A microkernel is a minimal computer operating system kernel which, in its purest form, provides no operating system services at all, only the mechanisms needed to implement such services, such as low-level address space management, thread management, and inter-process communication (IPC).
What is difference between monolithic kernel and microkernel?
Monolithic kernels are big in size, while microkernels are small in size – they usually fit into the processor’s L1 cache (first generation microkernels). In monolithic kernels, the device drivers reside in the kernel space while in the microkernels the device drivers are user-space.

What are the advantages of microkernel?
One benefit of the microkernel approach is ease of extending the operating system. All new services are added to user space and consequently do not require modification of the kernel. The microkernel also provides more security and reliability, since most services are running as user — rather than kernel — processes.
