00:00:01,290 --> 00:00:03,690
What is our observer and how it works?

2
00:00:04,920 --> 00:00:13,590
Well, Observer is a place which stores, processes and delivers web pages to clients.

3
00:00:14,770 --> 00:00:21,370
What clients is nothing but our browser on our laptops and smartphones.

4
00:00:23,390 --> 00:00:24,770
As you can see in this image.

5
00:00:27,690 --> 00:00:37,830
The communication between client and server takes place using a special protocol called Hypertext Transfer

6
00:00:37,830 --> 00:00:44,970
Protocol, which basically at STB, I think that you are familiar with this one because you see it in

7
00:00:45,090 --> 00:00:51,900
almost all lengths and all the patients in this protocol, the client here.

8
00:00:53,590 --> 00:01:03,370
Initiates communication by making a request for a specific or beige using to protocol, and the server

9
00:01:03,370 --> 00:01:11,560
then responds with the content of that what page or an error message if it was unable to do that?

10
00:01:12,190 --> 00:01:22,510
Like the famous 404, it'll page pages delivered by a server are mostly ACM documents or PSP documents.

11
00:01:23,630 --> 00:01:25,970
Now, let's take a quick example.

12
00:01:28,880 --> 00:01:32,570
This plaza is our client.

13
00:01:33,960 --> 00:01:35,350
No free ride.

14
00:01:35,450 --> 00:01:43,400
Google Chrome, it will provide HDTV, which we already mentioned.

15
00:01:44,590 --> 00:01:50,180
And it will ask the server to deliver this Web page, which is Google dot com.

16
00:01:50,950 --> 00:01:58,360
Now this request will go from the Wolf client, which is this browser to Google's servers.

17
00:01:58,900 --> 00:02:04,900
And Google servers will respond with this page content, which is basically an image and two buttons.

18
00:02:05,650 --> 00:02:13,630
So this is us communicating with Google Server using our client, which is this browser.

19
00:02:14,440 --> 00:02:23,290
I think now that this idea is more clear and we are going to transfer our sport to our server and we

20
00:02:23,290 --> 00:02:32,530
are going to write a small code so that whenever someone since I request to our ISP board server, it

21
00:02:32,530 --> 00:02:37,210
will respond with the pages that we did create inside it.

22
00:02:38,640 --> 00:02:39,840
Thanks for watching this lesson.

23
00:02:40,500 --> 00:02:42,810
This is us from educational engineering team.
