Very good work.
I have a small concern - in OSI model section - you have started with Application layer - which is layer number 7 - and in our document its getting number 1 - according to how you started.
Do you think it makes sense to start with the physical layer - so we start from the bottom of the model and then go up and data goes up. Point number will also get automatically corrected then.

What are the sources that you used to learn about this.
Which model did you like personally and why?
which one of these do you think is more in use?

@udeysingh95, I have we start from the bottom when we are at the receiver side and we start from the top when we are on the sender side. In this, I have discussed the sender side workflow of the model. So we start from the application layer and go down to the physical layer.

Which model did you like personally and why?

I liked both of the models as they are almost similar in structure, but I would say I enjoyed learning the OSI model. It was very interesting and I was fully focused while learning it. When I started learning the TCP/IP model mostly the language was the same.
But I know that they are very different from each other. At last, I would like to say
The tagline "OSI is a reference model whereas TCP/IP is an implementation model". 😄

which one of these do you think is more in use?

I will go with the OSI model, as it acts as a base of networking, through this model I understood how the data actually travelled from sender to receiver.

The video was very interesting mainly the way he explained the video. Thanks for the link.
