This course introduces the core fundamentals of computer networking and is designed for beginners who want to understand how modern networks are built and operated. It explains the essential building blocks of networking in a clear and structured way, starting from basic concepts and progressing toward more advanced topics.

You will learn about Local Area Networks (LAN), including how devices connect within small networks and how different network topologies work. The course then breaks down the OSI model, explaining each layer and how data travels through physical, data link, network, transport, and application layers.

It also covers wired and wireless networking, helping learners understand different transmission methods and network media types. A key section focuses on Internet Protocols such as IPv4 and IPv6, as well as how TCP/IP works in real communication systems.

The course further explores important networking services like DHCP, IP assignment (DORA process), remote desktop connections, and security concepts such as IPsec. It also introduces Wide Area Networks (WAN), routing fundamentals, and how networks communicate beyond local environments.

Finally, it explains network infrastructure and security zones, helping learners understand how modern systems are protected and managed.

By the end of this course, learners will have a strong foundational understanding of networking and be ready for advanced IT or cybersecurity studies.
