Monolithic kernel vs. Microkernel
... Exstensibility is the most prominent fact for µ-kernels. It is, beside its size, one of the biggest difference to monolithic kernels. Adding new features to a monolithic system means recompilation of the whole kernel, often including the whole driver infrastructure. If you have a new memeory managm ...
