9. Facilitates entry and exit.
10. It tends to link devices , it must be in charge of communicating with peripheral devices, when the user so wishes.
11. It must be constituted in a way that condescends development.
12. The software application are programs that are designed to design.
13. They are a set of programs that facilitate the platform environment, and in turn allow its design.
14. The system includes resources that will need to be used by subsequent systems.
15. It works with any other special requirement that the system must respond to.
