A few basics to get you started;
"Zoom" means you can vary the focal length, or you might describe it as magnification (in binocular terms).
A Telephoto lens is one that apparently magnifies a view compared to your naked eye.
A Wide angle lens is one that 'gets more in'.
Both types of lenses can be fixed focal length (also called "prime") or Zoom.
For example;
Fixed Telephoto = 300mm, Zoom Telephoto = 70-300mm.
Fixed Wide angle = 28mm, Zoom Wide Angle = 12-24mm.
Some lenses even cover both and zoom all the way from Wide Angle to Telephoto.
e.g. 18-200mm.
So you see that zoom and telephoto are not mutually exclusive words.
Surely the D40 came with a lens, which one do you have?
Lens compatibility is complex, for now, despite Mark's advice being accurate, best only to look at Nikon AF-S lenses, if you see any others, ask us before placing an order to avoid a possibly expensive mistake.
Cheers,
