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 UA-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.
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..
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
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.
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.
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!
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.
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!
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.
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!

This is by far the best material that I ever saw explaining the basics so well. Thank you!
The use of visual, colors and movement all together is amazing. Very ADHD friendly! Thanks!
Yup. Helped me a lot.

The only way
With my struggle of understanding many system/architectural concepts this channel is "more precious than gold and platinum"! Thanks a lot!
I have my College test for OSI Model tomorrow. I was looking for such a perfect explanation. Thanks a lot!
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
Just started Network Administration this semester and this video clarifies the OSI Model pretty well. Thank you.

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 needed a refresher on this and this is perfect. Really appreciate you laying it out visually. Thank you!
Happy holidays everyone! Hope things get better for all in the new year.
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.
Best animated video on youtube about OSI Model.
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.
Watched the video twice, once for the content, once for the presentation ; that's some amazing skills in both that you've showed us !
Honestly, the best explanation, visual as well as spoken I have ever seen. Great job 💪

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.
As a newly minted CS student (with an Associate degree), I learned something new but I was already subscribed 😭
Came for the knowledge, stayed for the graphics! Excellent work, it kept my interest from beginning to end!
I like your animated diagrams)
Well explained! Most best presentation ever.
The session layer creates the setup, controls the connections, and ends the teardown, between two or more computers, which is called a "session".
One more awesome educational video. I like Load balancer touch in the end. Good job.
This is one of the best way to explain OSI protocols.
Thank you. You are the best!
wow.. that was very clear explanation. I immediately understand how each layer works and used in operational perspective. Thank you for the video!

Most easy tutorial on OSI
amazing videos and explanation. i think i have to start watching all your videos
Your work is awesome, loved yr passion and work, truly amazing, God bless you
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
Great video, seeing how the data moves up and down the OSI model with a real world scenario really helped!
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!
Really well explained about the data transfer over OSI layers between two devices
Ive got an exam coming up im gonna use this as a guide
I appreciate your efforts , graphic that you made cleared my questions .Thanks .
Very detailed. Subscribed. Thank you.
YESSS, my prayers were answered!! Y'all are awesome.
And I finally understand these concepts. Thank you!!

Awesome explanation. Thanks
really well explained. Thanks
Is this the best complete educational video on youtube?
Amazing video!! Really clarifies the whole model very well :)
Thanks for creating this
❤❤ Thanks for the animation 😍😍
So useful thank you!
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.
It would be useful to have the whole OSi model explained for those of us studying for the Network + I love the visualization.
very detail, thanks
Thank you. Well done and to the point.
Love this channel
Thank you for your amazing topics.
Can you please make a video on how a SQL engine works?
Great work!💯
