If you are referring to the "point of view" (POV) in a book, it's similar.
A book written in lst person would be written from a narrator's point of view, using such phrases as "I am sitting in a room . . . " and the rest of the book would only be from that person's view point.
2nd person is very seldom used. It would be something like "You are sitting in a room . . . ". Very awkward to use.

1st person is the speaker...like you are talking using the word like "i"
2nd person is you talking to someone else...using the words for an example like "you"
3rd is you talking about someone else...using the words like "she/he"
