The point of view in literature is the angle from which the story is being narrated. The most common are the first and third person points of view.
If it's being told from the first person point of view (POV), then the pronouns "I" or "we" will be used to tell the story. If it's from the third person POV, the story will use the pronouns "he", "she", "it", "them", or the main character's name. And finally, the second person POV narrates with the pronoun "you", inserting the reader in the story.
In the case of Steve Jobs: The Man Who Thought Different, the author Karen Blumenthal tells his biography by using his name and "he" pronouns. For example, the opening sentence says "<em>Steve Jobs's first story involved connecting dots, and it began with a most unusual promise</em>". Therefore, the point of view used to tell this story is the third person.
