Process Scheduling: Select all statements below that are true Dynamic Priority Round Robin (DPRR) makes use of a preliminary stage containing prioritized queues. When Multilevel feedback (MLF) scheduling is applied, processes at lower priority levels can take more processor time than processes at higher levels. Multilevel Priority (ML) scheduling is based on priority queues and uses a fixed set of priorities. When Multilevel Feedback (MLF) scheduling is applied, processes do not remain at the same priority level, but gradually migrate to lower levels each time they use up their allotted time threshold. Priority Inversion means that low-priority processes can be delayed or blocked by higher-priority processes.
For deadlock to occur, A There must be mutual exclusion in resource allocation to processes There must be hold and wait of resources by processes C There must be circular waiting D All of the above.

Deadlock detection and recovery: Select all of the following statements that are true. A wait-for graph can be constructed from a resource allocation graph by eliminating the resources and collapsing the associated edges. A forced termination of one process to recover from a deadlock never has any side effects on other processes running in the system. In order for a process to be able to return to a previous state, at least one checkpoint of a safe process state is needed. Deadlock detection must be carried out after every resource allocation which cannot be immediately granted. At the start of the banker's algorithm, "Work" refers to the actually available system resources. One sign of a deadlock is that many processes are waiting, although the CPU is not busy.
Please send me answer of this question immediately and i will give you like sure sir
Deadlocks select which is true options: a If a resource-allocation graph is expedient, a knot is a sufficient condition for deadlock. b A deadlock means that at least two processes cannot continue working because they are waiting for each other to terminate or relinquish resources. c The circular wait is one of the four conditions necessary for a deadlock to occur. d Deadlock prevention aims to abort processes or preempt some resources when deadlocks are detected. e The banker's algorithm aims to reduce the Maximum Claim Graph (MCG) completely.

Draw a model in BPMN that can produce every possible execution sequence that includes tasks {p, q, r,s, t}. Discuss the fitness and precision of this model with respect to the workflow log {<p, q, r, s, t>,<p, r, q, s, t>}. Draw a process model that would have perfect fitness and perfect precision with respectto this workflow log. Would the alpha-Algorithm produce this model with perfect fitness and precision?

Suppose a system has 5 processes, P = {P1, P2, P3, P4, P5}, and 4 resources, R = {R1, R2, R3, R4}, where there are 2 instances of R1, 1 instance of R2, 3 instances of R3, and 3 instances of R4. The current state of the system is defined by the following requests and assignments: P1 is requesting an instance of R3 and has been assigned an instance of R2; P2 is requesting an instance of R1 and has been assigned an instance of R3; P3 is requesting an instance of R4 and has been assigned an instance of R1 and an instance of R3; P4 is requesting an instance of R3; P5 is requesting an instance of R2 and has been assigned an instance of R4. Is there deadlock in this system? (Explicitly state yes, there’s deadlock or no, there isn’t.) If applicable, draw a wait-for graph or resource-allocation graph, and use the appropriate graph to justify your answer. If you conclude there is no deadlock, your justification should contain a sequence of execution for the processes which shows that…
Schedulers: Select all of the following statements that are true. A long-term scheduler selects which process should be executed next and allocates the CPU. The main task of a medium-term scheduler is to swap out and in processes from memory. A long-term scheduler executes much more often than a short-term scheduler. The long-term scheduler controls the degree of multiprogramming. The ready queue contains the set of all processes residing in main memory, ready and waiting to execute. Device queues refer to processes waiting for an I/O device.
A Pregel worker: a) Contacts the master for a set of vertices that have not yet been processed in a given superstep and calls the Compute() method on each vertex. b) Is responsible for a single vertex of a graph, calling the Compute() method on that vertex if it is active. c) Is allocated a single partition and runs a thread for each vertex of a graph that loops calling a Compute() method as long as the vertex is active. d) Runs a thread for each partition of a graph, with each thread calling a Compute() method as it iterates through each active vertex.
