This Computer Networking Fundamentals course provides a complete introduction to how modern computer networks are designed, built, and managed. It is ideal for beginners who want to understand the core concepts of networking and how different systems communicate with each other.

The course begins with Local Area Networking (LAN), explaining basic network structure, topologies, and how devices are connected within a local environment. It then introduces the OSI model, breaking down how data travels through different layers, from physical transmission to application-level communication.

Learners will explore both wired and wireless networks, including the types of media used and how wireless communication functions in real-world environments. The course also covers Internet Protocol (IP), including both IPv4 and IPv6, which are essential for identifying and communicating between devices.

A key section focuses on TCP/IP tools and command-line usage, helping learners understand how network communication is tested and managed in practice. It also introduces important networking services such as DHCP, remote desktop, and IP security (IPsec).

In addition, the course explains wide area networks (WANs), routing concepts, and how data moves across large-scale networks. It also introduces network infrastructure and basic security principles, including security zones and protective devices.

By the end of this course, learners will have a strong foundation in networking concepts, protocols, and security basics needed for further IT and networking studies.
