fragments in android

I created a class which is a extends dialog fragment. which is 

public class AlertDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("Oops sorry!").setMessage("There was an error. Please try again").setPositiveButton("OK",null);
        AlertDialog dialog = builder.create();
        return dialog;
    }

}

The main activity uses the fragmet in the following code.

private void alertUser() {
        AlertDialogFragment dialog = new AlertDialogFragment();
        dialog.show(getFragmentManager(),"Error_dialog");

    }

How does the type of dialog in main activity match with the type of dialog that is being returned from the AlertDialogFragment??

How does getFragmentManager() work? What does it return??
