لسلام عليكم
الرجاء مساعدتى في حل الواجب الذي سوف اوصفلكم اياه
الواجب كا الاتي
The purpose of this project is to write a program that simulates an operating system.
The program implements the following CPU scheduling algorithms.
1. First]Come]First]Serve (FCFS)
2. Shortest]Job]First (SJF)
3. Round]Robin with time slice = 3 (RR]3)
4. Round]Robin with time slice = 5 (RR]5)
The program will read process burst times from a file (job.txt) ] this file will be provided by the instructor.
A sample input file of four jobs is given as follows (burst time in ms).:
[begin of job.txt]
Job1
7
Job2
4
Job3
9
Job4
6
[End of job.txt]
Note: You can assume that
(1) there are no more than 20 jobs in the input file (e.g. job.txt).
(2) processes arrive in the order they are read from the file for FCFS, RR]3 and RR]5.
(3) all jobs arrive at time 0 for SJF.
Compare the average completion times of all jobs for each scheduling algorithm.
Output the details of each algorithm's execution. You need to show which jobs are selected at what
times as well as their starting and stopping burst values. You can choose your display format, but it is
recommended that you display the results in terms of a Gantt chart.
