This Computer Networking Fundamentals course provides a complete introduction to modern networking concepts and technologies. It is designed for beginners who want to understand how computer networks operate and how secure communication systems are built.

The course begins with Local Area Networking (LAN) fundamentals, including network topologies, network design, and the basic building blocks of computer communication. Learners explore how devices connect and communicate within local and enterprise networks.

A major focus of the course is the OSI model, where students learn the functions of each networking layer from the physical layer to the application layer. The course explains switches, routing, transport protocols, and session management in a practical and easy-to-understand way.

Students also learn about wired and wireless networks, network media types, and internet protocols including IPv4 and IPv6. Practical TCP/IP command-line tools and networking diagnostics are introduced to help learners understand real-world troubleshooting techniques.

Additional topics include DHCP, DORA process, Remote Desktop, IPSEC, WAN technologies, routing concepts, and network infrastructure security. The course also explains security zones and devices used to protect networks from threats.

By the end of this course, learners will have a strong foundation in networking, network security, and internet communication systems.
