If we are talking US Officials, an impeachment is a statement of charges (by the House of Representative) much like an indictment. If a simple majority votes "yes", the person is impeached. The official, however, must be convicted (by the Senate) before being formally removed from office. Often, impeachment is enough to make the person resign. However, not always. Bill Clinton was impeached, stayed in office and the Senate acquitted him.
