Section AAttempt all q u e s t i o n s i n b r i e f . 2 x 10 = 20
  • a
    What is the need for a Real-Time Operating System (RTOS) ? 2
  • b
    Provide examples of applications where real-time systems are crucial. 2
  • c
    Discuss the differences betw een hard real-time and soft real-time systems. 2
  • d
    What are the key performance metrics used to evaluate the effe ctiveness of a Real-Time Operating System (RTOS)?
  • e
    Define interrupt routines and their role in handling hardware and software events in an RTOS
  • f
    Explain the concept of task priority and how it influences tas k scheduling and execution
  • g
    Discuss the key differences between real-time databases and ge neral-purpose databases
  • h
    Discuss the advantages and challenges associated with storing and managing data primarily in main memory. i. Discuss the importance of understanding failure causes in the context of fault tolerance. j. Write various fault detection m ethods employed in fault tolerance. 2
Section BAttempt any three o f t h e f o l l o w i n g : 10 x 3= 30
  • a
    Compare and contrast the features of General-Purpose Operati ng Systems (GPOS) and Real-Time Operating Systems (RTOS)
  • b
    Explain the concept of a cycli c executive scheduling algorithm. 10
  • c
    Explain the role of messages, queues, mailboxes, and pipes i n a Real-Time Operating System. How do these features facilitate communicatio n between tasks?
  • d
    How are transaction prioritie s assigned, and how do they inf luence the scheduling and execution of transactions in RTOS?
  • e
    Define different types of faults, including hardware faults, software faults, and transient faults
Section CAttempt any one p a r t o f t h e f o l l o w i n g : 10 x 1= 10
  • a
    Explain how factors such as task scheduling, interrupt handl ing, and resource management can impact the real-time performance of an RTOS
  • b
    Provide an overview of the L INUX/UNIX operating system. 10
  • a
    Discuss scenarios where Rate Monotonic Scheduling is suitabl e and its impact on system performance
  • b
    How does Least Laxity Scheduling prioritize tasks based on t heir laxity, and what advantages does this approach offer?
  • a
    Explain the trade-offs involved in RTOS design decisions and their impact on system performance
  • b
    Explain how timers are used t o enforce timing constraints and deadlines. 10
  • a
    Discuss the advantages and disadvantages of each concurrency control approach in real-time databases
  • b
    Provide an overview of disk sc heduling algorithms used in re al-time databases
  • a
    Explain the strategies and m echanisms used to contain faults and prevent them from spreading to other parts of the system
  • b
    Explain how time redundancy techniques, such as retry mechan isms and time-based voting, are used to address transient faults
