Computer Systems: A Programmer's Perspective, Global Edition
About this deal
I found the time well-spent in deepening my understanding of how computers actually run programs and why higher-level languages like Python necessarily sacrifice some performance. I had a lot of experience programming before reading this, but the book definitely clarified my thinking on many topics.
But it will take some discipline and effort to go through it and complete all the assignments (it took me two years studying this on weekends), but you will come out with much joy and satisfaction at the end of it. Having read for breadth and gleaned a low-resolution understanding of the topics, I imagine I will revisit this as-needed for deeper reference throughout my future studies and career (and have already encountered a couple real-world problems where this lower-level knowledge has helped me debug and find solutions). It covers a wide range of topics, including computer organization, memory management, virtual memory, network programming, and more.It's written for computer science students, and goes into a lot of detail about modern operating systems concepts such as virtual memory, processes, and signals.
Computer systems: A Programmer’s Perspective explains the underlying elements common among all computer systems and how they affect general application performance. Probably didn't learn as much as CMU's course but it was a good enough "systematic" intro to systems. This actually did a lot for me, but I had to put many, many hours and days into it to get just the overarching concepts. I have only academic experience with C, yet was able to follow along well enough with the examples adequately.Professor O’Hallaron works in the area of computer systems, with specific interests in software systems for scientific computing, data-intensive computing, and virtualization.
All the chapters are excellent, except maybe chapter 7 on linking and chapter 8 on exceptional control flow.I highly recommend Computer Systems: A Programmer’s Perspective for anyone who feel they need a better grasp of these ideas. The book is well-written, comprehensive, and highly accessible, making it a great choice for both students and professionals. And you walk away not just with a solid understanding of the concepts but also an almost reverent appreciation for the beauty of these complex systems. The code examples are well-written, easy to understand, and provide a practical context for the theoretical concepts being discussed.
is the newest version, does not mention SSL and talks about Telnet, rather than SSH) and more low level than I expected. One of the strengths of the book is its use of C programming language to illustrate the concepts being presented.While the content is not too hard, the knowledge in here is definitely not attainable from random tutorials here and there on the web.
