time

代码说明：

  按时间片轮转法实现处理器调度的进程：在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态。但就绪进程个数大于处理器的个数是，就要求依照某种策略决定那个进程优先占用处理器。的处理器调度，帮助学生加深处理器调度的工作(Press round-robin method to achieve processor scheduling process: the introduction of multi-channel programming system, often there are a number of processes at the same time a state of readiness. But the number of runnable processes is greater than the number of processors that would require that the process in accordance with a policy decision to preempt the processor. Processor scheduling, to help students better processor scheduling work)
