-  In Emacs editing, a @dfn{frame} is a screen object that contains one
-or more Emacs windows, see @ref{Windows}.  It's the kind of object that
-is called a ``window'' in the terminology of graphical environments; but
-we can't call it a ``window'' here, because Emacs uses that word in a

   A frame initially contains a single main window and/or a minibuffer
 window; you can subdivide the main window vertically or horizontally
 into smaller windows.  @xref{Splitting Windows}.
 
+@cindex terminal
   A @dfn{terminal} is a display device capable of displaying one or
-more Emacs frames.  On GNU and Unix systems, Emacs supports any number
-of different terminals in one session, and can mix GUI and text-only

+more Emacs frames.  In Emacs Lisp, a @dfn{terminal object} is a Lisp
+object that represents a terminal.  @xref{Terminal Type}.
 
 @cindex terminal frame
-  When Emacs runs on a text-only terminal, it starts with one
-@dfn{terminal frame}.  If you create additional frames on the same
-terminal, Emacs displays one and only one at any given time---on that
-terminal screen, of course.  You can create additional frames, either
-text-only or GUI, on other terminals from the same Emacs session.
-(This comes in handy when you connect to the same session from several
-remote locations.)  @xref{Multiple Terminals}.
-
 @cindex window frame
-  When Emacs communicates directly with a supported window system, such
-as X, it does not have a terminal frame; instead, it starts with
-a single @dfn{window frame}, but you can create more, and Emacs can
-display several such frames at once as is usual for window systems.
+  There are two classes of terminals: text-only terminals and
+graphical terminals.  Text-only terminals are non-graphics-capable
+display devices, including ``terminal emulators'' such as xterm.  On
+text-only terminals, each frame occupies the entire terminal screen;
+although you can create additional frames and switch between them,
+only one frame can be shown at any given time.  We refer to frames on
+text-only terminals as @dfn{terminal frames}.  Graphical terminals, on
+the other hand, are graphics-capable windowing systems, such as the X
+Window System.  On a graphical terminal, Emacs can display multiple
+frames simultaneously.  We refer to such frames as @dfn{window
+frames}.
+
+  On GNU and Unix systems, you can create additional frames on any
+available terminal, within a single Emacs session, regardless of
+whether Emacs was started on a text-only or graphical terminal.  Emacs
+can display on both graphical and text-only terminals simultaneously.
+This comes in handy, for instance, when you connect to the same
+session from several remote locations.  @xref{Multiple Terminals}.
