熟悉操作系统的几种作业调度算法，包括FCFS,SJB以及小作业优先的几种算法，并能够对其进行编程实现。

在后备作业队列中输入5个作业各自运行所需要的时间及存储空间。

　　(1) 按先来先服务的原则进行调度，输出作业调度的顺序及等待的时间和。

　　(2) 按最短作业(即运行时间最短)优先的原则进行调度，输出作业调度的顺序及等待时间和。

　　(3) 按最小作业(即存储空间最小)优先的原则进行调度，输出作业调度的顺序及等待的时间和。

-Some familiar with the operating system, job scheduling algorithms, including FCFS, SJB, as well as several small operations priority algorithm, and be able to achieve their program. Back-up operation in the input queue to run five operating their required time and storage space. (1) First Come First Served scheduling principle, the output of the order of scheduling time and waiting for. (2) by the shortest operation (that is, the shortest running time) the principle of priority scheduling, job scheduling output of the order and wait for the time and. (3) by the smallest operations (that is, the smallest storage space) the principle of priority scheduling, job scheduling output of the order and wait for the time and.
