Welcome to the Complete Network Fundamentals Course! In this course, you will learn the technologies that keep the world as you know today connected and running. We cover both the fundamentals of networking as well as the topics in the new Cisco CCNA 200-301 exam.

Networks are all around us and you are using one right now to access this course.

Imagine for a moment, how different your life would be without access to Facebook, Snapchat, Google, YouTube, Whatsapp or any of the other websites on the Internet? How would you live with no Internet?

The Internet is extremely important in modern life today and all websites and Internet communication relies on networking. This reliance is only predicted to continue with the growth of the Internet of Things (IoT) in the next few years.

Without routers, switches, network cabling and protocols like BGP there would be no Internet!

This course will teach you how networks actually work and how you are able to connect to websites like Facebook, Google, and YouTube.

Companies throughout the world (from the smallest to the largest) rely on networks designed, installed and maintained by networking engineers. Join this in demand industry!

Start your journey today learning about networking.

Content in this course can be used towards your CCNA. Topics such as IP addressing, subnetting and many others can be applied directly to passing your CCNA certification.

Access our online simulations so you can practice on simulated Cisco routers and switches. You will get to type commands such as enable, configure terminal, router ospf and many others and learn how to configure devices.

I want to welcome you to this Complete Networking Fundamentals course! I'm David Bombal, and I have been teaching networking  courses for over 15 years. I qualified as a Cisco Certified  Network Engineer (CCIE) in 2003 and hold with numerous other networking certifications. I'm also a Cisco and HPE  certified instructor where I have trained thousands of networking engineers in many of the largest  companies in the world including Fortune 100 companies.

I have designed this course for anyone wanting to learn more about networking and gain foundational knowledge, to help them embark on their networking career. The concepts taught in this course can be applied directly to multiple industry certifications including the Cisco Certified Network Associate (CCNA).

In this course, you will learn about topics such as IP addressing, IP subnetting, Routing, Switches, VLANs, Spanning Tree, Network Address Translation, Wireless and a whole lot more.

You will also learn more about the latest networking trends including OpenFlow and Software Defined Networking.

The course covers the following topics including (and this list will be constantly updated):

  • Network basics

  • Network architectures (OSI Model)

  • What are hubs, switches, routers?

  • How is data forwarded through a network?

  • IP addresses

  • IP subnetting

  • Cabling and network topologies

  • Ethernet basics

  • TCP and UDP

  • DNS and DHCP

  • Routing

  • VLANs

  • Cisco device initial configurations

  • ACLs

  • Network naming

  • IP Telephony

  • Quality of Service (QoS)

  • SDN

At the end of this course, you will be able to confidently discuss networking topics; and be able to start configuring real networking devices such as routers and switches. In this an introductory course, but contains a lot of information that can be directly applied to the CCNA certification.

The ideal student for this course is someone looking to break into the networking field, someone looking to extend their knowledge from PCs and servers to networking, or someone interested in getting knowledge to work in one of the most exciting, most in-demand jobs in IT - networking.

There are no requirements necessary to enroll in this course, I only ask that you come open minded and ready to learn.

Feel free to take a look at the course description and some of the sample free videos.

I look forward to seeing you on the inside!

It was great but moves quite quickly. A lot to take in all at once! I'd like to see maybe some short (5-10 question) quizes at the end of each module to test knowledge as well. Love it!

Sometimes it looks like the professor just got all of his existing videos and put it all together without any order. Just so confused and bored to watch because it's hard to understand like this

I find the course very thural. I have been studying network structures, protocols, binary numbers and hexadecimals before. Being slightly effected by dyscalculia I need visual teaching and repetition for a better understanding. Being a visual learner the way the material is being presented it is a very effective way for me to get to a higher level of understanding and feeling confident about it. It takes me a while working out the numbers due to challenges with arithmetrics but the key to understanding is knowing the roules. This course has definetly delivered above all expectations.

Very good teacher. David makes sure you understand the concepts and doesn't rush or take things for granted. I highly recommend this course.

Terrible, totally unsuitable for an absolute beginner. The biggest problem is a total lack of support and communication from David and the teaching team. How hard is it to reply to questions using the platform (discord) as they request? Pathetic effort.

Even I could not understand everything the author mentioned, I believe I could go back and review later, the most important thing is I was inspired.

The teacher said "please do the lab section by yourself", however there are a lot of new things so I couldn't complete it and I've lost. Don't use command which we haven't known yet in the lab section. And please tell me how to create the Demo networks, or give me the file which works in Packet Tracer.

I have about a year of experience in networking and network programming so im not new in the topic but so far i like where the course is going! Thanks David!
21 October 2021
The material was immense. I loved the idea of the recap section 142. I will definitely go through again to refresh some ideas I haven't grasp well. Loved the course even though I am not interested in CCNA but general networking knowledge and understanding
17 October 2021
I am still in the beginning of the course but so far I am so happy of the contents and they its very detailed and easy to follow, will keep updating as I am progressing!
15 October 2021
Detailed explanation of the course and what to expect. He is quite knowledgeable and passionate in his teaching which is clear and realistic.
30 September 2021
Breaks down content to a layman's level that helps me, who has knowledge, to gain perspective and enforce the terminology.
25 September 2021
Allows me the flexibility to learn at my own pace as well as provided me with hands on walk-thru to better understand network topology.

Great Course , Great Curriculum and Top of it presenting and teaching by an absolutely amazing teacher
1 September 2021
I'm currently studying through the CCNA Official Cert Guide 200-310 volumes 1 and 2, and this course is like an instructor-based visual from the books. David covers every book topic in great detail and he maintains a professional, non-condescending, non-comical demeanor unlike other video instructors. I highly recommend this course and his products.
