A third-person point of view can be omniscient, in which the narrator knows all of the thoughts and feelings of all of the characters in the story, or it can be limited. If it's limited, the narrator only relates his or her own thoughts, feelings, and knowledge of various situations and other characters. for example, Sara felt upset that Mary was mad how could she have known the cake would burn? that was third person omniscient. Mary screamed how ignorant can you be!? of course the cake would burn if you left it for too long! this is third person limited. notice how in the second one it is more limited hence the term third person limited.
