For processes with the same priority, a round-robin scheduler will be used with a time quantum of 3 time units. If a process is preempted by ahigher-priority process, the preempted process is placed at the end of the queue.(a) Show the scheduling order of the processes using a Gantt chart.(b) What is the turnaround time for each process?(c) What is the waiting time for each process?

MINIX Programming Modify the MINIX 3 scheduler to keep track of how much CPU time each user process has had recently. When no task or server wants to run, pick the user process that has had the smallest share of CPU.

TASK1: DESCRIPTION One of the simplest methods for memory allocation is to divide memory into several fixed-sized partitions. Each partition may contain exactly one process. In this multiple-partition method, when a partition is free, a process is selected from the input queue and is loaded into the free partition. When the process terminates, the partition becomes available for another process. The operating system keeps a table indicating which parts of memory are available and which are occupied. Finally, when a process arrives and needs memory, a memory section large enough for this process is provided. When it is time to load or swap a process into main memory, and if there is more than one free block of memory of sufficient size, then the operating system must decide which free block to allocate. Best-fit strategy chooses the block that is closest in size to the request. First-fit chooses the first available block that is large enough. Worst-fit chooses the largest available…
Scheduling Algorithms This project involves implementing several different process scheduling algorithms. The scheduler will be assigned a predefined set of tasks and will schedule the tasks based on the selected scheduling algorithm. Each task has an arrival time and is assigned a priority and CPU burst. The following scheduling algorithms will be implemented: First-come, first-served (fcfs), which schedules tasks in the order in which they request the CPU . Shortest-job-first (sjf), which schedules tasks in order of the length of the tasks’ next CPU burst. Priority scheduling (pri), which schedules tasks based on priority. Round-robin (rr) scheduling, where each task is run for a time quantum (or for the remainder of its CPU burst). Priority with round-robin (pri-rr), which schedules tasks in order of priority and uses round-robin scheduling for tasks with equal priority. Priorities range from 1 to 10, where a higher numeric value indicates a higher relative…
