Section AAttempt all q u e s t i o n s i n b r i e f . 2 x 10 = 20
- aWhat is the need for a Real-Time Operating System (RTOS) ? 2
- bProvide examples of applications where real-time systems are crucial. 2
- cDiscuss the differences betw een hard real-time and soft real-time systems. 2
- dWhat are the key performance metrics used to evaluate the effe ctiveness of a Real-Time Operating System (RTOS)?
- eDefine interrupt routines and their role in handling hardware and software events in an RTOS
- fExplain the concept of task priority and how it influences tas k scheduling and execution
- gDiscuss the key differences between real-time databases and ge neral-purpose databases
- hDiscuss 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
- aCompare and contrast the features of General-Purpose Operati ng Systems (GPOS) and Real-Time Operating Systems (RTOS)

- aDiscuss the advantages and disadvantages of each concurrency control approach in real-time databases
- bProvide an overview of disk sc heduling algorithms used in re al-time databases
- aExplain the strategies and m echanisms used to contain faults and prevent them from spreading to other parts of the system
- bExplain how time redundancy techniques, such as retry mechan isms and time-based voting, are used to address transient faults
