i read it from a website ....is it correct:-"A page fault doesnt mean a missing page in the memory. A page can still be present and be dirty. This is also a page fault. On a general note, the page fault refers to the scenario where the obtained translation cannot be effectively used. It may be a missing page or a dirty page or access permission mismatch.";

yes it is correct because accessing page from memory is not just getting entry from TLB and fetching it from TLB but we should be able to fetch correctly  updated (not dirty )   page with  required access control rights
