Test a system without system calls. Do mature operating systems need additional system calls?

Any design guidelines for the operating system's microkernel are available. To what extent does this method vary from the modular approach?

How do the benefits of operating system abstraction present themselves, and which are the most important?

In the process of designing the microkernel of an operating system, what should serve as the guiding principle? Is there any significant difference between it and the modular approach in terms of the tasks that it performs?

Does the microkernel of the operating system follow any specific design principles? Is this approach comparable to or distinct from a more conventional modular strategy?

Is it not useful to quickly examine the two components of an operating system that are generally recognised as being essential in this context?

Is there a fundamental principle that the design of the microkernel in an operating system adheres to? Is there any distinction between this methodology and the modular approach?

Does the microkernel of the operating system adhere to any design principles? What is the most significant distinction between this method and the modular strategy?

Which approach to design should be used as a foundation for the creation of a microkernel for an operating system? Why is it successful while the modular approach is unsuccessful?
