title: Cooperative Scheduling vs Preemptive Scheduling?
body: <p>In the book <em>Core Java : Volume 1 Fundamentals -> chapter MultiThreading</em> . </p>
  
  <p>The Author wrote as follows :</p>
  
  <blockquote>
    <p>"All modern desktop and server operating systems use preemptive
    scheduling. However, smaller devices such as cell phones may use
    cooperative scheduling...."</p>
  </blockquote>
  
  <p>I am aware of the definitions/workings of both types of scheduling , but want to understand  reasons why cooperative scheduling is preferred over preemptive in smaller devices.</p>
  
  <p>Can anyone explain the reasons why ? </p>
