- Consider a system with four identical resources that are shared by three processes, with the maximum number of resources required by any one process being two. Show that there are no deadlocks in the system.Suppose there are five processes, their arrival time and running time are listed as follows. Adopt FCFS and SJF, respectively, give the schedule order and average waiting time. Give the schedule order of SJF. Compute the average waiting time of SJF. Process Arrival time Running time P1 P2 P3 P4 0 3 4 5 3 10 6 1A deadlock occurs when a group of processes is stalled because one process is holding a resource and waiting for another process to obtain it. Consider the situation when two trains are approaching each other on the same track and there is only one track: once they are in front of each other, neither train can proceed. In operating systems, a similar scenario happens when two or more processes possess certain resources while waiting on resources owned by other processes (s). In the picture below, Process 1 is holding Resource 1 and waiting for Process 2 to acquire Resource 2, while Process 2 is waiting for Resource 1. Give an example of a realistic deadlock avoidance approach and describe the basic strategy behind it.
- Consider a system consisting of m resources of the same type being shared by n processes, n > m. Each process has a maximum need of m/2 resources. Initially, each process has no resource requests. A process can request or release only one resource at a time. With n=3k and m=2k, for some integer k, show that the system is deadlock free.Consider a system consisting of 5 processes, P = {P1, P2, P3, P4, P5} and 3 resources types, R = {R1, R2, R3}. The number of instances for each resource type are 2, 2 and 1 respectively. The state of the system at time, it is described as follow: P1 requests an instance of R2 P2 requests an instance of R1 P3 requests an instance of R2 and holds an instance of R1 and an instance of R3 P4 requests an instance of R3 P5 holds all instances of R2 Assuming that all resources are non-sharable, construct a Resource Allocation Graph to depict the process state.assume a system has 6 identical resources and N processes competing for them. each process can request at most 2 resources. what is the maximum value of N for the system to be deadlock free?
- Consider a system with five processes and three resource type. Resource type X has 7 instances, resource type Y has 10 instances and resource type Z has 5 instances. Suppose that at time 0, the following snapshot of the system has been taken. Is the process safe? If yes, what is the safe sequence? If not, which process is unsafe?Let the processes P1, P2, P3, P4, and P5 be given. They arrive in the system at the same time in this order. The processes have the attached file as service times (in time units) and priorities. For each of the scheduling methods (First Come, first served (FIFO), Shortest Job First, Round Robin, and Priority Scheduling), specify the execution order of the processes and the average execution time (average turnaround time) for all processes. First, determine and state the execution times of the individual processes and then calculate the average value. Note: • For Shortest Job First, If the required service time (CPU time) is the same for two or more processes, use First Come, first served to resolve the conflict. • For Round Robin, the time quantum q = one time unit. • For Priority Scheduling, low integer priority values signify high priorities, with O being the highest possible priority. If multiple processes have the same priority, use First Come, first served to resolve the conflict.…Let the processes P1, P2, P3, P4, and P5 be given.

- Given is the scenario for the three processes p0,p1 and P2. You need to find out whether deadlock has detected or not? (If yes, then explain in the sheet which processes can't be executed and if no, what is the safe sequence and how?) In option, you are supposed to mention yes and no for deadlock detection. (A) Yes, deadlock is detected (B) No, deadlock is not detectedConsider a computer system which has four identical units of a resource R. There are three processes each with a maximum claim of two units of resource R. Processes can request these resources in any way that is, two in one shot or one by one. The system always satisfies a request for a resource if enough resources are available. If the processes don't request any other kind of resource, show that the system never deadlocks?Consider a system with five processes, PO →P4, three resource types, A, B, C. Type A has 9 instances, B has 6 instances, C has 6 instances. At time To the following snapshot of the system is taken.
