- How does the separation between kernel mode and user mode work as a basic security (or protection) system?How are these elements put together in order to build a secure enviorment for code execution? Harware-related: - computers are multiprogrammed - There are at least two processors modes: user-mode and kernel-mode - There is a MMU: Memory Management Unite - Interrupts have higher priority than processes Software-related: - There is and operating system - OS - sitting in-between the hardware and applications - The OS offers a collection of system calls, SYSCALLS - Processes compete for protected resources, whilst threads share internal resources by default Processes can be preempted at any moment and they must obey the READY-EXECUTE-WAIT life-cycle.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 does the advantage become less significant with systems that have several processors?What is the difference between a monolithic kernel and a microkernel?Why did the original developers of Linux chose a kernel that did not support preemptive multitasking?What are the advantages of using a non-preemptible kernel in a system that only has one processor? However, why is the value diminished when using a machine with several processors?
- 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 original developers of Linux chose a kernel that did not support preemptive multitasking?What are the advantages of using a non-preemptible kernel in a system that only has one processor?

Why does the benefit decrease as the number of processors used increases?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?
