I’m still so confused by it like idk I’ve been reading for days about it and i just can’t grasp what it really even is but this is my first time taking a network course so maybe I just need to give it time
You're probable a lot like me. I need examples and real world applications in order to conceptualize these concepts. Just do a little digging and watch some TH-cam videos too. That may help.@@kayliejoye5158
@@kayliejoye5158 yeah it’s a little weird. lots of “actions” go on to send something from one device to another, and the OSI model is a convenient way of separating/organizing all these processes/protocols into a specific “layer” that contains similar protocols. For example, you’re usually using either UDP or TCP, not both. They both want to be given an http request with data, so they’re in the same layer 4. The osi model categorizes all the protocols that determine how you wrap up/encapsulate a bit of data so it can be sent from one device on a network to another, then “unwrap” it until it’s back to being useable data again.
Ask gpt. These are just the protocols computers follow. Depending on your level, understanding what each "layer" does. Or understanding why it's done should be enough
OSI = open systems interconnection Application protocol (Application layer + Presentation layer + Session layer): HTTP Transport layer: TCP (Sequence and checksum), UDP Network layer: IP Data Link layer: MAC Physical layer: Bits
I wish this channel had existed 15 years ago when I entered the industry. This is so good. (not just this video...) Of course, after 15 years, one understands more nuances.
First commenter here. I'm on youtube from 2008. Always wanted to do this specific video to teach this very basics of computer networking concept.. because I have taught this to countless people and engineers of varied fields since this is required for electric/electronics/software engineers alike.. I couldn't have done it better than you! Thank you & lots of love from India. 🔥❤️
Happy to hear you r here since 2008 .. Sir hows UVCE ?? Now ht are u doing Sir .. I'm currently studying at BIT College.. AI branch first sem just a month happend ... Pls tell me how to make studies better becoz I'm frm PCMBio background I m feeling tough to learn Computer related Subs ..couldn't get everything taught in cls ..pls guide me sir❤❤❤
@@raghvendrapotul590 Bro, don't worry. Everyone feels difficult to learn computer science subjects at first.. i was also from pcmb background. even i was feeling like vomitting looking at C programming language at first.. pls use youtube to learn basics and then you will slowly start liking Programming.. good thing is, programming is mostly all about logic.. you don't need mathematics..
I used to thought that each layer happen sequentially and independently which never really understood completely, but as he explain that it is just a 'framework' to describe real network system usefully. It got clear that each layer coexist and cannot be separated. It is not that the packet only need transport layer (e.g: for transmission between routers, i thought router is 'exclusively a "transport" entity'). Thank you so much, you may not aware how you help us get this priceless clarity.
I don't understand why this topic has been so complicated to me to memorize. Despite the wonderful animation, I still feel lost remembering every aspect of each layer. Thanks for the material!
This thing I didn't understand much in the college especially the practical part, but thanks to you for explaining in simple manner along with the animated diagrams.👍
very good explanation. Have learned it many times over the years, but always revisit it. This was a nice and helpful overview. Better than the ones I've seen in the past.
Thank you so much for your explanation at 2:27. The way I like to learn things is based on their function in an overarching system, so layers 5-7 have been confusing to me since they seemed too abstract to really understand without unifying them conceptually. Compared to the other layers, it really feels like differentiating layers 5-7 is splitting hairs.
You are very correct. When I started reading the ccna book 23 years ago, I had a really hard time accepting the many liars, especially the top 3 layer. Then I read the TCP IP model and it made more sense so you are correct. However, it is important to differentiate between tcp and udp by saying tcp needs a connection established first whereas udp does and just shoots away the packets.
Thanks for the easy-to-understand explanation. I'm taking a cloud certification exam soon and they don't give you much context for these layers in the material I'm using, so it helps a lot!
For "MAC addresses" part, could've been more useful to newcomers to show how peeling and layering repeats till the destination is reached. Still great job condensing this stuff with all the beautiful animations.
I map the 5th (session layer) into 4th layer. It suits better with the presence of TLS. 6th and 7th layer can be mapped to 5-layer Hybrid model presented in Andrew S. Tanenbaum book 'Computer Networks' 3rd edition, back in 1996. By the way, thanks for visual explanation.
Thanks for this video a question! As it goes through the network through each hop does the MAC address source and destination change for example. COMPUTER A (MAC ADDRESS OF computer A and Router 1)-> router 1(MAC ADDRESS OF router 1 AND ROUTER 2) -> router 2 (MAC ADDRESS OF ROUTER 2 and COMPUTER B)-> COMPUTER B? Also on Transport layer you said this is when segments are numbered Does this mean at this point the data has been broken down to small sections?
Hello, can you help me with this question, thank you 🙏🙏🙏 A printer that is connected in the network and other computers can see this printer, which one of the osi model layer works?
As a programmer for more than 5 years, I have never really understood the OSI Model, but after watching this, it clicks in my mind! Perfect!

