A process enters a monitor by calling one of its procedures. Only one process may be active in a monitor at any given time. When the "Signal and Continue" approach (Mesa semantics) is applied, the signaling process P is placed on the Urgent Queue. F2 Monitors can be implemented using semaphores.

In Concurrent Development Model, when initial communication is completed modeling makes a transition into a. under development state b. awaiting changes state c. done state d. none stateDescribe the benefits of using dynamic multithreading in a programming environment.Q-5: A semaphore for a resource with four channels is defined by the following structure (after multiple operations running for some time ending with the three waits shown below) Process 100: wait( s1); Process 101: Process 105: wait(s); wait(s1); This produces the current values of the semaphore as: semaphore s1 { } value = -3; *list={100, 101, 105) // processes will be awakened in order from left to right Describe how the semaphore value and list change for the following sequences: What is *list and value? What is list and value? What is *list and value? What is list and value? What is list and value? Process 111: signal(sl); Process 91: signal(s1); Process 110: wait(s); Process 95: signal(sl); Process 113: signal(sl); For this does it make sense that Process 105 can execute a signal function?

- The priority queue is an abstract data type that contains the following methods: insert(item, priority Value) Inserts item into the priority queue with priority value priority.Value. peek() Returns (but does not remove) the item with highest priority in the priority queue. delete() Removes and returns the item with highest priority in the priority queue. changePriority(item, newPriority) Changes the priority of an item to a new priority value. Write down the algorithm and implement a priority queue (both min and max) using a heap tree-based data structure (both min and max). Determine the runtime for each of the following: 1. In the worst case, describe the runtime to insert an item into the priority queue. 2. In the worst case, describe the runtime to remove the element with highest priority. 3. In the worst case, describe the runtime to change the priority of an element. Show an example for each.Round-Robin (RR): Write a Java program to implement a Round-Robin (RR) scheduling algorithm with quantum q that will be entered by user. Your program should first prompts the user to input a list of process ID, arrival time, and burst time (in ms) for each process to be run on the CPU. The list is terminated by 0 0 0 for the process ID, arrival time, and burst time. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the RR scheduling algorithm. Also print the turnaround, response, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.Shortest-Remaining-Time-First (Preemptive SJF): Write a Java program to implement a Shortest-Remaining-Time-First (Preemptive SJF) scheduling algorithm. Your program should first prompts the user to input a list of process ID, arrival time, and burst time (in ms) for each process to be run on the CPU. The list is terminated by 0 0 0 for the process ID, arrival time, and burst time. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the RR scheduling algorithm. Also print the turnaround, response, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.
