随着信息技术的飞速发展，计算机网络已经成为现代社会不可或缺的基础设施之一。无论是个人日常生活还是企业运营，都离不开计算机网络的支撑。因此，掌握计算机网络的基础知识和应用技能，对于计算机及相关专业的学生及广大计算机爱好者来说，都显得至关重要。
为了满足广大读者对计算机网络技术的学习需求，我们编写了这本全面、系统、实用的《计算机网络实用教程（微课视频版）》教材，旨在帮助读者全面、系统地了解计算机网络的基础知识和应用技能。本书以设计一个类似因特网的多场景复杂网络项目为贯穿始终的情境载体，将家庭网、无线校园网、企业网（包括公司总部和分公司）、移动网、网络服务器等相关知识融合为一个有机的整体。本书通过一系列精心设计的实验，帮助读者从零开始建立对计算机网络的深入理解和应用能力。每个实验都围绕一个具体的主题展开，引导读者逐步理解和掌握计算机网络的基本原理、关键技术及实际应用，通过项目实践帮助读者将理论知识与实际操作相结合，提高解决实际问题的能力。
本书注重层次性和系统性，遵循由浅入深、循序渐进的原则，从计算机网络的基础概念入手，逐步深入高级应用，引导读者走进计算机网络的世界。全书共分为十章，涵盖了从项目准备到网络服务器部署、从局域网搭建到广域网接入等多方面的内容，逐步深入讲解了局域网的组建、路由配置、VLAN 间通信、网络服务器部署、网络地址转换、协议分析、无线局域网搭建及广域网接入。书中穿插了相关的理论知识，对关键概念和原理进行解析，帮助读者建立起完整的知识体系。通过大量的实验，读者可以亲自动手实践，加深对理论知识的理解。
本书设计的所有实验均在 Cisco Packet Tracer 网络仿真系统上进行。
本书提供了配套电子课件、教学大纲、习题及答案等多种教学资源，以及 46 段教学视频、112 张命令详解图片，读者在学习的过程中，扫描二维码可以观看视频和命令详解，帮助读者更加直观地理解和掌握相关知识和技能。
本书由高校教师、北京邮电大学计算机博士张同光担任主编，由高校教师李尊、李帅、薛艳和田乔梅担任副主编。张同光编写第 2～4 章，李尊、李帅、薛艳和田乔梅共同编写第 1 章、第 5～10 章。全书由张同光统稿和定稿。
本书得到了河南省科技攻关项目（NO.242102321148）、网络与交换技术全国重点实验室开放课题（SKLNST-2024-1-11）的支持，在此表示感谢。
在编写本书的过程中，得到了电子工业出版社薛华强编辑的大力支持和帮助，在此表示衷心的感谢。
由于编者水平有限，书中欠妥之处敬请广大读者和同行批评指正。
