- In this video we provide a formal definition for Network "Protocols". We then briefly describe the functionality of the 8 most common networking protocols on the Internet: DNS, DHCP, HTTP, SSL, TLS, HTTPS, FTP, and SMTP. We follow that with a discussion on the four items which MUST be configured to achieve any sort of Internet connectivity.
This is Lesson 6 of Module 1 of a Networking Fundamentals course. The first module will be released for free on TH-cam and will teach anyone the very core of networking: How data moves through the Internet.

*Full Course Status: Wait and See.*
Hopefully you've come to realize that I put _a lot_ of effort into the content I create. I'm not a course creator that will simply turn on the screen recording and ramble, then call that teaching. I meticulously plan _every_ module and lesson to _maximize the learning and value_ for the student.
To that end, it takes me a while to put together courses. If I'm going to dedicate the time, resources, and energy to putting this full course together, I need to know that there is enough interest in the full course. I'm rating that by how wide a reach this series achieves.
*If you are interested in seeing the full course developed, then the best way to bring that to fruition is to spread the word about this content* . By itself it already conveys _a lot_ of value. So sharing even just the 7 lessons (13 videos) in this series will surely help whoever you share it with.
Plus ... many online communities would greatly benefit from these videos. Think of all the Internet points you could acquire if you shared this series (karma, likes, follows, etc.) 😉

great job. i really enjoy this video and now going back to start the series from start. can you put them on any platform like udemy or anywhere else were we can get certificate of completion as well. much appriecated your efforts
@@PracticalNetworking You're the best. Im going to write my Comptia Sec+ 601 exam. This has been super helpful! Thank you!!!
The BEST teacher on the internet that teaches the internet. Period!
Glad you enjoyed this, Majhool. If you did, you'd probably enjoy the rest of the videos in the Networking Fundamentals series: th-cam.com/play/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi.html
I’m already a fan!!!
I am working to get into Cyber Security and this is the best I have seen on Networking Fundamentals… Thank you very much for sharing your knowledge and experience
This guy is a good teacher
No competition...
Yeah, I love Professor Messer, but he does not teach
Best networking tutorial ever. As a developer I have never gained full understanding of internet protocols, until now.
That's awesome, so glad these have helped you. Thank you for the kind words.
Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
check my video a bout protocols, if it is helpful don't forget to support us th-cam.com/video/TECOBYiA0TE/w-d-xo.html
Watching these kinds of explanations, makes me believe we are closer to getting an internet full of high-quality, pedagogy-oriented lectures, regardless of the topic. What a time to study Computing!
What a time indeed! I hope we get there =)
check my video a bout protocols, if it is helpful don't forget to support us th-cam.com/video/TECOBYiA0TE/w-d-xo.html
I've been on school for about a year now. While I knew all of this by now, this has to be the best quick breakdown I've ever seen! Great work!
I have watched many videos but this is far the best ones and easy to understand. I haven’t seen anyone provide as much examples as you have. For a beginner student, your the best teacher I have seen. Thank you so much, your doing an amazing job.
Sir... your explanation is too good...i am a student and I want to learn more in networking...but on internet there are very few sources which gives simple explanation like this...we all respect your effort...keep doing these networking videos... 🙏🌟🌟🌟🌟🌟❤️❤️❤️
Thank you for the kind words, Vinay. I appreciate your comment!
Same here and definitely agree!
Thank you, Ethen.