With my struggle of understanding many system/architectural concepts this channel is "more precious than gold and platinum"! Thanks a lot!
This is by far the best material that I ever saw explaining the basics so well. Thank you!
I wish this channel had existed 15 years ago when I entered the industry. This is so good. (not just this video...)
Of course, after 15 years, one understands more nuances.
The use of visual, colors and movement all together is amazing. Very ADHD friendly! Thanks!
Yup. Helped me a lot.

The session layer creates the setup, controls the connections, and ends the teardown, between two or more computers, which is called a "session".
Just started Network Administration this semester and this video clarifies the OSI Model pretty well. Thank you.

Best animated video on youtube about OSI Model.
Watched the video twice, once for the content, once for the presentation ; that's some amazing skills in both that you've showed us !
I don't understand why this topic has been so complicated to me to memorize. Despite the wonderful animation, I still feel lost remembering every aspect of each layer. Thanks for the material!
I have my College test for OSI Model tomorrow. I was looking for such a perfect explanation. Thanks a lot!
This is the best explanation I have ever heard of OSI model.
Back in the college, I always struggled with this thing...
probably because the college teacher was not qualified to explain lol... and made things up.
This thing I didn't understand much in the college especially the practical part, but thanks to you for explaining in simple manner along with the animated diagrams.👍
I’ve got a test in 4 hours lol
How did you do on the test?
Me too bro
Me too
Did you pass your test?
same
very good explanation. Have learned it many times over the years, but always revisit it. This was a nice and helpful overview. Better than the ones I've seen in the past.
I needed a refresher on this and this is perfect. Really appreciate you laying it out visually. Thank you!
Concise and practical explanation of OSI. With a bit of web development experience, this is very easy to follow !
Wonderful, finally it make sense. Thank you Mate!
Like in schools, we literally study things which never come across in real life or taught correctly.
This is one of the best way to explain OSI protocols.
Thank you. You are the best!
Came for the knowledge, stayed for the graphics! Excellent work, it kept my interest from beginning to end!
wow.. that was very clear explanation. I immediately understand how each layer works and used in operational perspective. Thank you for the video!
Honestly, the best explanation, visual as well as spoken I have ever seen. Great job 💪
Great video, seeing how the data moves up and down the OSI model with a real world scenario really helped!
One more awesome educational video. I like Load balancer touch in the end. Good job.

Bro what u just did there wasnt just recording a video !!! u saved my life , thanks for that exact explanation that i was looking for
YESSS, my prayers were answered!! Y'all are awesome.
This really helped me to review what I learned at college. Very good video
I like your animated diagrams)

I appreciate you for explaining in an ever-so-concise and easy-to-understand manner
I appreciate your efforts , graphic that you made cleared my questions .Thanks .
This is one of the best videos I've seen regarding this topic. Simple and practical. Love all your videos, thank you for the knowledge.
🥺🥺🥺🥺 your making contact is very understandable way thanks for this content ☺️
Really well explained about the data transfer over OSI layers between two devices
Your work is awesome, loved yr passion and work, truly amazing, God bless you
Thank you for another fantastic and thought-provoking episode!
amazing videos and explanation. i think i have to start watching all your videos
For "MAC addresses" part, could've been more useful to newcomers to show how peeling and layering repeats till the destination is reached. Still great job condensing this stuff with all the beautiful animations.
Great explanation, concise and to the point.
Ive got an exam coming up im gonna use this as a guide
And I finally understand these concepts. Thank you!!
Well explained! Most best presentation ever.
Is this the best complete educational video on youtube?
Very detailed. Subscribed. Thank you.
Amazing explanation skills. You got a new follower
from 7 back to 5 layers. I like it 💪
very clear and concise explanation, thank you!
YOU EXPLAINED THIS SO WELL THANKS!!!
Amazing video!! Really clarifies the whole model very well :)
Amazing explanation. thank you
amazing video, i understood it perfectly thanks to you sir
It would be useful to have the whole OSi model explained for those of us studying for the Network + I love the visualization.
Best explanation I've seen. Thanks :)
Always awesome on complicated topics!
Plz name the tool used for animations.
Can you please make a video on how a SQL engine works?
Most easy tutorial on OSI
