The C program has been consisting of the following parts:
1) Text section - CPU execution machine; one program has only one copy; read-only, preventing procedures to modify its own instructions due to accidents; 2) Initialization data segment (data segment) - all assigned in the program The global variable of the value is stored here. 3) Non-initialization data segment (BSS segment) - There is no global variable in the program; the kernel initials this segment into 0.4) stack-growth direction: from top-down, automatic variable and each function call The information you need to save (return the address; environmental information). 5) Heap - Dynamic storage.
