How to tell emacs is running under term or windows?

How to tell emacs is running under term or windows?

[Corsair]

Hi everybody!  I have a setting concerning the frame size in my
.emacs:

    (set-frame-size (car (frame-list)) 100 45)

However, when started in a term, emacs will display an error:

    X windows are not in use or not initialized.

So the `set-frame-size' function should be called only when running
under windows system.  The problem is, how to tell that emacs is
running under a term or a windows system, or, to be simple, how to
tell if the `-nw' option is issued when starting emacs?

Thanks.

     window-system is a built-in function in `C source code'.
     (window-system &optional FRAME)

     The name of the window system that FRAME is displaying through.
     The value is a symbol---for instance, 'x' for X windows.
     The value is nil if Emacs is using a text-only terminal.

     FRAME defaults to the currently selected frame.
