Like for example, what does a son do to remember our complex IP address like google.com, instagram.com, facebook.com? The.w is a subdomain prefixed to this domain, indicating that the site is located on the World Wide Web.
That is why we say son www google.com clearly and not, now let me talk in simple language about what a domain name is.

Like son, two extensions are same like our Google, did you understand all this or not? Any doubt?
Okay brother, I will talk to you after this. of www. There are many important things to ask you. I am going to talk.
So son, note down the full form of www.
World Wide Web question comes to you, sometimes it is given in multiple choice question, sometimes in MCQ, sometimes it asks you in very short what is www or full form of www or www stands for, all of these have the same meaning, same answer, note down word wide web, please note down word wide web, note down word wide web, son, note it down quickly, come on brother, let us move ahead.

Ok?
Okay brother, if I understand the full form of HTML, then the full form of HTML is Hyper Text Markup Language, what will happen son, the full form of Hyper Text Markup Language ( XML) is Extensible Markup Language. Take note of it.
Note down the full form of XML, son. Extensible Markup Language.
Extensible Markup Language. Take note of it. It is an extensible markup language. Keep in mind that the full form of HTML is Hyper Text Markup Language and the full form of XML is Extensible Markup Language my dear.
Its purpose, if I talk on behalf of the populace, is to present HTML data in a beautiful way.
Ok? To present data in a beautiful way, we use it to present data in HTML in a sonar and beautiful way.
But in XXl, that means it is used to define the structure.
Whose son? We use this to define our structure.
We use this to define our structure.
Right son, I talk about tags here if son, I talk about tags here. If there is a tag then in HTML there is heading one paragraph anchor tag, in XML what do you do as per your own choice, son you can create tags in it.
Like son name, you can make son name as per your choice.
What can Price do with this approach, son? You can make things. Please note that I am talking about case sensitivity.
Ok? If I talk to you about case sensitivity, then this is our case sensitivity.
Case insensitive sorry this is our case insensitive my dear and this is our case sensitive.
Please understand that this is case sensitive. It doesn't happen or it happens in XML and that HTML would be case insensitive.
Ok?
Whatever is written has to be written as it is, brother.
And this is case sensitive and what is there in it?
Write it in any way you like. You can write it as per your wish, whether it is lower, upper, capitalized or proper.
Ok?
On the basis of nature, this will come in our HTML which is a presentation language, son, and XML which is a data description, son, what will it come in, son, it will come in presentation and this will come in our data description, my dear, in which language does it come, son?
