The A330's body and wings are nearly exactly the same as the smaller versions of the A340's wings and body, but they have different engines. The A330's body is also similar to the older Airbus A300, and the computers and systems (like the fly-by-wire system) are similar to the Airbus A320 family of aeroplanes. Also, both the A330 and A340 are built at the same place: Toulouse-Blagnac Airport in Toulouse in France.
