in microkernel approach device drivers are placed out of the kernel in the user space

1) crashing of the device driver wouldn't lead to crash of the OS.
2) because of above it's more secure than monolithic kernel that's why used in defense application.
3) e.g of microkernel approach is True64,hurd and minix
4)but it's slower than normal approach that follow in windows and Linux.

Micro kernel approach is a step towards modularizing the operating system where all nonessential components from the kernel are removed and implemented as system and user level program, making the kernel smaller. The benefits of the micro kernel approach include the ease of extending the operating system. All new services are added to the user space and consequently do not require modification of the kernel. And as kernel is smaller it is easier to upgrade it. Also this approach provides more security and reliability since most services are running as user processes rather than kernel’s keeping the kernel intact.
