Description: 一、目的要求
用高级语言编写和调试一个或多个作业调度的模拟程序，以加深对作业调度算法的理解。
二、例题：为单道批处理系统设计一个作业调度程序。
由于在单道批处理系统中，作业一投入运行，它就占有计算机的一切资源直到作业完成为止，因此调度作业时不必考虑它所需要的资源是否得到满足，它所占用的 CPU时限等因素。
作业调度算法：采用先来先服务（FCFS）调度算法，即按作业提交的先后次序进行调度。总是首先调度在系统中等待时间最长的作业。
-First, the purpose of high-level language requires writing and debugging of one or more job scheduling simulation procedures in order to deepen their understanding of job scheduling algorithms. B, Example: In order to single-channel system, the design of a batch job scheduling procedures. Road as a result of a single batch system, the operation of a put into operation, it would occupy all the resources until the computer s operation has been completed, so no need to consider when scheduling operation of the resources it needs are met, it is occupied by factors such as CPU time limit. Scheduling Algorithm: The First Come First Served (FCFS) scheduling algorithm, that is, according to the order of operations submitted for scheduling. Scheduling is always first in the system waiting for the longest operations.

Description: 作业调度---实验报告
一、实验目的：
本实验要求用高级语言（C语言实验环境）编写和调试一个或多个作业调度的模拟程序，了解作业调度在操作系统中的作用，以加深对作业调度算法的理解
二、实验内容：
1、编写并调试一个单道处理系统的作业等待模拟程序。（必做）
作业调度算法：
分别采用先来先服务（FCFS），最短作业优先（SJF）、响应比高者优先（HRN）的调度算法。
（1）先来先服务算法：按照作业提交给系统的先后顺序来挑选作业，先提交的先被挑选。
（2）最短作业优先算法：是以进入系统的作业所提出的“执行时间”为标准，总是优先选取执行时间最短的作业。
（3）响应比高者优先算法：是在每次调度前都要计算所有被选作业（在后备队列中）的响应比，然后选择响应比最高的作业执行。-df g d fd g ag d g s g dg

Description: FIFO is an acronym for First In, First Out, an abstraction related to ways of organizing and manipulation of data relative to time and prioritization. This expression describes the principle of a queue processing technique or servicing conflicting demands by ordering process by first-come, first-served (FCFS) behaviour: where the persons leave the queue in the order they arrive, or waiting one s turn at a traffic control signal.
