It is Hypertext Markup Language (HTML)
Html is a standard markup language used to create web pages. In full form, it stands for Hyper Text Markup Language.
Hypertext Reference.
An identifier in the HTML document, that tells to the browser which type of HTML it needs to use to show contents of that document. Specifying different versions of HTML will result in different behavior of the document. If the type hasn't been specified at the beginning of HTML document the browser might load it slowly or even with the errors. Usage: <!DOCTYPE HTML /*Here goes type of the document specification (DTD)*/>
The declaration must be the very first thing in your HTML document, before the tag.The declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.In HTML 4.01, the declaration refers to a DTD, because HTML 4.01 was based on SGML. The DTD specifies the rules for the markup language, so that the browsers render the content correctly.HTML5 is not based on SGML, and therefore does not require a reference to a DTD.Tip: Always add the declaration to your HTML documents, so that the browser knows what type of document to expect.

The full form of XHTML is Extensive Hyper Text Markup Language. It is a form of HTML only and is similar.
A Document Type Definition (DTD) is a set of markup declarations that define a document type for an SGML-family markup language (SGML, XML, HTML).A DTD uses a terse formal syntax that declares precisely which elements and references may appear where in the document of the particular type, and what the elements' contents and attributes are. A DTD can also declare entities which may be used in the instance document.
The whole Doctype tag in html 4 is shortened in html 5. Say in html 4 you saw some code like this at the top: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Now you just use <!DOCTYPE html>
No, because they are essentially the same thing. HTML came before XHTML, and can be ill-formed but still acceptable. XHTML is just well formed HTML with the inclusion of a DTD at the very top.
what is different between internal dtd and external dtd and advantages and disadvantage plz tell me answer
ROM is an acronym for read-only memory and HTML stands for hypertext mark-up language.
