Stories can be told from different points of view; the point of view depends on who is telling the story. If the narrator is a character in the story, the pronoun in the text is usually "I". This is called first-person narrator. If the narrator is a voice that seems to to know what just one character is doing, then the point of view is called third-person limited narrator. If the narrator is a voice that knows everything about the story and characters, the point of view is called omniscient, or all-knowing, or all seeing.
To summarize point of view in literature refers to the person telling the story. There are three possible points of view in a novel.
First-person narrator is a character telling the story as he or she experienced it.
Third-person limited narrator knows what one character is doing and thinking.
Third-person omniscient narrator knows what all the characters are doing and thinking.
