- 50. Match the following.i) Mutual exclusion a) A process may hold allocated resources while waiting assignment.ii) Hold and wait b) No resource can be forcibly removed from a process holding it.iii) No preemption c) Only one process may use a resource at a time. a. i-a, ii-b, iii-c b. i-a, ii-c, iii-b c. i-b, ii-c, iii-a d. i-c, ii-a, iii-b121. Which is refers to a stalemate situation due to which no further progress is possible as computer await response of each other: a. Concurrency b. Deadlock c. Backup d. Recovery97. Every time a request for allocation cannot be granted immediately, the detection algorithm is invoked. This will help identify : a. the set of processes that have been deadlocked b. the set of processes in the deadlock queue c. the specific process that caused the deadlock d. all of the mentioned
- 101. A deadlock can be broken by : a. abort one or more processes to break the circular wait b. abort all the process in the system c. preempt all resources from all processes d. none of the mentionedThere are 3 resources R1, R2 and R3 with one instance each and three processes P1, P2 and P3 in an operating system. A snapshot of the system resource allocation graph shows the following: R1 is allocated to P2; R2 is allocated to P1; R3 is allocated to P3; P1 requests R1; P2 requests R3; P3 requests R2. Which of the following is true about this system? answer ) a)Undetermined b)There is deadlock in the system c)Deadlock will never happen d)There is no deadlock in the systemWrite a JAVA program to simulate the following file organization techniquesa) Single level directory b) Two level directory c) Hierarchica Write a JAVA program to simulate Bankers algorithm for the purpose of deadlock avoidance. *Write a JAVA program to simulate disk scheduling algorithmsa) FCFS b) SCAN c) C-SCAN Write a JAVA program to simulate page replacement algorithmsa) FIFO b) LRU c) LFU
- 43. From the following statements which one is not a valid deadlock prevention scheme? a. Number the resources uniquely and never request a lower numbered resource than the last one b. Release all the resources before requesting for a new resource c. Request all the resources before execution d. Never request a resource after releasing any resourcesWhat describes how the principle of least privlege applies to the use of computers? A, It guarantees that no information inifially held in an object can be used outside its execution environment B, A process is allowed access only to the resources il needs to complete Its task and limit damage from a faulty process C, It is a process that can access an object in a domain only if that domain has a key that malches one of the locks of the object D It is the use of access controls to monitor and limit access to applications, programs, and websites during specific times of use.Those who have come to a standstill due to the detection of deadlocks in their processes are permitted to make resource requests.
- 5. A state is safe if the system can allocate resources to each process (up to its maximum) in some order and still avoid deadlock. Then a. deadlocked state is unsafe b. unsafe state may lead to a deadlock situation c. deadlocked state is a subset of unsafe state d. all of theseWhen a deadlock has been identified, the requested resources are made available to those who are unable to go forward.1. Write a LINUX C code for Banker’s Algorithm to deadlock avoidance.Note: Consider a system with five processes (P0–P4) and three resources (A, B, C). There are 9 instances of resource type A, 4 instances of resource type B, and 6 instances of resource type C
