The Complete Networking Fundamentals Course. Your CCNA start

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'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 moreabout networking and gain foundational knowledge, to help them embark on theirnetworking career. The concepts taught in this course can be applied directlyto multiple industry certifications including the Cisco Certified NetworkAssociate (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

highly recommended

Highly recommended!

Highly Recommended.

Highly recommended.

The instructor provide the information clear, the technical language is easy to understand, in my case the English it’s not my language and to me it’s very important the fluent, speech and accent of the instructor, highly recommended this training It's a bit to early to rate, but so far the instructor knows what he is talking about, gives you a little bit of history, while telling you why was bad or good that some things happened.

highly recommended The videos have a lot of information and it helps a lot to understand better good explanations with examples so far its been 5-6 2 min Clips.

Very well thought out course It’s so easy to follow one video after another !!

Videos are clear, well thought out and full of great content.

the pace, presentation and content is well thought out and orderly.

Easy to follow and well thought out The instructor provides access to simulations which gives students real world hands on experience.

packet tracer

I'd recommend to start using GNS3 and/or Packet Tracer right from the beginning of the course and try out along the way the labs David demonstrates.

I have not used GN3 but I have packet tracer to practice in.

I can also recommend his packet tracer and GNS3 labs as well as the "Python Network Programming for Network Engineers course".

The practicals are explained using Wire shark and Cisco packet tracer tools.

I think this should have been kept simple either-1 single course or 2-separate courses(icnd1&2) this way we don't have to think what course to study & compare & think that have we missed anything from some other course, i think similar thing has happened with the Packet tracer free & paid-Ultimate courses, there also, majority of the videos are same in the free course.

Easy to understand Great way of explaining concepts I have experience from a free packet tracer course and quite enjoy it, So I decide to buy this course.

broken down

Information is broken down into elementary terms for a better understanding.

Everything is explained so well with very good analogies and concepts broken down to be easily understood.

I'm the type of person who likes to have a lot of information broken down to me in the simplest terms, and he does a great job at this It is a good course for people trying to enter Networking field.

Although I knew most of the information in the first part, it was very well explained and broken down into simple terms that are very easy to understand.

Material is broken down into manageable sizes.

Its broken down into easy to understand pieces so you won't get off track!

Very simplistic and broken down slowly for the complete beginner to understand.

subject matter

Very thorough and clear explanations of each and every aspect of the subject matter.

There have been a couple of times so far where he has perhaps overindulged and complicated a topic but mostly he is doing a very good job of breaking the subject matter down into easily understandable components.

About the content & delivery method, David is good knowledgeable, experienced about the ccna subject matter, since ccna syllabus itself is quite vast like all cisco certs from exam point of view, you might feel bored at a point but you need to carry on to complete it if you are serious abt getting certified.

The instructor is knowledgeable about the subject matter and clearly explains every concept.

He instructs very well with clear and concise communication of the concepts and ideas of the subject matter.

The instructor explains everything so the student can very clearly understand what he is saying (his voice and pace) and what he is talking about (the subject matter).

real life

David is very knowledgeable and is able to both explain networking concepts in an easy way, but provide real life use cases, backstory and hands on experience that one only would get by being in the business.

i love how everything he explained had a real life example which made it easier to get the concept Excellent visuals and solid explanation.

Great course, lots of content 5/5 very clear and I like the presentation clear intro with real life examples like home router and traffic The lecturer is very effective at communication and is able to relate technical concepts to every day procedures that a lay person would be familiar with.

starting from the basics and taking real life examples is the best way to teach.

very good slow explinations concepts are simplified and they were related to real life examples.
