1.5 How does the distinction between kernel mode and user mode function as a rudimentary form of protection (security)?
Step by step
Solved in 3 steps
- How does the separation between kernel mode and user mode work as a basic security (or protection) system?What would be the nutshell version of all the jobs done by the various kernel components?How does the distinction between kernel mode and user mode function as a rudimentary form of protection (or security) system?
- 1. Quite a lot of computer systems do not make a provision for a privileged mode of operation in their hardware. Is it conceivable to design a secure operating system for these computer systems? Give arguments for and against. 2. With several definitions of operating systems, there is a contemplation whether operating systems should include applications such as notepad, paint etc. Argue for both assertions and provide supporting arguments. 3. How does the kernel mode and user mode provide such form of security to the operating systems? 4. Imagine you are designing an operating system, what key services would your operating system provide. In each service, provide whether user space programs can provide such services. Explain.Why did the creators of Linux decide to go with a kernel that does not support preemption? In a computer system that only has one CPU, what roles does a kernel that cannot be preempted play? Why does the advantage become less significant with systems that have several processors?What are the advantages and disadvantages of making only some of the symbols defined inside a kernel accessible to a loadable kernel module?
- Why did the original architects of Linux decide to create a kernel that does not support preemptive processing?In a computer system with just one CPU, why would you want to use a non-preemptible kernel? On the other hand, why does having several processors in a system make the benefit less significant?Why did the creators of the first version of Linux decide to create a non-preemptible kernel? What use does a non-preemptible kernel serve in a system with only one processor?

- Why did the developers of the initial version of Linux choose to make the kernel of the operating system non-preemptible?If there is just one CPU in the system, what use does a kernel that is not preemptible serve? Therefore, why does the gain become null and void when using a machine with several processors?Linux creators opted for a non-preemptible kernel from the outset because...Can you explain the benefits of a non-preemptible kernel on a single-processor computer? Why does the benefit decrease as the number of processors used increases?Why did the developers of Linux decide to use a kernel that is not preemptible?With a computer system with just one CPU, what use does a kernel that is not preemptible serve?
