how the OSI model works on YouTube (Application and Transport Layers) // FREE CCNA // EP 5

Well explained. Just enjoyed this. Keep the great work you're doing.

wonderful explanation bro, thanks

What does a network chuck do? The networkchuck is a medium sized tech. It is related to the network squirrel and marmot. It is known for its port sniffing ability, which allows it to navigate an extensive network of tunnels and burrows beneath open system interconnect fields and meadows.

im very thankfull for you ❤❤❤

Thank you so much for this information and FREE course. I'm prepping to take the exam in Dec. I'm currently working as a Network Operations Technician and your videos make everything I'm doing make sense.

Network chuck is legend.

You're subscribers should be at least like a 100m sheeesh!

BEST VIDEO TO LEARN OSI ! YOU ARE. BEST!!!

Good video.

Amazing teacher, thanks for this video!

thank you master

I'm having fun, thank you!

You are the best teacher I have ever seen in my life <3 but I do not know english, thank you google translator

🤩 i like your videos am called cyber from uganda

Great content !

Thank you for the video! I have a question though if anybody can help me. I don't really understand how the session layer can hold the connection without going through the lower layers. In order to establish the connection we need to send a request, don't we. If so, then how can we keep the connection in the session without reaching the physical layer?

Networkchuck this is excellent thanks

I appreciate you, Bro. You make learning IT exciting, addictive, and easier.

your videos very funny 😅😅

I have tried a few times to start CCNA study and every time I got bored out of my mind or bogged down within a couple of hours. This course and your teaching method has turned that around for me! This is excellently presented, the best course experience I have had. I am actually excited to learn Networking and have fun with each and every video! Great job and thank you!

tfw due to extreme boredom you let NetworkChuck teach you a rather valuble IT cert.

I know I am late to this, but I had a networking teacher give me and my classmates, over a decade ago, a way to NEVER forget how to remember this OSI model. She gave us pizza one day and left the room, came back grabbed an empty pizza box and slammed it to the ground while yelling "Please Do Not Throw Sausage Pizza Away"! If you noticed the acronym PDNTSP is the 7 OSI layers... Physical, Data Link, Network, Transport, Session, Presentation and Application. Even though I just dabble in networking on occasion, I will NEVER forget the OSI layers because of this action. Just a funny little story I thought to pass on.

Gracias Chuck, estoy estudiando con los libros de Wendell Odon pero ver tus videos me mantiene motivado cuando no tengo ganas de leer la teoría. Definitivamente voy a invertir en tus patrocinadores. Gracias Boson por patrocinar este video.

"socks proxy" is my favorite thing so far

You are a legend Chuck.

i think i learned more about networking watching your ccna series, then when i took my network essentials class and its because the way classes our taught which is usually by reading a textbook. just literally bore's the shit out of me! where i always end up falling asleep. i rather have everything straight to the point as well as simple explanations if i do have to read something.
