1 00:00:02,170 --> 00:00:11,770 Welcome, my friends, in this section, we will study about HDTV before language DDP is hypertext transfer 2 00:00:11,770 --> 00:00:12,310 protocol. 3 00:00:12,320 --> 00:00:18,790 It's a protocol that we very commonly used to access the World Wide Web and other protocols such as 4 00:00:18,790 --> 00:00:21,700 FPP exist, which is the financial protocol. 5 00:00:21,760 --> 00:00:26,650 We will be focusing on the HDTV protocol in this section. 6 00:00:27,010 --> 00:00:34,690 We will be learning about the various aspects of HTP, particularly the two constituents of the request 7 00:00:34,840 --> 00:00:35,880 and the response. 8 00:00:36,370 --> 00:00:42,700 Also, we will study about two types of requests, particularly the request and it was request. 9 00:00:44,490 --> 00:00:45,680 So let's move forward. 10 00:00:49,830 --> 00:00:57,600 Let's start the lecture a bit of episode, what episode is of episode we're constantly is functioning 11 00:00:57,750 --> 00:01:01,020 on a computer and it's trying to get a request. 12 00:01:01,590 --> 00:01:04,590 It will it will accept a request from a client. 13 00:01:04,950 --> 00:01:10,030 So it processes the request and then sends the response back to the client. 14 00:01:11,010 --> 00:01:12,600 This response can be an e-mail. 15 00:01:12,990 --> 00:01:16,710 It can be a text, it can be PDAF, it can be even an MP three file. 16 00:01:17,250 --> 00:01:20,940 But we will be mostly concerned with HTML files. 17 00:01:22,740 --> 00:01:25,920 The example of VIPs can be an Apache Web server. 18 00:01:26,220 --> 00:01:31,370 It's a very common service IRS, Microsoft is so it is again very common. 19 00:01:31,620 --> 00:01:37,050 So where to to process and send static files? 20 00:01:37,620 --> 00:01:41,810 That is for dynamic files we use about Yitong and that's what we will be using. 21 00:01:41,820 --> 00:01:45,260 So it is a dynamic way of handling Java. 22 00:01:45,450 --> 00:01:48,860 So we will be using a bunch of banquette as an example. 23 00:01:50,710 --> 00:01:54,790 So what is it that client of your client is essentially your browser? 24 00:01:54,910 --> 00:02:01,990 It can also be an Android phone application or it can be an iOS application on your Apple phone. 25 00:02:02,440 --> 00:02:08,710 But primarily we're concerned with that based applications on browsers. 26 00:02:08,890 --> 00:02:10,900 Example is a Firefox. 27 00:02:11,740 --> 00:02:13,380 What does a client actually do? 28 00:02:13,390 --> 00:02:15,540 It makes the request to the Web server. 29 00:02:15,670 --> 00:02:23,000 So the Web server was waiting for a request from the client and the client actually makes the request 30 00:02:23,000 --> 00:02:30,460 to the Web server and it gets a response from the server web server in the form of e-mail or whatever 31 00:02:30,460 --> 00:02:30,730 it is. 32 00:02:30,730 --> 00:02:38,530 And it renders that response that the client, the browser understands what this is supposed to mean 33 00:02:38,710 --> 00:02:40,810 and shows you visually. 34 00:02:40,810 --> 00:02:44,890 It shows you different elements of the HDMI tag and it shows it. 35 00:02:45,330 --> 00:02:46,930 So that's sort of explained this. 36 00:02:48,340 --> 00:02:57,490 What is it essentially is a protocol their client and servers use on the web to communicate. 37 00:02:57,730 --> 00:03:06,550 So of client and a Web server, both are using HGP protocol to request in response to communicate with 38 00:03:06,550 --> 00:03:07,080 each other. 39 00:03:08,550 --> 00:03:13,970 The server uses to send a statement to the client mostly, why are you sending e-mail? 40 00:03:13,970 --> 00:03:20,370 It can be a text file also, but they send an e-mail file and that is the browser, how to display the 41 00:03:20,370 --> 00:03:21,500 content, but they use it. 42 00:03:21,900 --> 00:03:25,020 The estimate is is a structured language. 43 00:03:25,200 --> 00:03:31,710 It's a that based language, hypertext markup language, the full form of estimate. 44 00:03:31,720 --> 00:03:36,570 And you might have some idea how it basically works. 45 00:03:36,570 --> 00:03:38,790 And a browser renders this estimate. 46 00:03:39,270 --> 00:03:43,700 So that is the essence of this next lecture. 47 00:03:43,710 --> 00:03:46,080 We will go to response.
