Computer Systems: A Programmer's Perspective, Global Edition

Product Information

You read a concept, solve a problem or experiment with a program that illustrates it and then move on to the next concept. It covers a wide range of topics, including computer organization, memory management, virtual memory, network programming, and more. Professor O’Hallaron works in the area of computer systems, with specific interests in software systems for scientific computing, data-intensive computing, and virtualization.

While reading the book, you feel like traveling in the computer world with a smart compass that keeps telling you everything you just need, no more, no less.

One of the strengths of the book is its use of C programming language to illustrate the concepts being presented. By that I don't mean that they don't give you a good overview, they do, but you're always left with this nagging feeling of "But. I have only academic experience with C, yet was able to follow along well enough with the examples adequately. This is an international edition textbook with identical content as the US version and is usually paperback bound instead of hardcover. He has also taught courses in algorithms, programming, computer networking, distributed systems, and VLSI design.

I was not interested in and did not see any benefit for this book to touch on areas of system I/O, network programming and concurrency. If you like me, were left hanging on multiple such foundational topics, and found yourself more than once faced with the fact that we don't necessarily understand the systems we work on at a granular level, and want to do something about it, then you should pick up this book right away. This book strives to create programmers who understand all elements of computer systems and will be able to engage in any application of the field--from fixing faulty software, to writing more capable programs, to avoiding common flaws. Some book may show sales disclaimer such as "Not for Sale or Restricted in US" on the cover page but it is absolutely legal to use.

This book will tell you that assembly is just another programming language, and nothing to shudder at the sight of.

He has taught computer systems courses at the undergraduate and graduate levels for 20 years on such topics as computer architecture, introductory computer systems, parallel processor design, and Internet services.If you're serious about your craft as a software engineer and want to know (out of curiosity and a need for clarity) how things work under the hood, this book is for you. Each chapter starts with some good reasons for actually spending the time to understand the given subject, which is very nice. This book covers all the knowledge that a good programmer needs to understand how his program executes upon the OS and CPU and how to make it efficient, fast and scalable. I highly recommend Computer Systems: A Programmer’s Perspective for anyone who feel they need a better grasp of these ideas. Computer Systems: A Programmer's Perspective" is a highly regarded textbook on computer systems and low-level programming.
