◆And we will end up programming software, which is Arduino IEEE. And we will explain how to download and install the software. This is the world that we are using, as you can see in this image. 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 would be agents.
◆And this protocol, the client here. Initiates communication by making a request for a specific or beige using H-2B 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 page pages delivered by a server are mostly ACM documents or PSP documents.
◆Now, let's take a quick example. This plaza is old client now free, right, Google Dotcom. It will provide HGTV, 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.
