40+
对于希望继续学习系统软硬件实现的人来说，本书也是一本很有价值的介绍性读物。大多数系统书籍还倾向于重点关注系统的某一个方面，比如：硬件架构、操作系统、编译器或者网络。本书则以程序员的视角统一覆盖了上述所有方面的内容
41+
42+
43+
它们x86从处理16位字，发展到引人IA32处理器处理32位字，再到最近的X86-64处理64位字。

# Overview.
15+
16+
This book (CS:APP3e) is the third edition of a book that stems from the introductory computer systems course we developed at Carnegie Mellon University, starting in the Fall of 1998, called "Introduction to Computer Systems" (ICS). The presentation is based on the following principles, which aim to help the students become better programmers and to help prepare them for upper-level systems courses:
17+
18+
* Students should be introduced to computer systems from the perspective of a programmer, rather from the more traditional perspective of a system implementer. What does this mean?
19+
* Students should get a view of the complete system, comprising the hardware, operating system, compiler, and network.
20+
* Students learn best by developing and evaluating real programs that run on real machines.
21+
22+
We cover data representations, machine level representations of C programs, processor architecture, program optimizations, the memory hierarchy, linking, exceptional control flow (exceptions, interrupts, processes, and Unix signals), virtual memory and memory management, system-level I/O, basic network programming, and concurrent programming. These concepts are supported by series of fun and hands-on lab assignments. See the manuscript Preface for more details.
23+
Web asides. We had so much material for this book that we couldn't fit it all in! Instead, we have created electronic documents containing useful additional material, which we call Web asides. Check it out. You'll find interesting theoretical and practical information that goes beyond the scope of the book.
24+
25+
**Course Materials for Instructors and Students.** The Student Site contains additional material for the students. The Instructor Site contains a complete turnkey solution for teaching the course.

The CS:APP book presents several examples where the interplay between signed and unsigned arithmetic leads to bugs and security vulnerabilities. A book by Robert Seacord (from the Computer Emergency Response Team) describes a more complete collection of vulnerabilities and provides secure coding guidelines. Note in particular the advice to use unsigned data types for loop indices.
