What are the main advantages of the microkernel approach?

The main advantages are that new services do not need to modify the kernel and it's easier to port between hardware. Also, microkernels provide more security because of less time in privileged mode.

Q Explain the difference between microkernel and macrokernel Give an example of microkernel?

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

What are the key differences between a monolithic kernel and a microkernel in terms of their architecture and performance?

A monolithic kernel has all operating system services running in the same address space, while a microkernel keeps only essential services in the kernel space and runs other services in user space. This makes microkernels more modular and easier to maintain, but can lead to slightly lower performance due to increased communication overhead between components.

What are the disadvantages of a microkernel?

suffer from performance decreases due to increased system function overhead. Consider the history of Windows NT. The first release had a layered microkernel organization. However, this version delivered low performance compared with that of Windows 95. Windows NT 4.0 partially redressed the performance problem by moving layers from user space to kernel space and integrating them more closely. By the time Windows XP was designed, its architecture was more monolithic than microkernel.
