Honestly, that's the best one I've seen. I put it on my midterm study guide lol
WOW..... That's a good way to remember that!
Thank you legitimately
Yo!
Going through this series wanting to make a career change. You're an awesome teacher. You probably won't see this but you definitely are doing amazing work. Thank you for taking the time to help us all out
Did you make your career change? Are you still learning? Have you landed a job or still looking? Have you given up and moved on?
@@siberwolf33 😂 Like to know as well haha
@siberwolf33 did you?🤓
Need an update
haha
Dude i cant explain how much i am thankful for this series!
I remember the first letters of the OSI model with the phrase “A Priest Saw Two Nuns Doing Pushups”
Or like I learned in college, while going in reverse, "Please do not throw sausage pizza away."
Mine was---- please do not think sex proves all
All people seem to need Dominos pizza
@@elihau2454 Pizza being my favorite food, that's one I could easily get on board with!
All People Sleeping Through Networking Don't Pass seems to do it for me and all my students. Where did I learn this one? From our legend: David Bombal!
I never knew how much I wanted to learn 10-20 minutes at a time every few days.
I just finished my Bachelor's Degree in IT and I am now studying for CCNA. Your videos are way more enjoyable than being glued to a book non-stop. Thank you for your effort in making these videos. Well done!
I love that Guy, his Mindset is pure motivation to start from scratch ! 🧔🧠❤
These classes are more entertaining, digestible, and helpful than all of the the courses I've paid for. I feel like they just teach me about it and you somehow make me love it.
I always remembered it as: "Please Do Not Throw Sausage Pizza Away" I remember it from when I first learned the OSI years ago!
also "Please Do Not Throw Sausage Pizza Away"
That is how I learned it last year when I did my first few CompTia certs
I could hear the same concept 50 times, but when Chuck begins to describe the concepts, it just makes sense! Thank you for all you do. :)
Worked in IT for about 3 years now. Watched your "Starting over in IT" video a few days ago. Passed my AWS CCP but feel like I need better fundamentals in networking! Currently studying for my Network +. Love your channel and all your content. Thanks for bringing a modern and fun take on reaching networking. Graduated from college last December and my networking book was from 1997 and came with a floppy disk... needless to say we did not get taught very well!
Ty chuck. Went to school for ccna 2017-2818,had kids now back trying to complete my ccna. Your videos are awesome and explain it much better than most. Analogies etc make it easy to understand.
Really appreciate all of the effort you put into your videos Chuck. You inspire me to be a better teacher in my own!
Thank you Chuck! You have no idea how much this has helped me. I learn a little differently, and have a very clear representation on these subjects makes me feel that much more confident! Thank you, thank you!
I've been struggling to choke down the OSI model for years. I have my Network+ in a couple weeks and FINALLY get it. Thank you for making this so relatable.
You've made me love CCNA from the first episode and for that I wanna say thank you. Your explanation of things is marvelous. God bless you
Chuck,
I just discovered you. Completely rekindled my love for programming/ethical hacking/ etc. Thank you, thank you, THANK YOU!
When I first was studying networking in the mid 2000s I was taught the OSI model . To my understanding the TCP/IP model is the same except it merges the layers of the osi model so there are less in total. I find using the osi model great for troubleshooting as I feel I can see more and break things down more finely.
This is how modern teachers do, they simplify every point smoothly like you. You are the BEST undoubtedly Chuck!
Man, your explanations are so enthusiastic and straight to the point, I love it.
I have to study cisco as part of my it career switch pack, but when I was watching the videos I couldn't understand anything and just wanted to skip to the next and so on.
I am really happy I have found this content
Love from india man. I am network administrator in infosys. I watch your videos regularly.make more like this.really helpful content❤
Chuck I obtained my CCNA 1 week ago, thanks for all your great content and motivation!
While studying for my network course at the Uni specifically Layers (OSI and TCP/IP), this video notification came to me! Just in TIME! Thanks! Saved me a lot of time
This course is much needed for me. You are a blessing! Thank you so much . I just wish you never stop making such cool videos .

