 The course impressed me for two aspects:
 
-Firstly, the textbook: *Operating Systems: Principles and Practice (2nd Edition)*Four volumes, written in great depth, but easy to understand, well compensated for the little blank in the theoretical knowledge of MIT6.S081, I highly recommend you to read this book.
