What is the main advantage of the layered approach to system design?

As in all cases of modular design, designing an operating system in a modular way has several benefits. The system is easier to debug and modify because alters affect only limited sections of the system rather than touching all sections of the operating system. Information is kept only where it is required and is accessible only within a explained and restricted area, so any bugs affecting that data must be limited to a particular module or layer.
