difference between Dialog and DialogFragment in android?

Question

Upon reviewing the docs in android I've noticed the classes: Dialog and DialogFragment(standard, v4). The Tutorials seem to use the terms interchangeably, thus i'm confused as hell about their differences.

Tell me if i'm right with my understanding: a DialogFragment, is in essence, a wrapper that handle life-cycle events, while returning an Object of Type Dialog, which is the actual UI Object?

Dialog and DialogFragment aren't part of the support v7 – Olympias

Possible duplicate of Android DialogFragment vs Dialog – Olympias

in v7 there are AppCompatDialog, and AppCompatDialogFragment @Olympias – Nudicaul

@Olympias i've read that thread. it didn't explain what i was looking for, otherwise i wouldn't have made this post – Nudicaul

according to the docs the AppCompatDialog and AppCompatDialogFragment use AppCompat themes. not sure if there is any other difference – Olympias
