Why take 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.

This course is part of my full CCNA course on Udemy. I've made this part of the course free (and others) so you can start learning today and change your life. Don't wait. Start studying today.

Good to remember: All People Sleeping Through Networking Don't Pass : Application, Presentation, Session, Transport, Network, Data Link, Phisical

This course presented a moderate learning experience, albeit falling short of my initial expectations, considering its complimentary nature. The initial four videos seemed to reiterate the same content excessively, resulting in a lack of substantial relevance. However, it did manage to deliver a satisfactory outcome, given its free nature. Notably, the fifth video provided the most comprehensive and enlightening explanation throughout the entire course.

Better than my university professors. This is the kind of learning I've always wanted. And, his style of teaching is what I've always wanted too. Physical demonstration of apparatus needed, full exploration of tools, and also the breakdowns of all complex definitions make it easy for us to understand. I've always counted on David sir for any IT-related curiosity of mines. I always hope to get a video regarding the topic I search for on YouTube. I wish if I've known him earlier. Anyway, thanks a ton David sir.

I really like this instructor. He's very clear and explains topics very well. I find him interesting so, that's good and made the course easier for me. I've watched some of his YouTube videos and plan to take more of his Udemy courses at some point. Thank you very much!
