TOP REVIEWS FROM 操作系统原理（OPERATING SYSTEMS）

This is an awesome class. It covers basic knowledge of Operating System. Lectures are valuable and homework is not that easy to complete. Try this class and you won't be regret.

课程的内容非常全面，涉及到操作系统的方方面面。视频的长度在10分钟左右，分割成了一个个小的知识点，非常符合MOOC的形式，方便适合自己的速度学习。每周也有一个测验，可以检验学习的效果。然而课程的问题也很明显，作为操作系统课，没有任何实践环节。论坛里没有助教解决问题。即便课程的作业里各种错误，也没有人来更正。不过总的来说，这门课程还是值得一学。

我觉得本课程比较全面的、本课程是有重点地勾勒出来现代操作系统的雏形，操作系统这个话题很多，本课程挑选了几个重要的话题进行探讨，例如CPU的进程/线程管理和调度、线程同步与互斥、内存管理（包括内存空间的分配与回收、页式内存的各类置换策略）、文件系统和磁盘管理等，课程同时结合window/(l)unix的实例去做进一步的说明。

非常实用，在学校老师讲得有的地方不太明白，上Coursera看陈老师的课互补一下立马就懂了。不过个人感觉可以多举例子讲得更深，这样理解会更透彻一些。

课程不过，操作系统的 入门课程，学了还是挺有用的，对操作系统有了基础全面的了解，老师讲课稍微有点照本宣科，对课程的兴趣激发不是很大。

这MOOC比起真正课堂里学的5学分果然还是差距有点大…希望MOOC能尽早赶上课程的真正质量，不要因为面向人群不同就放这么多水啊…

It's a good entry-level course for learning operating system.

为了考研看的，比王道考研那本操作系统多了些东西，课程方面还是挺不错的。可惜期末考试有的题目题干都没有，只能胡填，扣一星。
