Networking Fundamentals, Straight From a CCNA Course

This free lesson is carved out of a full CCNA 200-301 course and focuses on two foundational frameworks: the OSI model and the TCP/IP model. If you're networking-curious or actively studying for Cisco's CCNA exam, this is where most study plans should start.

The course explains not just what each model's layers are, but why network engineers still argue about them in practice, and why understanding both matters for real-world troubleshooting, not just exam trivia.

Where this fits in a networking career

CCNA is commonly the first certification on the path to becoming a network engineer
The same material overlaps with the CompTIA Network+ exam
Later steps include CCNP or DevNet Associate, and eventually CCIE

Because it's a free excerpt of a paid course, it's a low-risk way to test whether the instructor's teaching style suits how you learn before committing further.

About this course

This is a Free CCNA 200-301 Course that covers the OSI and TCP/IP models. This course covers knowledge that you need for the CCNA exam, but also for the CompTIA Network+ exam. Learn the fundamentals and basics of networking.

Why do you need to learn the TCP/IP and OSI models? Are they important to know? Yes - you need to know these models for both the CCNA exam, but also for the real world.

People in the real world argue about this, but models like the OSI and TCP/IP help with both understanding and network troubleshooting. Make sure you learn especially the TCP/IP model for the CCNA exam.

The Cisco Certified Network Associate (CCNA) is highly recommended as your first certification if you want to become a network engineer. To become a CCNA, you need to pass the CCNA 200-301 exam.

Start with your CCNA exam and then look at furthering your career by becoming a CCNP (Cisco Certified Network Professional) or DevNet Associate.

If you continue with your studies, you could one day become a Cisco Certified Network Expert (CCIE) - one of most highly regarded certifications in the networking industry.
