Can someone explain/clarify one of the images for me.
U1L13 Resource - HTTP and Abstraction on the Internet
Page 2
There is a graphic with HTTP and DNS side by side connecting to TCP.
Why is that? Why not one over the other?

HTTP and DNS work side by side. The HTTP is the protocol a client computer would use to communicate over the internet through the DNS. The DNS also uses this protocol to communicate with other computers. They are not dependent on each other. They work together to make the top layer of the internet. I hope this makes sense!
Help!!!
This is my first year teaching this class and I am a Spanish teacher. I do not understand what to do in this lesson. Could someone explain to me step by step what to do? I am panicking right now!!!
The following are the instructions. I really do not know what or how to do this.
"You will use your browser’s developer tools to discover what kind of HTTP traffic is associated with visiting different types of websites. You and your partner are going to look at least 5 different types of websites:
For each type of website below, follow these steps:
Thank you so, so much
Hello @rossiai
The key part of this activity involves observing traffic using a browser’s developer tools. For Google Chrome, those can be found in the more options icon, in the top right hand of the browser. Click “More Tools” then “Developer Tools”. The Developer Tools should pop up. To view the Network traffic, the tab can be selected at the top of the Developer Tools. If it does not show up, click the >> icon and then select Network. To view the traffic on a page, reload the page and watch what happens!
Cheers!

Hi, there. Would you also help me with this?
The following line is from a Wikipedia article. I really do not understand what it means.
“the quad-dotted IP address 192.0.2.235 represents the 32-bit [decimal] number 3221226219" https://en.wikipedia.org/wiki/IPv4
My problem is that I thought that 192.0.2.235 was already in base 10.

Hi @rossiai
Long answer: I had to look this up myself, and I found this website to have a helpful explanation, although it does require a lot of reading.
Short answer: There is math involved giving weight to each part of the quad-dotted IP address when converting to one single decimal number.
Cheers!

Thank you Hannah. I will try to go over it this weekend. I could not find anything myself. I am not sure I will understand, but I will give it a try.

Good answer because my student just used it for hers in this lessons. I know everything is searchable but gotta love that the teacher’s forum is wide open too.
