You can distill an interface from a concrete class once you have the full insights into a problem. The intended interface is just one 'extract interface' refactoring away. ...}}</ref> Operativni sistem može posredovati u komunikaciji između korisnika i hardverskih komponenti ili programi (aplikacije) koji se pokreću pod određenim operativnim sistemom mogu zahtevati komunikaciju sa drugim programima, nitima istog programa ({{Jez-engl-lat|threads}}) ili komunikaciju sa delovima samog operativnog sistema.