I think "too good" is an understatement. The video really broke down these concepts that looked complex at first.
The way you explain the information in detail & examples you use translates extremely well. I'm a baby boomer that's most recently staring my journey of learning IT. Trying to retain & comprehend the language is challenging, but your delivery/presentation of this content has provided me with the hope & desire to continue learning more. Thank you Sir.
Hi Ed,
I am so happy to know your channels. You are still my reference point for all that I know and I am willing to know. Thank you for everything. You are my best teacher!
Thank you for the kind words, Azza. Glad you've found this content helpful!
Thank you so much Ed for these videos. The time and efforts you have put in to build each of these Lessons is truly commendable. You have explained the concepts of each lesson in such simple manner that we would never forget it. It is a great base for anyone working in telecom or networking industry.
I am so Grateful to have stumbled upon this Networking fundamentals course. It has helped in understanding the networking concepts much more clearly than anything else.
If you have any course which explains the RAN networks basically 3G/4G/5G and how a mobile does what it does with network equipments involved for calls/internet/VAS etc. OR how Mobile or Fixed broadband works, please share the link.(It is also fine, if there is no such course. I'm just happy with these available courses)
Thanks for the kind words, R S. Glad you enjoyed this series.
I'm afraid I have no expertise in 3g/4g/5g networks, so wouldn't be the best person to create such a course.
Cheers!
Loving your videos. Far better than the lecturer I currently have. So much time and detail poured into the presentation, but not in a way where it's too convoluted. The whole course is structured perfectly. It's one thing to harbor knowledge on a particular subject, but teaching it to others is truly an artform.
Thank you for the kind words, LJ. Glad you've enjoyed this content.
If you're willing... Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
Love how you simplify everything. Thanks so much!!
I finally understand it now...... Wow , someone who can finally explain it in a non- technical fashion. THANKS
I pride myself on understanding networking! I've been dealing with it in school and somewhat in corporate experience as well - you are such an amazing teacher! Your simplicity of explanation coupled with the animation is phenomenal! I'm subscribing for sure now and I've ran across a few of your videos doing cybersecurity policies and routing and switching research! 👏🏽👏🏽
Hi Jeannette. Thank you for the kind words. Glad Networking makes sense to you =).
This is lesson 6 of a 7-lesson Networking Fundamentals series. In case you haven't seen the rest of the videos, they are all available here: th-cam.com/play/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi.html

