When I asked Google what's the difference between preface and prologue it said this. Is it right?

"Best Answer: In fiction a prologue is written in the same voice as the rest of the book and usually concerns events that occurred before the beginning of the story itself. A preface is written in the author's voice, speaking directly to the reader in order to offer information or context for the story that follows."


Also Can anyone explain the other terms such as epilogue and any of the others like Google did this?
