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.

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。

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…

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
