Operating system principle notes. Thanks to Mr. Su Shuguang.
请注意：本笔记仅供学习和参考，若出现任何由参考本笔记上内容导致的错误，笔者概不负责！！
本笔记的主要内容来源是苏曙光老师上课教授的内容与其使用的PPT，也参考了苏曙光老师编著的教材和互联网上的部分资料。笔者实力与水平有限，内容难免有疏漏与错误。
本笔记的出发点十分简单，是为了便于大家学习，交流，复习《操作系统原理》这门较为复杂的课程。但在一段时间来，我对*同学的考前突击辅导收效甚微。而且同学们求学的热情确实也令我十分汗颜，但笔者时间有限，笔者的辅导难以做到尽善尽美。这个项目希望能成为一个开端——软件学院同心同力，分享知识与方法，实现“传帮带”作用，这也是我的一次尝试！
所以本笔记在内容上，希望能尽量在正文详细地诠释每一个概念与过程，便于考前突击和自学的同学使用。但对于知识掌握较好的同学，可以采取按照目录复习的方式，本笔记将在格式上尽量做到纲举目张，将核心概念，核心内容全面的展示在目录中。所以本笔记希望达到的目标是既详实又精炼，既基础又提高。
