The book is a great introduction to system design issues that are only taught at few courses in few universities. even-though they show up in computer systems everywhere. This is a very good and easy read for any one in computer industry . it describes all parts of computer systems and how they interact very well. The extension of the book is online and many chapters are available for free to download.
The chapter on Naming is worth the money of the book. I have not seen the discussion of naming in such detail and simple terms anywhere,
The authors are very well respected professors at MIT and have experience in operating systems and computer system since its early days.

I highly recommend this book to any hardware or software student or professional engnineer.

这本书是对系统设计问题的一个很好的介绍，这些问题只在少数大学的少数课程中讲授，尽管它们在计算机系统中到处出现。对于计算机行业的任何一个人来说，这是一本非常好的、容易阅读的书。它很好地描述了计算机系统的所有部分以及它们如何相互作用。该书的扩展部分是在线的，许多章节可以免费下载。

关于命名的章节是值得这本书的钱的。我没有在任何地方看到过对命名的讨论如此详细和简单。

作者是麻省理工学院非常受人尊敬的教授，从早期就有操作系统和计算机系统方面的经验。

我强烈推荐这本书给任何硬件或软件学生或专业工程人员。
