本书是关于操作系统的权威教材。大多数关于操作系统的图书均重理论而轻实践，而本书则在这两者之间进行了较好的折中。本册详细探讨了操作系统的基本原理，包括进程、进程间通信、信号量、管程、消息传递、调度算法、输入、输出、死锁、设备驱动程序、存储管理、调页算法、文件系统设计、安全和保护机制等；此外，还详细讨论了一个特殊的操作系统MINIX 3（一个与UNIX兼容的操作系统），并提供了该系统的源代码（见本书下册），以便于读者仔细研究。这种安排不仅可让读者了解操作系统的基本原理，而且可让读者了解到这些基本原理是如何应用到真实的操作系统中去的。
本书适用于高校计算机专业的学生，也可供程序设计人员、工程技术人员、系统架构师等相关人员参考。

TCP/IP Illustrated, Volume 1, Second Edition, is a detailed and visual guide to today’s TCP/IP protocol suite. Fully updated for the newest innovations, it demonstrates each protocol in action through realistic examples from modern Linux, Windows, and Mac OS environments. There’s no better way to discover why TCP/IP works as it does, how it reacts to common conditions, and how to apply it in your own applications and networks.
Building on the late W. Richard Stevens’ classic first edition, author Kevin R. Fall adds his cutting-edge experience as a leader in TCP/IP protocol research, updating the book to fully reflect the latest protocols and best practices. He first introduces TCP/IP’s core goals and architectural concepts, showing how they can robustly connect diverse networks and support multiple services running concurrently. Next, he carefully explains Internet addressing in both IPv4 and IPv6 networks. Then, he walks through TCP/IP’s structure and function from the bottom up: from link layer protocols–such as Ethernet and Wi-Fi–through network, transport, and application layers.
Fall thoroughly introduces ARP, DHCP, NAT, firewalls, ICMPv4/ICMPv6, broadcasting, multicasting, UDP, DNS, and much more. He offers extensive coverage of reliable transport and TCP, including connection management, timeout, retransmission, interactive data flow, and congestion control. Finally, he introduces the basics of security and cryptography, and illuminates the crucial modern protocols for protecting security and privacy, including EAP, IPsec, TLS, DNSSEC, and DKIM. Whatever your TCP/IP experience, this book will help you gain a deeper, more intuitive understanding of the entire protocol suite so you can build better applications and run more reliable, efficient networks.
