The kernel is very modular and has a well defined interface between it and device-drivers and file-systems. All components communicate through a thin, well defined interface, and know little about each other, as in a micro-kernel. But, all kernel components live in kernel-space and are unprotected from each other, as in a monolithic-kernel.
