I’m glad I came across your channel. I work for Amazon overnight and decided to apply for their seasonal/ IT Associate Specialist role and they scheduled an interview with me!! 8/22… I have worked in tech, but not on the IT side. I was a Transport, Switch, NOC, NCC & field tech for years, now my aspirations have shifted to data. I have wanting to learn and have tangible IT skills for years - so here I am, a mom, techie, student at 53 ready to challenge myself further. To whoever’s reading this: life is gonna happen, excuses will creep in, but show yourself that you’re bigger than your fears and/or excuses - you’re ready - take action.❤
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
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.
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!
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.
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!
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 remember OSI model like this way : A -> Applications Priest -> Presentations Saw -> Session Two -> Transport Nun -> Network Doing -> Data Pushups -> physical
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.
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 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 :)
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...
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
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!
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)

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!!!
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.
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.
@@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!
"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.
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.
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'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.
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.
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 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!
Absolutely blew this out of the park! The passion that a mere man can have on such a subject is breathtaking. Every moment of the episode is such a learning experience. One day I hope to be as learnt as you, my good friend. I'm not subscribed? let me fix that.
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!
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
-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 ... !!!
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.
8:03 i feel praised by that comment. Im currently 1 1/4 months into training for system integration and ccna is one of the things necessary. But i already learned so much stuff. I think i got 10% of my training down already. Im so good at this course and i already have the osi layers memorized with protocls like mac ip 1000basetx or udp tcp ftp http dhcp and dns. All names remembered. I feel like a god cuz my memories and learning skills are awful. I want to be a god in networking, system integration, setup and planning, programming and overall system management..
I have been studing networking for 5 years and I always had problems with the OSI model, but the "All People Seem To Need Data Processing" is the best thing I have ever learnt
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.
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.
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!
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.
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!
I like the way you explained these networking concepts. I would say that OSI Model is a theoretical model, and TCP/IP is practical implementation. TCP/IP is protocol stack and maps to directly to the OSI Model. Other protocol stacks include: Novell IPX/SPX, AppleTalk, and DecNET.
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
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"
I have a Beachelor degree in Computer Engineering, and you sir are explaining things a lot better than my professors at university did. I wish you had videos when i was in university. Kudos to you
Studying for my network plus. You are entertaining to watch, which is important for me since I tend to fall asleep throughout these courses. Too bad you didn't have a net+ course.
Here go my mnemonic for the OSI model. ================================== Application: A - A Presentation: P - Priest Session: S - Saw Transport: T - Two Network: N - Nuns Data Link: D - Doing Physical: P - Pushups
Chuck, I took a network course many years ago and I had no idea what instructor was talking about about layers, but somehow I watched 3 episodes of your CCNA video, somehow I can pickup what you said. Really appreciate your works.
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
Thank you, as someone coming from Comptia A+ the OSI model was very confusing. You have me wanting to research the history between the OSI and TCP/IP debate
All- application
People- presentation

also "Please Do Not Throw Sausage Pizza Away"
That is how I learned it last year when I did my first few CompTia certs

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
i am studding for my test next week on osi and i came to the best teacher, mr networkchuck
-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 ... !!!
I'm a Linux system administration and I just love your channel brother. Thank you ❤️
i love this guys , i got a full chap in this, now by watching it i understand everything. Hope to meet him one day.
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.
How can someone explain so well and make it fun, wtf!? 100% supporting you.
8:03 i feel praised by that comment. Im currently 1 1/4 months into training for system integration and ccna is one of the things necessary. But i already learned so much stuff. I think i got 10% of my training down already. Im so good at this course and i already have the osi layers memorized with protocls like mac ip 1000basetx or udp tcp ftp http dhcp and dns. All names remembered. I feel like a god cuz my memories and learning skills are awful. I want to be a god in networking, system integration, setup and planning, programming and overall system management..
I have been studing networking for 5 years and I always had problems with the OSI model, but the "All People Seem To Need Data Processing" is the best thing I have ever learnt
All people seem to need data processing!!! you took me back 16 years to my first tcp/ip class in college! :)
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.
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.
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.
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!
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.
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!!!!!
This guy is a living legend. I never loved networking like this before.
FINALLY, SOMEONE EXPLAINS WHY WE ARE STILL TALKING ABOUT OSI
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!
I like the way you explained these networking concepts.
I would say that OSI Model is a theoretical model, and TCP/IP is practical implementation. TCP/IP is protocol stack and maps to directly to the OSI Model. Other protocol stacks include: Novell IPX/SPX, AppleTalk, and DecNET.
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
I'm so glad my teacher uses your videos to teach us. You're super easy to understand and you keep my attention somehow.
Also I love your beard
The amount of knowledge your spitting is ridiculous. Love your channel and keep up the hard work!
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"
I have a Beachelor degree in Computer Engineering, and you sir are explaining things a lot better than my professors at university did. I wish you had videos when i was in university. Kudos to you
Studying for my network plus. You are entertaining to watch, which is important for me since I tend to fall asleep throughout these courses. Too bad you didn't have a net+ course.
Damm!!! This guy is a networking god and his teaching is very clear
Here go my mnemonic for the OSI model.
==================================
Application: A - A
Presentation: P - Priest
Session: S - Saw
Transport: T - Two
Network: N - Nuns
Data Link: D - Doing
Physical: P - Pushups
Chuck, I took a network course many years ago and I had no idea what instructor was talking about about layers, but somehow I watched 3 episodes of your CCNA video, somehow I can pickup what you said. Really appreciate your works.
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
I had a teacher who used the mnemonic device: American Pigeons Soaring Together Neatly Dropping poop. Yours is a little easier to remember...
This is 2023 I am glad I found ittttt so well explained, thank you very much
I wish I had you in School!! Your method of teaching is awesome!
I remember osi model as " Apset N Dp "
a-application
p-presentation
se-session
t-transport
n-network
D-data Link
p-physical
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
This is honestly one of the best tutorials I've seen
OSI Model from Bottom to Top : (P)lease (D)o (N)ot (T)hrow (S)alami (P)izza (A)way. Thats how i learned it :-)
Same, except my instructor used Sausage instead of Salami.
Your way of teaching makes this difficult information very easy. all the respect and the Grateful to you
Thank you, as someone coming from Comptia A+ the OSI model was very confusing. You have me wanting to research the history between the OSI and TCP/IP debate
