说明：  作业调度——先来先服务，最短作业优先，最高响应比优先(Job scheduling- a first-come first-served, shortest job first, highest priority response ratio)

操作系统的实验文档 包含设计与说明 带源码例子(Document contains the operating system design and description of experimental)

本教材以操作系统原理为主线，结合当今主流操作系统设计方法。(The principles of materials to the main line operating system, combined with today' s mainstream operating system design.)

说明：  可变分区，一个很重要的操作系统原代码，很详细的拉，个人下载参考参考。(Variable Division, a very important source operating system, a very detailed and pulling personal information. Download.)

加深进程概念的理解；掌握选择进程调度算法的准则；掌握进程调度算法。 (Deepen the process of understanding of the concept master scheduling criteria selection process algorithm master process scheduling algorithm.)

HPA就是host protect area(HPA is the host protect area)

开发一个仿真操作系统，要求具备进程调度、存储器管理、文件及设备管理等基本功能(The development of a simulation operating system, requires scheduling process, the basic functions of memory management, file and device management)

作业调度程序，模拟操作系统的作业调度过程，协调和控制各个作业对cpu的使用控制(Job scheduling program to simulate the process of the operating system job scheduling, coordinating and controlling the use of control operations on cpu)

说明：  几个算法分析和操作系统的上机小程序，vc,c#实现(several algorithm analysis and operating systems on the plane small program vc, c#)

1．虚拟存储器的引入 局部性原理：程序在执行时在一较短时间内仅限于某个部分；相应的，它所访问的存储空间也局限于某个区域，它主要表现在以下两个方面：时间局限性和空间局限性。 2．虚拟存储器的定义 虚拟存储器是只具有请求调入功能和置换功能，能从逻辑上对内存容量进行扩充的一种存储器系统 (1. The introduction of virtual memory locality principle: program execution in a relatively short period of time limited to a particular part of it Accordingly, it has access to the storage space is also limited to a particular region, it is mainly manifested in the following two aspects: the time limitations and space limitations. 2. The definition of virtual memory Virtual memory is just a request for redeployment of functions and displacement functions, from the logical to expand the memory capacity of a memory system)
