Perhaps the most critical theoretical component of the ITN course is the study of networking models. Students are introduced to the and the TCP/IP Model . Introduction to Networks (ITN) v7
This section covers:
The course begins by grounding the student in the basics. It covers the global structure of the internet, distinguishing between the "network of networks" and local area networks (LANs). Students are introduced to the and the TCP/IP Model
Before delving into the specific modules, it is important to understand the context of v7.0. The networking landscape changes rapidly. Previous iterations of the CCNA curriculum were often fragmented, with specific tracks for Routing & Switching, Security, and Wireless.
A crucial early concept introduced in ITN is the . Historically, data, voice, and video traveled over separate infrastructures. Today, they share the same pipe. Students learn the requirements for this convergence—specifically, the need for Quality of Service (QoS) to ensure that a large file download doesn't interrupt a critical VoIP call.
