A moderator can "lock" a post where it can no longer be edited, voted or commented upon, closed or re-opened. If a question is locked (except for historical significance), no new answers can be submitted, and any of the (unlocked) answers can still be edited (but no suggested edits can be submitted) and voted upon. See What is a "locked" post?. Questions locked for historical significance have all of their answers locked, the vote arrows removed altogether, and the option to flag removed, and (on main sites) do not ordinarily show up in search results.
