Which of the following architectural features of modern operating systems is designed to improve multitasking and CPU utilization, and how does it achieve this?Group of answer choices• (b) Layered architecture, which isolates different system functions into separate layers, thus improving modularity and simplifying debugging and maintenance.• (d) Multilevel Feedback Queue Scheduling dynamically adjusts the priority of processes based on their behavior and requirements, allowing for efficient multitasking and improved CPU utilization by prioritizing I/O-bound processes over CPU-bound ones.• (e) Real-time operating system architecture, which ensures deterministic response times for critical applications, thereby enhancing overall system reliability.• (a) Monolithic kernel architecture, which integrates all operating system services into a single large block of code, ensuring faster execution of system calls.• (c) Microkernel architecture, which minimizes the amount of code running in kernel mode, reducing system complexity and enhancing security and stability.

What is the main objective of real-time operating systems?

Which of the following scheduling algorithms is most suitable for real-time operating systems and why, considering factors such as response time and predictability?Group of answer choicesFirst-Come, First-Served (FCFS) scheduling is most suitable for real-time operating systems because it ensures that tasks are executed in the order they arrive, providing simplicity and fairness.Shortest Job Next (SJN) scheduling is most suitable for real-time operating systems as it minimizes the average waiting time by prioritizing shorter tasks, enhancing overall system throughput.Multilevel Queue Scheduling is most suitable for real-time operating systems because it classifies tasks into different priority levels, allowing for flexible task management and improved response times.Round-Robin (RR) scheduling is most suitable for real-time operating systems because it distributes CPU time evenly among all tasks, ensuring no task is starved of resourcesRate Monotonic Scheduling (RMS) is most suitable for real-time operating systems as it assigns fixed priorities to tasks based on their periodicity, ensuring predictable response times. This predictability makes it ideal for systems where meeting timing constraints is critical.
