This Networking Fundamentals course provides a complete introduction to how computer networks operate and how devices communicate across the internet. It is designed for beginners who want to build strong foundational networking skills for IT, cybersecurity, or system administration careers.
The course begins with essential networking concepts such as hosts, IP addresses, and network structures. Learners understand how devices are identified on networks and how data is transferred between systems.
Students are introduced to important networking devices including hubs, bridges, switches, and routers. The course explains the role of each device and how they manage and direct network traffic efficiently.
A major focus of the course is the OSI model, which provides a practical framework for understanding network communication layers. Learners explore how data moves through different layers, from physical transmission to application-level communication.
The course also explains what hosts, switches, and routers actually do during communication over the internet. Topics include packet forwarding, MAC addresses, switching behavior, and routing processes used to deliver data between networks.
By the end of this course, learners will have a strong understanding of networking fundamentals, network devices, and internet communication processes. This knowledge forms the foundation for advanced networking certifications and careers in IT infrastructure and cybersecurity.
