[00:00:00]Welcome back to our channel. So, students in this video we will discuss unit number five in web technology. So, in unit number five I have given only one question. So, that one question only I'm explaining in this video. So, that question only will come in the examination as I have already discussed before one month only in our channel.

[00:00:22]So, this video in this video I will give the answers, okay? So, what is that question means XML? That is extensible markup language, okay? If you're finding XML in your question, XML stylesheet or XML doc, XML DOM, anything, if you're finding XML in your question, you need to write it this answer only. What is that it means? XML stands for extensible markup language. Extensible markup language, it is same like HTML. XML was uh designed to carry out the data, not to display the data. Basically, whatever the programs we are we will use in the HTML or any JavaScript, it will have some coding language. But here in extensible markup language, that is in XML, it is a user-defined language, okay? In you can uh use the coding in English only. English is a universal language, no? So, it will not have any specific rules and regulations. It it won't have any programming languages.

[00:01:26]Got it? XML was designed to transport and store data with the focus on what data is XML document. What it will do?

[00:01:35]It will store data and it will focus the data and it will share data, whatever the documents you are having in XML. XML was created to structure, store, and transport information. XML was created to whatever the structured and the storage and whatever the transport information we are having, we will use it, okay? Next, uh structure of XML document. What is the structure of XML document we are having? It is a form of tree structure tree structure.

[00:02:06]Means it will have root element, child element, sub child. Okay? What is the format and what is the syntax of XML is whatever this you are having.

[00:02:19]Whatever this you are having, XML version is equal to {question mark} XML version is equal to 1.0. That is the syntax of the XML document. Here you will have root element, here you will have sub element, here you will have sub child element, okay? Root element, child element, sub child element, okay? Sub child element open close. For example, I'm saying root element is mobile phone. Okay?

[00:02:49]Child is Android and sub child is Oppo you will have. Okay? Vivo you will have like that, okay? That is called means if you click on one thing means like that another document will open. Okay? Like that it is a tree structure based programming language. You got it? So, I hope you have got understood. And the next you need to learn what are the features of XML you are having. So, that mostly I have written seven features.

[00:03:15]You need to remember the seven. What is it is easily convertible. Whatever as it is a universal language as it is as it is having a English language, it is easily convertible. Okay? Whatever you are writing the others perspective of the format, it will easily convertible.

[00:03:33]Got it? Next you are having secure data transfer. While transferring your data from one to another, your data will get security and it will be away from the hackers. Okay? It will give certain security protocols to you all, okay?

[00:03:50]Next you will have XML as a universal language. Why it is called a universal language? Because whatever the desktop applications you are using that can be stored whatever you are having universal language is English. Got it? Next allows XML validation. Allows XML validation is nothing but DTD and XML schema. It will allow you to go into the XML schema or the validation of that, okay? And new create new language. What is create new language? It creates wireless markup language. You don't need to have any wireless wired markup language. Without wireless you can do all the programming things. And sixth one is it provides Unicode. Unicode means it will whatever the communication is written in the human form, it will is understand that human form. Okay, it supports and it will performs whatever the task you're performing that will be allowed, okay?

[00:04:52]And the last one students, easy and efficient data sharing.

[00:04:57]Easy and efficient data sharing means whatever the data you are sharing through the software, it will share easily and accurate data will get provided and it will stay with the software and hardware configurations also. And uses of XML also you need to learn and you need to write that for the eight marks. And here it is used to exchange data and the content and document will be there. Database and storage capacity will be there. HTML will have a separate language. Whatever you have learned till now that you need to convert it by the answers as your own, okay? So this is about the video students. I hope that you have got clarity and this one question is enough from unit number five, okay? Hardly I have given only nine or eight questions in whole overall web web technologies and remaining chapters also have already uploaded. You just check out and watch the videos and all the very best for your examination as well as the preparation of your last exam in semester four. And I hope that question paper will get easy and you will rock in your examination.

[00:06:09]Because we are near to 50k subscribers.

[00:06:11]Let us finish 50k subscribers by June end. So see you all in the next video and after completing examination let me know in the comment section whether the questions are repeated or not, okay? See you all in the next video. Bye-bye students.
