Yup, exactly. In general, you have the following memory areas when you
execute a program: (the first three usually come from the executable
file if this has any sense in your environment)

  + text:   contains executable code
  + data:   contains pre-initialized data
  + bss:    same as data, but content is initialized to zero (convenient
            to avoid storing those zeroes in the executable file)
  + heap:   where your global allocations come from
  + stacks: not shared between thread of controls (each one may have
            several stacks) - those stacks may be allocated in the heap
            or may be separate
