Q4 a) b) Q5 a) b) Q6 a) b) Q7 a) b) Q8 a) b) c) d) What do you mean by priority inversion? Distinguish bounded from unbounded priority inversion. Demonstrate with a neat diagram. Briefly explain the highest locker protocol scheme for avoiding priority inversion. (5) How dynamic allocation of real time task can be made in a microprocessor? Explain with an example. Define Notion of clock and clock synchronization in context of real time systems. Explain non fault tolerance synchronization algorithm. (5) Why traditional UNIX kernel is not suitable to be used in a multiprocessor environment? Explain how Unix dynamically recomputes task priority values. Define real time communication. Explain virtual time carrier sensed multiple access protocol with a suitable example. (5) Evaluate the suitability of Windows-NT as a Real-time OS. Why is dynamically changing the priority levels of tasks important for traditional operating systems? How does this property affect real-time systems? (5) (5) Write short answer on any TWO: UNIX as a RTOS QoS parameters for real-time communication Fail safe state N-version Programming (5) (5) (5) (5 x 2)