Wow! I've been loosely involved in networks and computers for years and I never come across an explanation like this. You explain it so well that it's elegant. Keep up the good work.
Thank you for the kind words, G Force =)
These videos on network fundamental are very illustrative and help even novice to understand the complexity of network and function of network. Demo and graphic make it more interesting and easy to grasp the technical matter.
This is the best networking fundamentals lesson and series I have ever seen. Thank you! Please keep doing what you are doing. I will search your courses first before others.
Clear and concise, good audio and simple understandable terms even for the layman. Thank you and keep on producing excellent content like this. I am sure a lot of people will benefit from it.
Thank you for the kind words, Salem. =)
I just want to say - these videos are a blessing. I'm just now beginning my path to working towards my Network+ and Sec+ Certifications, and the way you explained everything is absolutely amazing. Thank you, thank you, thank you.
Good luck. Don't give up
Sir, you are the best. Selfless teaching, unlike some youtuber teaching business in free TH-cam channel.
Oh wow, I clicked on this with no expectations, but that was very digestible and easy to follow. I love finding nuggets like these
Thank you so much!!! I watched this video out of order but it was definitely such a relatable and clear lesson that helped me visualize what occurs with these protocols! Though I am a Data Science student with goals of breaking into the cyber security industry, I know these lessons here will be very beneficial to my track. Thank you❤❤
So glad this helped you, Angel =). Thank you for the kind words.
PS: You posted this on Lesson 6 of 7... did you get a chance to see the final lesson?
th-cam.com/video/YJGGYKAV4pA/w-d-xo.html
Just wanted to say thank you for making these videos. I've been learning a lot from them and you explain concepts very well! Cheers!
Hi Justin. That's great to hear =). Thank you for the kind words.
I only wish I had seen this video earlier. It has helped bring the networking concepts home by teaching them in a simple and logical manner; demystifying the subject. Many thanks.
Thank you soooo much! Studying for my Sec plus. All the videos I've watched have not helped me understand what you just did in your 12 minute video!!! Greatly appreciated!
One of the most practical series and so easy to understand difficult subject. Please create the full fundamental course, I think whoever will watch it, definitely get benefit from it. Also, if you can have some lesson on i.e Network types on VM, i.e. NAT, Host only etc work & How Kubernetes and WAN technology works in basic , then I will be grateful to you. Thanks a lot
You're welcome again =)
I am a network engineer, and i find these videos very helpful to revisit the basics. Kudos to you!!
Thank you, Shan. Glad you enjoyed these!
the quality of these modules is mind-blowing!!
Never thought that someone can teach in very simple & easy terms. Hats off to you sir. really enjoyed
I don't even speak english but this guy speaks so clean that it's friendly for those who doesn't know a lot but just the basics of english
Glad you enjoyed it, Hefer. THanks for the kind words.
You are genius! I did not understand where to begin, I was so overwelmed with the feeling that it is smth impossible to understand. Your skill to explain fuzzy things in simple manner is amazing. Thank you so much ❤❤❤
Thank you for the kind comment. Glad you enjoy the video! Don't forget to check out the rest of the videos in the Networking Fundamentals series: th-cam.com/play/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi.html
What an incredible lecture! Condensed beautifully into a short video. Kudos!
Your gift of explanation is unique. I now understand this subject clearly for the first time even though I've read it many times. Thanks for your good work
Great vid as always. So far, got my ITF+ and my A+, your lessons helped with both. Next, I'll be going for Network+ and I have no doubt, I'm going to be prepared for it because of your videos.
Fantastic, Thomas. Congrats! Good luck with the Net+
I never heard this simple and easy way of displaying the subject. Thank you very much for your time and effort you made to make this video. It's really very interesting and knowledgeable.
Glad you enjoyed it, Deepak. Don't forget to check out the rest of the videos in the Networking Fundamentals series: th-cam.com/play/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi.html
Hi! Many thx! I had never understood so clearly and completely what is network protocol and how it works! So many thx! So, keep going...please!
What a great way of explaining these concepts! Thank you.
This is a great video and it is much appreciated. You make the breakdown look so easy to understand. I do have colleagues in my IT classes who want to learn as well to get certifications and I will share this with them. Thank you.
Thank you for sharing, Marcos. I appreciate your support!
I am watching this again, like new wine, its evergreen. Thank you.
You are truly a teacher in every sense of the word. You leave no stone unturned while breaking down usually difficult concepts. Do something on ports as well
Thank you for the kind words, Lameck. I briefly mention ports in my OSI model videos: th-cam.com/video/0aGqGKrRE0g/w-d-xo.html
To be honest, it was explained in a really good way that even children would now understand these protocols. I hope to find its full course to get a completion course.
I too hope to make the full course. I'm looking at the view count for every video in the Module 1 series to make a determination of interest. It seems the YT algorithm has particularly favored this video (it has six times the views of the next best video!). The least viewed video is this one, with only 3000~ views: th-cam.com/video/Ep-x_6kggKA/w-d-xo.html
If the least viewed videos get to 10k views ... then maybe I will shift effort to the full course.
this video is like 3 years of computer networking Degree thanks Ed you are absolutely amazing
Cheers Abdirahman =)
This really connect the dots. A must for begineer. I am preparing for AWS certifications and usually comes to youtube to clarify basic concepts and #PraticalNetworking really does the job for me...thank you so much!!
made short and succint, this is one of the best videos to give a crystal clear explanation for the networking protocols that come into play during networking. Thanks for making it.
This was so so well explained and easy to digest! Thank you for putting this together
Thank you, DW =). Glad you liked it!
Well explained. Kudos to you. I hardly like, subscribe nor hit the notification bell but did that for you. More practical and professional videos like yours are what should be online. Time spent here has been useful. Thanks once again for the video.
Thank you for the kind words, John. I appreciate your support!
Presentation itself speaks the quality of this video!
This has been the most comprehensive video on the subject, that I have seen. Good job, bro
very beautifully connected the puzzel pieces at one place to complete the game of most commonly used protocols. i am from IT background for many years, but still found it very interesting point to learn and see all the videos. this is my first video i come across by chance. great job sir.
Thank you for the kind words, lava =). Glad you enjoyed the presentation. Hope you enjoy the rest of the videos in the Networking Fundamentals series as well!

Please keep making these videos for free.
Glad you're enjoying this content. You can help me now by telling your peers about this content =)
Watching this for a job interview on Monday as a network engineer. Need to review everything lol! Thank you !
Excellent!!! Crisp and to-the-point information.
Thank you, Suhas. Glad you enjoyed it!
The video was very clear, concise and complete. I will be using your videos to help with my CCNA course study. Thanks!
WOW! Thank you so much! I have watched and read many different helpful source materials for network protocols but till now I have never come across anything that verbally and visually explains how the protocols relate, as well as refresh my memory on their purpose, etc. It's like I've had a cloud in my mind and this video has removed that cloud! Everyone involved in making this video, thank you so much! I've hit that subscribe button and I'm keeping an eye on my notifications! Awesome work!
Thank you for the kind words, Rob =). It was just me, I'm an individual creator.

