**电信网络基础 (Learn Basics of Telecommunication Networks) 课程总结** 本课程深入浅出地介绍了电信网络的基础知识。课程始于对传统电话交换网 (PSTN) 的演进的回顾，随后重点讲解了服务提供商在固定和无线网络方面的网络架构。 课程以核心层 (Core)、汇聚层 (Aggregation) 和接入层 (Access) 的层级结构来解释网络架构。网络本质上是计算机及其他设备（包括客户端计算机、服务器以及集线器、交换机、路由器和防火墙等网络设备）之间的通信或互联。 学员还将学习网络组件、网络拓扑、传输介质以及 TCP/IP 协议栈。此外，课程详细探讨了开放系统互连 (OSI) 模型，这是一个用于理解和解释网络协议的理论框架。OSI 模型旨在实现不同系统间的开放通信，而无需更改底层软硬件的逻辑。OSI 的各层相互独立，这使得引入更改更为便捷，因为不会影响其他层。课程详细讲解了 OSI 各层及其功能。 最后，课程以与频率和频谱相关的无线接入基础概念作为结语。课程结尾的评估测验将帮助学员检验学习成果。
Telecom Network Architecture course starts with evolution of the legacy PSTN networks. The course covers Network Architecture for Fixed and Wireless networks for a Service Provider. The architecture is explained using hierarchy like Core, Aggregation and Access. Networking is basically communication or an interconnection of computers and other devices including client computers, servers and, network devices, such as hubs, switches, routers, and firewall. Participants will also learn about network components, network topologies, transmission media and TCP/IP protocol suite. The course covers Open Systems Interconnection or OSI model, which is a theoretical framework for understanding and explaining networking protocols. The purpose of the OSI model is to open communication between different systems without any changes to the logic of the underlying hardware and software. All OSI Layers are independent from each other, which makes introducing changes easier as no other layers are effected. The OSI model has been discussed giving good understanding of the different layers and their functionalities in detail. The course learning concludes with the wireless access basic concepts related to frequency and spectrum. The assessment quiz at the end will help participants to check their learning.
