- Write a program for implementing the First Come First Serve (FCFS) scheduling and calculate the average waiting time.In this project, you'll implement one of the following CPU scheduling algorithms by writing a CPU simulator. Shortest Job First (SJF)(Non-preemptive)The shortest job first algorithm is a priority based scheduling algorithm that associates with each process the length of the process's next CPU burst. When CPU is available, it is assigned to the process that has the smallest next CPU burst. Shortest Remaining Time Next (SRTN)(Preemptive)The shortest remaining process next scheduling algorithm is the preemptive Shortest Job First algorithm. With this scheduling algorithm, the process in the ready queue with the shortest execution time is chosen to execute. If a "new process" arrives in the ready queue with a CPU service time less than the remaining time of the current process, preempt. First Come First Serve (FCFS) (recommended)The first come first serve algorithm is simplest CPU-scheduling algorithm. In this algorithm, the process at the head of the queue is allowed to execute until it…What exactly does the term "preemptive scheduling" entail?

Write a program to implement FIFO page replacement algorithm Instruction for lab work: + Students will be allocated any one / choose anyone question to answer. + Kindly use suitable Kali Linux tools to solve these assignment problems. + You have to write the step-by-step commands to solve each problem as well as screenshots at each step. Students can work in teams + Viva will be conducted by course teachers. Students will have to share their screen with the course teacher and practically demonstrate the lab work as per the report submitted. Submit assignment on or before the deadline on Blackboard portal. Late assignment submission will not be allowed. Students should not copy and paste assignments directly from other students. Assignments will also be evaluated based on plagiarism and marks will be deducted if plagiarism found.Write a program for implementing Round Robin (RR) scheduling and calculate the average waiting time. .in C++ please create a Priority : -pre-emptive algorithm code: here are information that will help you Tasks: • Lab 4: Process management • Review Process management algorithms Definitions: (in terms for this lab not formal definitions) • Preemptive: When a new process arrives and has a higher priority than the current running process, Then the current running process is paused and put back in the waiting queue, and the new process starts executing. In most systems it will automatically interrupt the current running job when the new job arrives, however some systems use a predetermined interval (a certain number of time units), to check for new jobs. • Non preemptive: Take no action when a process with higher priority arrives,when a new process with a higher precedence arrives current running process need to finish first before the new process goes Oxford definition: Preempt – to take action in order to prevent (an anticipated event) from happening; forestall. • Metric: a metric is…
- The ready queue is split into numerous smaller queues using the Multilevel scheduling algorithm, each of which has a different scheduling strategy. You must choose one. What do you think? CPU scheduling software should minimize the amount of time a process spends waiting. I'll give you two options; choose one. Either False OR TrueNon-preemptive scheduling is better suited for supporting a combination of responsive and long- running processes, in comparison to preemptive scheduling. True FalseThis may be accomplished by analyzing the scheduling of processes and threads side by side and comparing and contrasting the two.
- Write a C program which creates a child process to find all txt files in the root directory (i.e., “/") and stores the output in a text file called “all_txt_files.txtť". If the child process execution takes more than t seconds (measured at the parent), the parent should abort the execution of that child. Otherwise, after the child process termination, the parent has to create another child which will count the number of records in all_txt_files.txt and print out the output. The program should not allow the creation of orphan processes. - You need to include the C header file time.h to roughly count the execution time of the child process and play with different values of t so that both cases may happen. Another option may be the alarm system call. - You can use redirection (i.e., “>") to redirect the output of find to a txt file (e.g., find / - name "*. txt" > all_txt_files.txt). It's not a problem if find cannot access some directories. - You can count the number of lines in a txt…Computer Science If a dummy scheduling algorithm is implemented in a C program, and lets the OS schedule all threads regardless of queue size. How would it be considered unsafe? What would need to be done to fix it?Is there a difference between "preemptive scheduling" and "preemptive?"