I can't wait to see subnetting episode that give headache x_x
Same! Subnets and Subnet masks are interesting and a bit confusing to me :D
1000100000100100000100100...
Binary method, my dude!
Bro it is very easy to understand no such headache thing☺️
No way)))
We just got to the OSI and TCP/IP models in my intro to networking class. This video was immensely helpful, thank you Chuck!
Where were you back in the days when I was trying to wrap my head around the OSI-model? This was brilliantly explained! Awesome!
Have an internett point. You deserved it.
I am a computer engineer by profession, and I hold an Engineering degree, but damn, OSI Model just became clear to me now. For the life of me, all through my undergrad days and then 14 years of industry experience, I was like how the hell do you map these models practically. Finally, I have my answer :)
The Indian education system in a nutshell :(
Surely.. There is only coffee in your Veins.. 😅
Great Content Keith Chuck.. Loved it.. Thanks for all the efforts you are putting in for this...
Networking is amazing, every time I think about the internet and how all devices are connected it blows my mind, it seems surreal to me.
Oh. My. God. I got my CCNA certificate end of December, but i think that was out of luck because I have to relearn it all (it was very clear). I'm SO SO happy to have found you and SO SO sad I didn't find you whilst studying my CCNA. I'm binging your videos this weekend. You are the teacher we all need. You explain things in such a good and easy way.. i mean, dayum. THANK YOU !
I'm in love with this series. You always answer the right questions.
I second this comment! So true Chuck is an awesome teacher!
Damn, my attention is so easily distracted.
This shirt got my attention!
Haha, the shirts serve a purpose
It probably the 5G from your internet
@@NetworkChuck Is it a Ron Swanson inspired t-shirt?? Seems like it but I can't be sure haha. Your videos are awesome btw. For the mnemonic phrase for me it's A Priest Saw Two Nuns Doing Pushups. It stayed because I find it funny and uncommon!
Just started this journey a little later in life than I wanted. I really appreciate your videos and look forward to taking the CCNA now instead of dreading it.
I am definitely learning! Thanks a million for this course. You have demystified for me these layers, never quite got the hang of it till watching your tutorials.
Excellent Chuck!! Thank you for your efforts.
Thanks man. Love the history lesson in the beginning, because we need to know how things got started.
Love how I’m looking at ccna content for my A+ but you’re making learning it fun thanks
Have been in IT for just about 4 years now. I have my Sec+ and A+ but still no networking certifications. So far this is all stuff I know, but I'm eating it up as review, and clarification for things I didnt fully understand before.
Very good content.
Thank you so much sir for Your Support Appreciate a Lot 👨🔧
OSI was around a long time; technically, each vendor followed the model when they created their proprietary stacks. OSI was too vague, allowing vendors implement it in very different, incompatible ways. TCP/IP is a well defined protocol, very clear on layer boundaries and packet formats. Unfortunately, TCP/IP was designed with the mindset that every computer on the network is trusted. That's why it's a never ending struggling to secure things. DNS is fairly vulnerable, POP mail was a joke, and so was telnet (remote shell). Everything was in clear text on the network, no encryption or protection from DNS poisoning or spoofing. Things are much better, but still far from perfect.
I signed up with htb and I am so humbled … I know nothing…but my brain is reviving and now want to learn !! Thanks Charles
man this guy is such a good storyteller...Im an EE studying Linux and ended up in this channel, few videos later, im now studying for a test i didnt even knew existed until now
1. Please
2. Do
3. Not
4. Teach
5. Students
6. Pointless
7. Acronyms
Would fit best, I think!
Hey Chuck! Your content is amazing! Thank you for commitment!!!
I miss Layer 8, somhow you forgot it ;P
The worst layer of them all.
One to master them all
Chuck, you are AMAZING! Thank you so much for this series! Thoroughly enjoying it!
I didn't know what moment I went through all the vid!! it's just so good that I dive so deep into it and enjoy it so much that it finished too fast.
Please do not throw saucage pizza away......this will be better to remember the layers in OSI model
This OSI mnemonic got me through school:
A ss
P resents
S eriously
T roublesome
N dications.
