内容简介
本书自1989 年首次出版以来，曾多次修订。2006 年本书通过了教育部的评审，被纳入普通高等教育“十一五”国家级规划教材；2008 年出版的第5 版获得了教育部2009 年精品教材称号，是“十二五”普通高等教育本科国家级规划教材。现在的第9 版又在第8 版的基础上进行了一些修订。
全书分为9 章，比较全面系统地介绍了计算机网络的发展和体系结构、物理层、数据链路层（包括有线局域网）、网络层、传输层、应用层、网络安全、无线网络和移动网络、新型网络技术等内容。各章均附有复习题和习题。全书课件及其他配套资源放在电子工业出版社华信教育资源网上，供读者下载参考。
本书的特点是概念准确、论述严谨、内容新颖、图文并茂，突出基本原理和基本概念的阐述，同时力图反映计算机网络的一些最新发展。本书可供电气信息类和计算机类专业的大学本科生和研究生使用，对从事计算机网络工作的工程技术人员也有参考价值。
