**课程名称：** 计算机网络基础 (Computer Networks Fundamentals) **课程概述：** 本课程旨在帮助学习者全面掌握计算机网络的基础知识。课程将以通俗易懂的理论讲解和实践案例相结合的方式进行。课程结构遵循OSI（开放系统互连）模型，详细剖析其七个层次： 1. **物理层 (Physical Layer - L1)**：负责传输比特流，涉及硬件、电缆、接口等。 2. **数据链路层 (Data Link Layer - L2)**：负责在相邻节点之间进行可靠的数据传输，处理帧、MAC地址、错误检测等。 3. **网络层 (Network Layer - L3)**：负责数据包的寻址和路由，处理IP地址、路由器等。 4. **传输层 (Transport Layer - L4)**：负责端到端的数据传输，提供可靠或不可靠的服务，处理TCP/UDP、端口号等。 5. **会话层 (Session Layer - L5)**：负责建立、管理和终止应用程序之间的通信会话。 6. **表示层 (Presentation Layer - L6)**：负责数据的格式化、加密和解密，确保数据在不同系统间的兼容性。 7. **应用层 (Application Layer - L7)**：为用户提供网络服务，如HTTP、FTP、DNS等。 在深入讲解完OSI模型的七个层次后，课程还将额外涵盖**计算机网络安全、移动网络和无线网络**等热门主题。 **课程价值：** 掌握计算机网络知识能够显著提升职业前景。网络专业人士可担任网络工程师、网络架构师、计算机安全专家以及网络与计算机系统管理员等职位，该领域就业机会众多。 此外，本课程可作为计算机网络安全的入门介绍。了解计算机网络基础是从事网络安全相关工作的强制性先决条件，将大大增加您获得网络安全职位的机会。 **互动与反馈：** 本课程鼓励学习者积极互动，可在问答区提问，或通过私信交流。任何关于增强学习内容或补充新主题的建议都将受到欢迎。
Computer Networks Fundamentals is a course that will help you get off the ground with your Computer Networks knowledge, with easy-to-understand theoretical lessons and some practical examples. In this course, the OSI (Open Systems Interconnection) model is used, following its 7 layers:1. Physical Layer (L1)2. Data Link Layer (L2)3. Network Layer (L3)4. Transport Layer (L4)5. Session Layer (L5)6. Presentation Layer (L6)7. Application Layer (L7)We will use that same order, and as a bonus, after we've thoroughly covered all 7 OSI layers, we'll also cover the topics of Computer Network Security, Mobile, and Wireless Networks too.Computer networking knowledge is likely to improve your career prospects. Network professionals may work as network engineers or network architects, computer security specialists, or network and computer systems. Either way, opportunities in this field are plentiful.You may also use this material as an introduction to Computer Network Security, which has been in focus lately. For the jobs offered in that area, knowing Computer Networks fundamentals is a mandatory pre-requisite, and will greatly improve your chances of getting a role in cybersecurity some day.As in every Cyber Quince course, you're welcome to ask questions both in the Q & A section, and via direct messages. Any suggestions and requests for additional topics to be covered will also be appreciated!
