what is lectern
A lectern is a flat, raised surface upon which to lay speaking notes. They are available in tabletop and standalone models. A speaker stands behind a lectern. A podium is a platform upon which a speaker stands while speaking. If that sounds like a stage, you are correct. It IS like a stage. A podium can have a lectern on it, so can a stage. You could have a lectern on a podium on a stage. A speaker stands on a podium. This difference doesn't matter a whole lot until you need to work with a meeting planner, hotel, or audio/visual supplier. You want to get it right and ensure they also get it right.
