title: scheduling order (timeline) for FCFS, SJN, SRT, Round Robin
body: <p>I got this question from my friend, new to the operating system area. </p>
  
  <p>We got:</p>
  
  <p>Job number 1<br>
  Arrival Time = 0, CPU cycles = 80,</p>
  
  <p>Job number 2<br>
  Arrival Time = 22, CPU cycles = 60,</p>
  
  <p>Job number 3<br>
  Arrival Time = 44, CPU cycles = 24,</p>
  
  <p>Job Number 4
  Arrival Time = 55, CPU cycles = 40.</p>
  
  <p>How can I do the scheduling order for FCFS, SJN, SRT, Round Robin (using a time quantum of 20).</p>
  
  <p>Thank you. If you can give me any ideas...</p>
