1
00:00:01,100 --> 00:00:06,770
Running a Web application, so we've seen servers, clients, and we've talked a little bit about the

2
00:00:06,770 --> 00:00:13,670
technologies behind them, so where you may ask, where is the application?

3
00:00:14,270 --> 00:00:16,250
Where is the code?

4
00:00:17,000 --> 00:00:17,330
All right.

5
00:00:17,330 --> 00:00:22,070
So here I'm going to explain a little bit about how a Web application runs on a server.

6
00:00:22,730 --> 00:00:26,360
And, yeah, web applications run on servers.

7
00:00:27,230 --> 00:00:31,940
So now let's say that we have a completed project.

8
00:00:32,720 --> 00:00:35,210
So the code is already ready to function.

9
00:00:35,990 --> 00:00:43,490
Now to benefit from whatever the applications aims are, this code should be run by a server software.

10
00:00:45,320 --> 00:00:49,910
So on server computers, there is indeed special software called HTTP server.

11
00:00:50,500 --> 00:00:56,330
And of course, it's got all kinds of flavors such as Apache, IRS and nginx.

12
00:00:57,380 --> 00:01:04,610
All code files are then put under a special folder that belongs to the HTTP server.

13
00:01:05,360 --> 00:01:11,570
Then their software runs and processes the code and produces the associated output when a client requests

14
00:01:11,570 --> 00:01:11,720
it.

15
00:01:13,910 --> 00:01:20,750
Now, to speak in developer terms, we can explain that there are two sides for an application the front

16
00:01:20,750 --> 00:01:22,010
end and the back end.

17
00:01:23,150 --> 00:01:31,010
The front end is composed of the code that runs into the Web browser and a browser can only run HDMI

18
00:01:31,040 --> 00:01:33,860
access and JavaScript code, by the way.

19
00:01:35,340 --> 00:01:42,240
Now a server can run programming languages, databases and web frameworks on an operating system.

20
00:01:43,300 --> 00:01:51,850
So when you request a Web page from the server, the server will approve the request, then process

21
00:01:51,850 --> 00:01:59,320
the code and then produce the associated HTML file and then the server will send this file back to the

22
00:01:59,320 --> 00:02:01,840
client, which is the Web browser.

23
00:02:02,750 --> 00:02:08,630
So after the Web browser downloads all the files, it's going to combine and render them.

24
00:02:09,750 --> 00:02:13,000
And then display the page visually, as we can see.

25
00:02:13,950 --> 00:02:16,950
Now let's dive into some of the basics to understand them better.
