How the OSI Model Works | Network Fundamentals Part 3
The OSI Model Explained

Surely you've heard about the #OSI model. That's why you're here right?

Well, this is the right place for you! In this video we discuss models, and why they're used. We look into the physical, data link, network, transport, session, presentation, and application layers, and how they relate to the real world.

And finally, we look at an example. This shows how a web request flows through each of the layers.

For further study, I recommend:

THIS is just a goldmind. When ppl say "yea, jus go watch youtube." they talking about watch these kinda guys,

My guesses on the 11:59 quiz:
TCP/IP applications (Protocols): FTP(File Transfer Protocol), SMTP(Simple Mail Transfer Protocol), Telnet - Application layer;
JPEG, MPEG, TIFF, GIF - Presentation layer;
Service request, Session Control Protocol (SCP) - Session layer;
Flow Control - Transport layer;

Application layer: End-user services like web browsing and file transfer
Transport layer: checks and fixes errors, then delivers data error-free
Network layer: routers work at this level, and decide how and where traffic is forwarded along a path
Physical layer: Hardware for sending/receiving data on a medium
hope I didn't misunderstand something, if did please correct me.

My answer is:
The transport layer is responsible for the ports, which manage the flow of data going through the ports. If an application is using too much bandwidth, we can control its data flow in this layer without having to interrupt its process in the application layer.

The art of teaching is a science craft that only a few have mastered. You are one of them. I have been watching your videos for hours, one video after the other. Gosh, they are brilliant. The words are very descriptive in the simplest of languages ever woven together. I wished I had these videos when I was learning in school. Super helpful. Thank you. Teaching is both an art and a science 🎨📚, and only a few truly master it. You are one of those exceptional individuals. I’ve spent hours watching your videos, one after another, and they are simply brilliant 🌟. Your explanations are incredibly descriptive, using the simplest language woven together seamlessly. I only wish I had access to these videos when I was in school 🎓; they are immensely helpful. Thank you! 🙏

This playlist is a brilliant internet diamond: state-of-the-art quality video, very didactic flow, prime material content made simple, making abstract concepts turned from boring into fun and understandable. I truly appreciate your dedication, love and time put into this. The rare magic of teaching concepts to newbies or tech-savvy professionals was accomplished! And a fun reference to IT Crowd is just the cherry of the cake!! Good job! ❤️📺

Thank you for these videos. I was struggling in class because my teacher goes off topic a lot. But this solidified it for me.

Thanks for these. I have been on a networking hunt. I have some experience with MLOps, and it was a mess trying to understanding Networking concepts in K8, as well as REST APIs. This playlist is life-saver. I am curious to expand my Networking knowledge more. Thanks again.
