What is our observer and how it works?
Well, Observer is a place which stores, processes and delivers web pages to clients.
What clients is nothing but our browser on our laptops and smartphones.
As you can see in this image.
The communication between client and server takes place using a special protocol called Hypertext Transfer
Protocol, which basically at STB, I think that you are familiar with this one because you see it in
almost all lengths and all the patients in this protocol, the client here.
Initiates communication by making a request for a specific or beige using to protocol, and the server
then responds with the content of that what page or an error message if it was unable to do that?
Like the famous 404, it'll page pages delivered by a server are mostly ACM documents or PSP documents.
Now, let's take a quick example.
This plaza is our client.
No free ride.
Google Chrome, it will provide HDTV, which we already mentioned.
And it will ask the server to deliver this Web page, which is Google dot com.
Now this request will go from the Wolf client, which is this browser to Google's servers.
And Google servers will respond with this page content, which is basically an image and two buttons.
So this is us communicating with Google Server using our client, which is this browser.
I think now that this idea is more clear and we are going to transfer our sport to our server and we
are going to write a small code so that whenever someone since I request to our ISP board server, it
will respond with the pages that we did create inside it.
Thanks for watching this lesson.
