Each layer of the OSI model and TCP/IP explained.

[@TobyChugg]

8 hours worth of lecture content from the university I attend in 20 minutes and it's more clear. Thank you for the time and effort you put into this fantastic video.

[@stephenwalker700]

Same here....

[@danscourses]

Awesome!

[@DaggerMan11]

Honestly, these short, well-explained lectures are the best way to learn the fundamentals. Most university professors are much better at deep dives into topics than they are presenting the basics.

[@stephenwalker700]

@@DaggerMan11 You must have been lucky enough to have good professors, I've found that most aren't and it's hard to find good explanations and presentations. Although guess that one all depends on who is teaching/presenting.

[@peterthegreat996]

Probably a US college - profits before people

[@kerysherbert8716]

You can literally hear that you are excited about what you're teaching which is (for me) contagious, and makes learning so much more enjoyable. This is great content and has been extremely useful. Thank you!

[@joschlohmann3272]

i agree hardly! it's so nice

[@johnferguson7463]

Best summary I have seen - where was this when I needed it 10 years ago - sooperb Dan

[@JFINZ889]

I have literally learned more in 3 minutes of this video than I learned in 2 weeks of my current application security course. How we process information certainly resides on the type of instructor. Thank you for the help! Much appreciated.

[@mxolisindlovu9194]

same here am new to Networks and i understand 100% better than all the University courses online. i want to be so good with networks practically and this guys is SIMPLY AMAZING!!

[@gusawa9868]

wow thank you sir for the very good video! understood the concept faster from here than from my professor!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@pareshparesh3361]

Sir, This is awsome presentation that reflects your sincereity to teach us who does not have a clue about it. Thank you for this detailed explanation. Salute!!!!

[@dhinakaranvenkatesan6586]

Your explanations are very clear ...even a 10 yrs old guy will understand....thanks for your demonstration

[@xunililak1674]

Wish I had ran across this video years ago and maybe I could have lit the fire that I now possess much sooner! NTL thankyou!

[@kodemasterx]

When you hear the excitement in a teacher's voice you can tell he is a good teacher... First time here, I dropped a sub and also thank very much for the slide.

[@jamesgiaquinto3907]

another one to remember is " People Design Networks To Send Packets Accuratly". Love your courses. You have a better way of explaining the technical side making it easy to understand.

[@L1011MD11]

So far the best concise OSI- TCP/IP layer explanation that easy on the brain cells.

[@suan1]

I've been trying to understand this for 4 days now, and I finally understood it from watching this 1 video. Thank you

[@lukasa6374]

Thank you so much for this! This was a fantastic overview of TCP/IP and OSI model. After falling behind and struggling to grasp these concepts as a whole, this helped tremendously!

[@josiah6328]

Great explanation, I really appreciate the time and thought that went into your presentation.

[@gnanajeyam6259]

From data -> Segments (With Port address information) -> Packets ( which adds the destination IP address) -> Frames -> ( which again adds the Mac address) and then to bits. Best video tutorial for osi model in the KZbin. We need more top quality videos from you dan.

[@zglitch4021]

Just completed the module for my college course for the OSI subject... Quite literally told me to read 10 page from a text book, go through one slide show and then take a test... lets just say the test didnt go so well. This video is amazing ! and I am surprised my college course did not have a video lecture on this complex system.

[@benrich5196]

By far the best and the most comprehensive and the most detailed explanation of the OSI model.

[@BilalHeuser1]

Thanks for this wonderful explanation of OSI and TCP-IP. :)

[@KhesrawIbrahimi]

Thanks it was really clear and informative For People from the North: To remember the OSI Model -- -- -- Please Drive North To See People's Awesomeness -- -- --

20 minutes and i am ready for tomorrow's exam. Appreciated♥️

[@mangeshhercule1193]

Excellent Teaching Sir, A great salute. From South India

[@AyseYilmaz-pm8ob]

It's very useful as you give an overview about all the terms by explaining the abbreviations that come up all the time when learning. Well done and good job:)

[@LisaMcGraw201]

This has been one of the best videos explaining TCP/IP from bits to data. Thank you so much for this video.

[@Yonisadam12]

the best explanation of ISO, which helped me in 20min even though I have been struggling year and half! thank u

[@AkilaAriyathilaka]

Your enthusiasm is palpable, and Thank you so very much fo this wonderful lecture. It was a treat to watch it. 20 minutes went by super fast lol

[@mohammadz1296]

KZbin recommended this video for me, when I saw the channel name I was like: OMG!!! it's been years (since 2013 i guess) since I started watching your videos and you were very helpful, thank you very much, much appreciated.

[@Oomtet]

wow i almost skipped this video i would have missed a great deal of knowledge, thank you sir..

[@cynthiacotton2399]

Thank you Dan for the information. It was totally thorough. I learned more in 5 mins than I have in a regular course. I needed a refresher since it had been a while since I had to use this and it was great! Great job and I love the enthusiasm you have with it. It makes others enthused as well.

[@sharissee5334]

You sharing your slide deck with us just makes this even more better than the presentation and explanations you gave!!!

[@gurkengerd9981]

Thanks for this summary. It really helps to see everything in a wider scope with less detail to get all the connections. Our professor only talks about 1 specific thing at a time and we have to do the connection on our own.

[@upzk7752]

A WOW!! summary 👌 Thankyou so much. I found this when i teach students, i wish if i found this when i was learning back in college. Then I could've raise my marks for sure..

[@kalyankonjeti977]

Thank you for the simplified explanation. I thought i need a day to get proper understanding but you have helped me to save my day ( - 20 mins) :-)

[@davidmckee533]

Dan is the man. He kicks complication in the buttocks and makes it simple. Thank you Dan!

[@salmankh100]

Very well explained in a short video. Appreciate your efforts.

[@rl1314]

Thank you! I'm a total newb trying to compete the Google IT cert for a tech support job I applied for and the Network stuff is not well explained and it's beena struggle. I've needed so many additional resources and explanations to get through it and this has really helped me a lot to put it all together as far as the layers and their specific protocols, etc. I'm going to check out your other videos on the network layers. Thank you!!

[@anweshabasak603]

Beautifully explained. I have watched multiple videos but this one gives the best information in less time.

[@chrisa703]

J'ai vu beaucoup de videos sur le sujet. Franchement celle ci exoliquer super bien le sujet. Félicitations !

[@Extravibes1]

Very clearly and nice explanation of each layer. Thank you for the share knowledge.

Good Luck on your interview!

[@hamzaamir3305]

how it went? :D lol

[@louiebee4345]

Aww thanks, y'all :) I did well, but none of the tcp-ip theories came up. It was for production engineering. Didn't make the final cut but im honestly happy to have made it that far. Looking forward for the next chance 👌

There's another one I use going down the OSI model: All People Seem To Need Data Processing. That's always worked for me.
