 So, I feel the next important idea that needs to be communicated is about the rules of communication. What are the rules that the packets need to follow, are the different type of rules from one source to destination that they need to follow under different circumstances. I agree, I think it is right time to introduce the concepts of transport layer. Do you have any animations for that too? Yes, you are right that the next idea that we need to convey is how the entire web page is sent from one end of the network to the other. And of course, we have an animation for that. So, what we can do now is look at how Aamir helps his friend Navneet in order to fulfill a travels and tours order through this animation. As usual, we will then have a question and then discuss about the question subsequently.
