This Networking Fundamentals course provides a clear and structured introduction to how computer networks operate and how devices communicate over the internet. It is designed for beginners who want to understand the core principles of networking and data transmission.
The course begins with basic concepts such as hosts, IP addresses, and networks, explaining how devices are identified and connected within a network. It then introduces essential networking hardware including hubs, bridges, switches, and routers, and explains how each device plays a role in directing network traffic efficiently.
A major focus of the course is the OSI model, which is used to understand how data moves through different layers of a network. Learners will gain a practical perspective on how each layer contributes to communication between systems.
The course also explains how hosts communicate over the internet, breaking down the step-by-step process of data transmission. It further explores the role of switches in managing local network traffic and how routers handle data routing between different networks.
By the end of this course, learners will have a solid understanding of how networks function, how devices communicate, and how data travels across the internet using structured networking principles. This knowledge is essential for anyone starting a career in IT, networking, or cybersecurity.
