Html & XHTML

As reference from on of the definations from google :-
HTML:-
"WWW documents are normally written in Hypertext Markup Language (HTML), the native language of the WWW. HTML enables links to be specified, and also the structure and formatting of Web documents to be defined. HTML documents are written in plain text, but with the addition of tags which describe or define the text they enclose. For example, a link is defined by the ANCHOR tag placed around the hyperlinked text. It specifies the URL of the 'linked to' document, eg Web Search Tools HTML is an evolving standardwww.terena.nl/library/gnrt/appendix/glossary.html"

XHTML:-
"The Extensible HyperText Markup Language (XHTML™) is a family of current and future document types and modules that reproduce, subset, and extend HTML, reformulated in XML. XHTML Family document types are all XML-based, and ultimately are designed to work in conjunction with XML-based user agents. XHTML is the successor of HTML, and a series of specifications has been developed for XHTML. ~from w3.org HyperText Markup Language (HTML) Home Pagebizgrok.com/help/definitions/"
