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
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!
Dude i cant explain how much i am thankful for this series!
I never knew how much I wanted to learn 10-20 minutes at a time every few days.
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 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!
This is how modern teachers do, they simplify every point smoothly like you. You are the BEST undoubtedly Chuck!
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.
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.
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
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!
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.
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

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)))
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 .
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.
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 :(
I'm in love with this series. You always answer the right questions.
I second this comment! So true Chuck is an awesome teacher!
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
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...
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!
We just got to the OSI and TCP/IP models in my intro to networking class. This video was immensely helpful, thank you Chuck!
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.
Thanks man. Love the history lesson in the beginning, because we need to know how things got started.
Excellent Chuck!! Thank you for your efforts.
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
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.
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.
Thank you so much sir for Your Support Appreciate a Lot 👨🔧
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 !
This guy is my favorite person on the internet right 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
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.
Love how I’m looking at ccna content for my A+ but you’re making learning it fun thanks
Please do not throw saucage pizza away......this will be better to remember the layers in OSI model
Please Do Not Take Sales People Advice - Physical Data-Link Network Transport Session Presentation Application
dude! thanks man for making this dummie friendly,,, ive been watching videos for hours and got nothing. Subscribed (Y)
Chuck, you are AMAZING! Thank you so much for this series! Thoroughly enjoying it!
I am second viewer❤
This OSI mnemonic got me through school:
A ss
P resents
S eriously
T roublesome
N dications.
D ont
P lay.
This is honestly one of the best tutorials I've seen
FINALLY, SOMEONE EXPLAINS WHY WE ARE STILL TALKING ABOUT OSI
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!
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?
How can someone explain so well and make it fun, wtf!? 100% supporting you.
I'm a Linux system administration and I just love your channel brother. Thank you ❤️
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.
I took the 1st letters and say them all as 1 word PDNTSPA, saved me in networking exams :)
Currently working at an MSP and have NOC interviews coming up. This video was a good and entertaining refresher.
Not sure how important this comment will be but 5:30 is what made me watch all prior videos. I originally was only here for OSI and TCP/IP learning.
-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 ... !!!
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
In Germany we're memorizing OSI by "Alle Priester Saufen Tequila Nach Der Predigt" which is translated to "All priests are drinking tequila after the sermon" lol
I've been a customer of Boson for years on CCNA/CCNP/CCIE , it's good and accurate. alltho expensive but a good investment as an assesment tool before you sit an exam cuz that's more costly if you fail it.
Your tutorials along with Farhouzen are helping me a lot to clear the concepts.Thank you sir 🙂
i'm very lucky to found this channel with this kind of content. keep it up budd, you are helping people out
This is one of the best content i watched for years. Thank you !
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!
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!
I was in the process of doing courses 10 years ago to become a network engineer, but I dropped out and decided to become a pilot instead - big mistake.. I hate it.
You've re-sparked my interest and love of computers again...
I find it easy to memorize when using this mnemonic "Please Do Not Throw Sausage Pizza Away" this is for the OSI, when comparing it to the TCP you could imagine that you threw the sausage pizza away because it doesn't have the Transport and the Session layers.
Layer 7 - Application (Data)
Layer 6 - Presentation (Data)
Layer 5 - Session (Data)
Layer 4 - Transport (Segments/Datagrams)
Layer 3 - Network (Packets)
Layer 2 - Data Link (Frames)
Layer 1 - Physical (Bits)
I heard someone remember the OSI model from layer 1-7 with:
"Please Do Not Teach Students Pointless Abbreviations"
Damm!!! This guy is a networking god and his teaching is very clear
It's funny how I watched this dude talk about IT in my free time after school without me needing to know this stuff. Now I am in collage I actually need to know this stuff.
This guy is a living legend. I never loved networking like this before.
You are amazing! I adore to watch your videos. Thank you very much for everything what you do for us!
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!
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.
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.
I love this guy how he explain. The Best channel ever...
Excellent stuff! Good for you, bud, taking the time and doing it right! Great job!
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.
I have never heard someone explaining the TCP/IP so easily wow 🤩
Chuck, really appreciate your delivery of this content, you make it very easy to understand thank you!
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!!!!!
Toujours aussi bien expliqué. Vivement les prochaines vidéos
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 wish I had you in School!! Your method of teaching is awesome!
I should have finished my ccna im going to school currently to be an electrician. I also took plc and instrumentation. I think having a ccna, electrician license , plc all complement each other you may think I’m crazy but look at where technology is going.
Love your personality and the simplicity of your explanation. Thanks Chuck!
These videos are golden. Thank you for being a super entertaining teacher!!
When I was studying for my CompTia certs, I learned the OSI model from 1 to 7 as this :
Away
Pizza
Sausage
Throw
Not
Do
Please
Please Do Not Throw Sausage Pizza Away - Physical Data Network Transport Session Presentation Application
When trying to determine the best way to remember TCI/IP, still going from bottom to stop , I came up with with -
About
Talk
Not
Do
Please
Please Do Not Talk About (the OSI Model)
Your a great teachers Chucks, your illustrations are bomb. it only take a dumb ass not to understand after learning from you. You just increased my passion for IT, you came my rescue at the right time, almost getting discouraged and BOOM i found your page. thanks for all you do
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!
"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.
I remember first starting out in IT and we were converting from a combination of 4meg and 16meg Token ring to 10meg Ethernet. We clearly labeled ports that were 4 and 16 on the existing token networks, but because you had to get into the network card's BIOS on boot, kind of like how you have to do when getting into your PC BIOS menu, the rings would get beaconed and taken down often. Think about it. You move a PC from building A on a 16 meg ring and move it to building B on a 4 meg ring and forget to CTRL+A or whatever it was to get into the Token Ring NIC's boot settings and boom! That segment just went down. Nope, don't miss that at all.
