Explain the difference between microkernel and macro kernel?

Micro-Kernel: A micro-kernel is a minimal operating system that performs only the essential functions of an operating system. All other operating system functions are performed by system processes. Monolithic: A monolithic operating system is one where all operating system code is in a single executable image and all operating system code runs in system mode.

A monolithic kernel has all OS services running within the privileged mode of processor.It has only one address space i.e. kernel space.
A micro-kernel uses the CPUs privileged mode only for really core sevices (task scheduling, interprocess communication and memory allocation). Its has seperate address spaces( kernel space and user space)