D ont
P lay.
i love the storytelling and history about IT stuff in every episode it is easier to remember but it nice to know why and when to better understand
Im studying PLC programming for controls automation for my job and other than running applications, i have very little knowledge of computer science. Your videos are extgremely helpful! thank you so much for your time and knowledge! thanks!
I am second viewer❤

i'm very lucky to found this channel with this kind of content. keep it up budd, you are helping people out
How can someone explain so well and make it fun, wtf!? 100% supporting you.
Wow honestly I am so happy I found your channel. My prof is simply reading off the powerpoint and not explaining a single term. Thanks for facilitating my learning and doing his job lol
This is honestly one of the best tutorials I've seen
This is one of the best content i watched for years. Thank you !
My dude, I’m learning so much from this series. Thank you so much for these videos. I came in two days ago barely understanding networking and already feel much more comfortable studying for the CCNA exam! Also, thanks to another of your videos I’ve started applying for a few help desk positions to get my feet wet in tech. You’re awesome!
Any luck?
Your tutorials along with Farhouzen are helping me a lot to clear the concepts.Thank you sir 🙂
Excellent stuff! Good for you, bud, taking the time and doing it right! Great job!
I'm a Linux system administration and I just love your channel brother. Thank you ❤️
-Hi, thanks for taking this free course ... !!!
-I started as an electronics and automation technician and evolved into IT in my career where I took care of the Data Center of the Control Tower of the largest airport in the south emisferio, as well as the radios, radars and windows and Linux servers and the network there for almost 20 years, and now living here in Brazil I am stopping to immigrate to Canada.
-It's funny how things have evolved and in 2010 when I started creating servers to monitor the networks of different systems via SNMP and map them in Nagios at the time I needed two Xeon servers one with Nagios and the other with databases, and several desktops as probes of the networks I monitored, apart from Arduinos with NICs that I programmed to read the status LEDs of the equipment and the servers outside temperature and energy and send it all to the SNMP Nagios server that I did on Linux at the time.
-It's ridiculous to see that nowadays there are complete servers \ probes on a Raspberry Pi with NEMS Linux running on it, imagine in 10 years we changed two Xeon servers that cost 100 times more than a Raspberry 40 dollars to do the same function, which great for NOC Eng. how we can work and improve.
-Thanks to god, the standards allowed this evolution of technologies.
-As for the fight between the OSI and TCP / IP models for the new standard that Cisco adopted they simply made it official what they already did, in the Packet Tracer themselves they kind of played the upper layers in one, which is where the developers work , and it's even how companies work by dividing the professionals from the layers below and those from above.
-Now who works with the most basic programming as in Arduino or the new devices like it, where the well cross protocols programmed in C ++ or in IOT devices need the differentiation of the layers above.
-As well as a Good NOC Engineer knowing better what happens in the highest layers, you can discuss better with an analyst who for example may have programmed your application imagining infinite band or a security specialist who will work with Firewalls needs to know the layers above better and subdivided, or better understand the Headers of your traffickers to do a better trobleshooting, ok, but the vast majority of NOCs do not simply classify the problems as Layer 7, now 5.
-I still think about OSI, because it was as I learned but I understand why they changed the model for the test.
-Now studying for certifications I realize that much of the knowledge I had at the time was self-taught but things were always lacking that when I study for CCNA I realize that things were missing, and now I decided to take both my CCNA the CompTia Linux + and the certification of VMware and CCNP Data Center in a few years.
-Alias now that the microsoft System has Linux incorporated, will the CompTia and LPIC certifications be separated due to these new paths that microsoft wants to follow ...?
-Which of the two certifications is better in my case CompTia Linux + or LPIC-1 ...?
-Thanks for the videos please continue you and David ... !!!
Thank for these. I'm just starting out and the OSI and TCP/IP models are very overwhelming; you do a great job of breaking up the layers and concepts.
You're awesome man, thank you for all your context. My professor said he disliked something about you and my whole entire class and I got at him! lol You're supported man!
cool guy!!! easy to understand... i took CCNA modules 8 years ago... i need refresher, and im so lucky to find your channel.... youre awesome!!!!!