Incredible video - a course in this clear concise animated format would be incredible
I think so too =). Hope I get to make it!
You have a nice way to explain things. Can't wait for a course from you, good job!
Thank you for saying so, Steve. =)
Per chance, if you're interested in SSL/TLS, I have created a deep dive course covering those protocols in great depth: classes.pracnet.net/courses/practical-tls
Great course. Always considered myself a technologically handicapped person but your teaching method so interesting and great. Thank you for your effort.
This is fantastic. Thank you Practical Networking.
Thanks alot Sir. I appreciate your efforts to making us a learned community. this is a great class one can ever attend for clarity. thanks again.

By far the best video I've seen on these issues ever - well done
Amazingly on point! I say YES to the course!
Thank you very muchI
Thank you teacher. Best channel.
You're welcome =)
This dude gonna go straight to heaven
Ha! This made me chuckle. Thank you for the kind note.
Everything is so clear. Thank you for producing this material. Really appreciated ☺️
Thank you for this content, it's very useful. Can you do a video contextually explaining how the OSI model, TCP/IP model and Hierarchical design models compliment/don't compliment each other?
The OSI Model and TCP/IP Model are merely models used to describe how Networking works. I talked through the OSI model in these two videos:
th-cam.com/video/LkolbURrtTs/w-d-xo.html
th-cam.com/video/0aGqGKrRE0g/w-d-xo.html
The Hierarchical design from Cisco is something I would expand on in the full Networking course. I did touch on Hierarchies with Routers in this video though:
th-cam.com/video/zmxLg4jV0ts/w-d-xo.html
Glad you enjoyed the content otherwise =)
I love your videos! 🤓
Thank you, SG =).
Wow! Great teacher. Teaches with practical demonstration is the best way possible
Best intro explainer 👍 of DNS domain name system, SM subnet mask, DG default gateway, DHCP dynamic host configuration protocol, and other Internet protocols. Thank you.
great
:)
Thank you, this helped a great deal! Sure I will tell people about your lessons, please keep them coming!
Thank you so much kind sir idk what to say other than flat out "GOD BLESS YOU" for the time energy and effort that went into this master class. I'm all in. 👍🏾👍🏾👍🏾🙏🏾
This was excellent! Very easy to understand and too the point. Thank you so much!
Wow....how did I stumble across this one...Sir you are a gift. Thank you.
Best teacher in networking and explaining things everrr. Hope that course gets created I’ll be sure to spread the word ❤
Thank you so much for this wonderful video. I'm new to this field, trying to learn and have so many questions! Your video has been very helpful. Appreciate all your work and your simplicity in teaching this content.
you are a hell of a teacher. Thank you so much. God bless you.
This is a great demonstration of network fundamental knowledge.
Excellent summary of these protocols. Thanks very much.
Coming from a non-networking background, I can't thank you enough for demystifying these topics. I would humbly request you to keep educating us! Thanks again!

I'm new to this and I'm still at gather all the information I can mode. I'm growing as is my network. Currently setting up gig speed from the Antenna to the router to a 24 port poe switch. Access point outside, to supply to the pump house for an arduino system a number of itens along with one in the barn. The barn has cat5e feeding to the house. CCTV 16 camera 720p unit running in the barn. The house will control the CCTV requiring wired, wireless, and ip cameras. Computers, laptops, print server, Network storage, and various sensors located about the property. That is an overview of where it is going. I'm teaching myself and learning from these videos. Please keep them coming.
Thanks,

It's great that you can take these videos and go directly to implementing something on your home network. Good stuff, Randy. Glad you've enjoyed them!
I truly appreciate how you break it down to basic there was a lot I learnt from that video. To me I believe it is done in the simplest form,you are an excellent teacher.It also demonstrated to me that you fully understand the topic
