Course Description

This is a Free CCNA 200-301 Course that covers the fundamentals of how to convert numbers: Binary, Hexadecimal and Decimal. 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.

Do you need to know this? Yes. MAC addresses are written in Hexadecimal. Access lists use binary for matching specific hosts or networks. Routing uses mask (Decimal conversations of Binary numbers) to determine if a host is local, or remote, or for comparing various static routes in a routing table.

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.

Excelente instructor y la app muy sencilla y facil

Pretty good. Rotating the video back and forth could be easier on iPhone. And it'd be nice if we could change how much we wanted the rewind and fast forward buttons to jump thru the video like we can on YouTube. Maybe add a few options like 5 second and 10 second skips instead of only 15 like it has now. But otherwise my overall experience was pretty good.

The beginning clearly and in-depth describes the converting logic that I have been searcing for. Looking forward to learn more

You explained so efficiently and in simple language that I didn't find any problem in learning. I understand everything you taught. Thank you :-)

David with his deep knowledge and his calm voice is one of the best teacher that I have ever had! Many thanks!

By Barry Heath on 6/16/2021

Explained the binary/hex/decimal system and their relationship better than previous instructors I've had, far far less confusing. Am now happily whizzing through conversions with little effort now.