Thanks for these courses, I know others put stuff out but I think you're a really great teacher! You have a very engaging, and approachable personality. I'm sure I'll need a couple more study resources than just this playlist, but it's a great start for me. Can't wait to get through it all and upgrade my career.
Love your personality and the simplicity of your explanation. Thanks Chuck!
You are amazing! I adore to watch your videos. Thank you very much for everything what you do for us!
Chuck, really appreciate your delivery of this content, you make it very easy to understand thank you!
You're awesome man! Just found this channel. Love the info and your enthusiasm/voice
Hi, Chuck! Thank you for sharing this course content, for free! I'm a programmer at heart, but I'm wanting to shift my career in IT, and these videos helped a lot. Amazing work!
OMG Chuck you have saved the day for me man. I was struggling to relate to the traditional tutor and there came your video so I thought why not give it a go.
So easy to understand and relate to a fellow gamer.
Thank you so much.
I swear I smiled the entire time watching this video! You made it so easy to understand, thanks
These videos are golden. Thank you for being a super entertaining teacher!!
I'm not even studying for a CCNA Cert but these videos are just so interesting! Thank you!
I love this guy how he explain. The Best channel ever...
you rock chuck! yes you rock! the way you are teaching is straight injecting in my mind! your the best I have learned a lot from you. Thanks keep up the good work brother
I want to learn more about network and I think it's so hard, but I think now I'm in love with it . I'm thankful to you thanks for your effort. I really do enjoy watching your videos.
I have never heard someone explaining the TCP/IP so easily wow 🤩
Thank you for always giving me the perfect answers to my questions!!
This guy is a living legend. I never loved networking like this before.
I'm not even trying to get a CCNA.
(Just trying to start home labbing, and was confused by Network terms, and why everyone mentioned unify gear 😂) but WOW am I loving this series. No one, no article, no how-to, and no video has ever explained networking in such a clear, concise... entertaining, and helpful way.
I highly reccomend you mention your own series anytime you do future content on server's, Nas setup, homelab updates, etc.
Because I know I'm not the only one who got interested in setting up a NAS/homelab and got confused by a rabbit hole of networking terms they didn't know.
Such easy to understand explanations. Thanks!
Currently doing the Google IT cert as a refresher. Hoping to continue on to CompTIA A+ and maybe CCNA after that. Trying to absorb as much as possible!
Toujours aussi bien expliqué. Vivement les prochaines vidéos
There is one person named MOHAN in India, Bengaluru. I can proudly say that nobody else can explains TCP/IP and OSI like him. I'm in Juniper networks right now as a protocol test engg. He just changed my life!
My first professional assignment was connecting Unix apps with mainframe apps. Getting APPC over LU6.2 over VTAM over SDLC over a trunk line was the hardest part.
In the middle I used an IBM PS2 MCA box running Comm Manager on OS2 warp.
Great course, can't wait to dig deeper.
Also, this guy shirts!!
I LOVE THIS COURSE JUST BECAUSE OF YOU! THANKS!
The amount of knowledge your spitting is ridiculous. Love your channel and keep up the hard work!
All people seem to need data processing!!! you took me back 16 years to my first tcp/ip class in college! :)
I can't help noticing that we have the same keyboard and desk mat....also, Im just jumping into IT and came to these videos after reading my textbook twice and needing it made simple for me. Thank you for this video series!
This guy is my favorite person on the internet right now.
Chuck thank you so much for these lessons they are extremely appreciate it!!!!
These videos are going to explodeeeee!!! Best teacher ever!!!!
"Please Do Not Throw Sausage Pizza Away"
And you said it just after I pause the video to reply. I really enjoy your videos Chuck. Keep up the good work.
I'm 59 and just started doing cyber security management course at University online. I really enjoyed your videos and have been able to use them to help students learn about the concepts and network fundamentals.
dude! thanks man for making this dummie friendly,,, ive been watching videos for hours and got nothing. Subscribed (Y)
👌 perfect 👌, keep going bro.
Explained in a simple n perfect way.Thanks for your time n efforts.
You are so real into your explanations💃🏾💃🏾💃🏾it’s like fun👌
