Page Faults Defined



please excuse the cross-post, i am trying to reach everyone ;^>

i am repeatedly seeing the term "page fault" being used in Debian in
the wrong way. A page fault, despite its name, has nothing to do with
memory corruption or an invalid access. A page fault simply occurs
when a memory access causes the memory management system to have to
fetch the requested page from swap. invalid accesses to memory, like
dereferencing null pointers or writing beyond the end of protected
storage cause segmentation faults or bus errors.

hope this clears it up.
