![]() (b) What is disk scheduling? Explain the C-SCAN scheduling by giving an example. (a) Briefly explain about single-level, two-level and three Structured directories. (b) What are the disadvantages of single contiguous memory allocation? Explain. How many page faults would LRU and FIFO replacement algorithm? There are different techniques for deadlock detection, including the banker’s algorithm, the resource allocation graph algorithm, and the wait-for graph algorithm. (a) What is the purpose of paging the page table? Consider the following page reference string 1,2,3,4,5,1,2,3,4,5 for a memory with three frames. Deadlock detection is an important aspect of operating system design and is crucial for ensuring system stability and reliability in modern computing environments.

(b) Distinguish between client server and peer to peer model of distributed systems. (a) Write are the functions of operating systems? write a note on multi programmed operating systems ? Deadlock avoidance algorithms, on the other hand, use a more dynamic approach to managing resource allocation. The Deadlock prevention techniques include resource ordering, deadlock detection, and avoidance of circular wait conditions. The Deadlock prevention, on the other hand, requires the system to be designed in such a way that deadlocks cannot occur in the first place. Difference between Deadlock Avoidance and Deadlock PreventionÄeadlock avoidance differs from deadlock prevention in that it allows a system to allocate resources dynamically while still preventing deadlocks from occurring. ![]() Deadlock prevention involves designing a system in such a way that deadlocks cannot occur, while deadlock avoidance involves dynamically managing the allocation of resources to prevent deadlocks from occurring. There are two approaches to dealing with deadlocks: prevention and avoidance. Deadlocks can cause a system to become unresponsive and can lead to resource wastage. Deadlock is a situation that occurs in a computer system when two or more processes are unable to proceed because each is waiting for the other to release a resource.
