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。当就绪进程个数大于处理器数时，就必须依照某种策略来决定哪些进程优先占用处理器。本实验模拟在单处理器情况下的处理器调度，帮助学生加深了解处理器调度的工作。-In a multi-channel programming systems, tend to have several processes simultaneously in a ready state. When ready to process the number is greater than the number of processors, it must follow certain strategies to determine which process preempt the processor. This experiment simulated the case of a single processor processor scheduling, processor scheduling to help students better understand the work.
