Reddit mentions of Operating System Concepts Essentials

I haven't read it in years, but I remember The C Programming Language being very useful.

If you want to learn more about the low level details of how computers work in general, I own the following books and recommend them:

---

• Low level details on how processors work, memory works, etc:
  Computer Systems: A Programmers Perspective
  Computer Organization and Embedded Systems
  
• Building on the concepts in the above books, this book on hacking also walks through the same concepts from a programmer's perspective. In order to be an effective hacker, it's necessary to understand the low level concepts of how a computer works:
  Hacking: The Art of Exploitation
  
• To understand how operating systems work:
  Operating System Concepts Essentials
  
• To understand computer networking:
  Computer Networking: A Top-Down Approach

I'm not in the course, but I searched google and found this link
