Regarding the bss segment and data segment in Unix

Question

Answer 1

bss is traditionally the so-called uninitialized variables, but C and Unix guarantee they are initialized to zero. (See this.) It is a portion of the data segment, usually right after the program-statically-initialized-variable space. Just higher in memory than bss is usually the beginning of the heap.
