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?
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
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..
This is by far the best material that I ever saw explaining the basics so well. Thank you!
With my struggle of understanding many system/architectural concepts this channel is "more precious than gold and platinum"! 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...
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.
Watched the video twice, once for the content, once for the presentation ; that's some amazing skills in both that you've showed us !
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.👍
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.
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!
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.
This is one of the best way to explain OSI protocols.
Thank you. You are the best!
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.
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.
The use of visual, colors and movement all together is amazing. Very ADHD friendly! Thanks!
Yup. Helped me a lot.

The only way
I appreciate you for explaining in an ever-so-concise and easy-to-understand manner
Best animated video on youtube about OSI Model.
Came for the knowledge, stayed for the graphics! Excellent work, it kept my interest from beginning to end!
The session layer creates the setup, controls the connections, and ends the teardown, between two or more computers, which is called a "session".
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!
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.
Thank you for another fantastic and thought-provoking episode!
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!
Happy holidays everyone! Hope things get better for all in the new year.
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!
One more awesome educational video. I like Load balancer touch in the end. Good job.
Amazing video!! Really clarifies the whole model very well :)
I appreciate your efforts , graphic that you made cleared my questions .Thanks .
YESSS, my prayers were answered!! Y'all are awesome.
Great explanation, concise and to the point.
It would be useful to have the whole OSi model explained for those of us studying for the Network + I love the visualization.
And I finally understand these concepts. Thank you!!
Your work is awesome, loved yr passion and work, truly amazing, God bless you
Really well explained about the data transfer over OSI layers between two devices
I like your animated diagrams)
amazing videos and explanation. i think i have to start watching all your videos
Very detailed. Subscribed. Thank you.
YOU EXPLAINED THIS SO WELL THANKS!!!
Amazing explanation skills. You got a new follower
Amazing explanation. thank you
🥺🥺🥺🥺 your making contact is very understandable way thanks for this content ☺️
Most easy tutorial on OSI
This video helps me a lot. Thanks!
Is this the best complete educational video on youtube?
Great work!💯
Thank you for your amazing topics.
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.
This was very good.
Well explained - thank you!
really well explained. Thanks
Thank you. Well done and to the point.
These videos are incredible
Very well explained thank you
This video made me subscribe your channel. Thanks for the awesome content.
Thanks for creating this
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.
i love your videos. Thanks a lot
Always awesome on complicated topics!
Plz name the tool used for animations.
Amazing! Thank you.
Love this channel
So useful thank you!
Can you do video about QUIC in details and its advantage & disadvantage against TCP or UDP? Thanks!
Great video!
great video, thank you
Can you please make a video on how a SQL engine works?
This is better than $200 textbooks
Good one man!
from 7 back to 5 layers. I like it 💪
very detail, thanks
This is the best video exp ever..!!!
@ByteByteGo can u do a video on Concurrency?
Great videos! Love your channel! Did you use power point tool to create all these animated diagrams too! Thanks!
Great videos, can you do more on networking essentials.
Thank you! :)
Awesome!!!
Great video
Beautiful! What software do you use to create the animations and illustrations
Very interesting keeping Rocks
thank you!!! and contniue............
legendary video
I wish there was a guide on youtube that connected the layers to hardware because my class has been abstract and conceptual so far.
Great bro
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?
Thank you!
cute & helpful thank you ♥
Thanks!
Quality 👌
woa, thanks for great memory :D
ty so much!
Love it \o/ 💜
Thank you
whao - combining layer 4 to 7 - its probably a better idea if you go take a 4 semester CISCO training at a local city college, if you trully want to learn the 7 model
Good ❤
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?
🐞The preview image has the application layer twice.
could you go into detail differenciating l4 and l7 load balancer
Nice
Very informative videos, thank you. btw, do you have a Mastodon account ?
What tools are used to make the animation in the video
