Whenever I read the man page of gcc or other help/books I found the term heap, buffer, stack etc all of these terms are same or different or they are just referring the memory we allocate using malloc or calloc? Looking for simple clarification

Memory
-----------------
c code (bin) --> 1
-----------------
static data --> 2
-----------------


stack --> 3


-----------------
Heap --> 4
-----------------

1) Machine instruction aka your compiled C code
2) Gloable variable, static variables (variables which exists throught program)
3) Dynamically allocated storage (linked list created using malloc())
4) Info about function call in your code

Hope this clears the picture

rockdalinux that is pretty good picture of how program looks when loaded in memory? And to add to that info

A Buttfer is a block of memory that holds "multiple instances of the same data type"

A Heap It is a space a program reserves for a variable. (You access the heap when you use the malloc() function).

So all of them are NOT the same...
