“Very good explanation of all the learning materials. He is unlike many other instructors who just throws things out to you expecting you to absorb the things that are being thrown at you. He is someone who explains things in a manner that is understandable and absorbable even to O/S beginners with only limited knowledge or background in O/S. Two thumbs up from me! Thank you so much!” by Mike

I look forward to Part 2” by John Simons
“我真的很喜欢这门课程，讲师很好地概述了操作系统背后的理论基础。如果您感到困惑，该课程是理论性的，而不是如何使用Windows，Mac等的演练。相反，他概述了用于将进程从 RAM 移动到 CPU 的算法。我期待第2部分“约翰·西蒙斯
