Network Fundamentals is a comprehensive introduction to Ethernet networking designed for manufacturing and industrial environments. The course is built around the Open Systems Interconnection OSI standard and uses it as the foundation to connect closely related concepts such as subnetting, traffic types, and network behavior. By tying these ideas back to the OSI model, attendees gain a deeper understanding of how industrial networks actually function and where issues commonly occur.

Throughout the course, you will learn how IT and OT priorities differ and how those differences impact network design on the plant floor. You will explore common network topologies, redundancy methods, and traffic varieties that influence performance and uptime. The training also covers managed switch features, basic configuration concepts, and a practical approach to securing industrial networks using the NIST Cybersecurity Framework. By the end of the course, you will have the confidence to troubleshoot network issues, support reliable Ethernet infrastructure, and make informed decisions that reduce downtime and improve operational resilience.
