory on the heap is dynamically allocated at runtime and typically contains program data.
Heap (data structure), a data structure commonly used to implement a priority queue; Heap (mathematics), a generalization of a group; Heap (programming) (or free store), an area of memory for dynamic memory allocation; Heapsort, a comparison-based sorting algorithm; Heap overflow, a type of buffer overflow that occurs in the heap data area
Stack-oriented programming is a programming paradigm that relies on one or more stacks to manipulate data and/or pass parameters. Programming constructs in other programming languages need to be modified for use in a stack-oriented system. [ 1 ]
