Q.what is HTML and what is it for?
First of all,the acronym HTML means Hypertext markup language. HTML is a method of describing the format of documents which allows them to be viewed on computer screens.HTML documents are displayed by web browsers,programs which can navigate across networks and displayed by web browsers,programs which can navigate across networks and display a wide variety of types of information.
HTML pages can be developed to be simple text or to be complex multimedia extravaganzas containing sound,moving images,virtual reality,and java applets.Most internet web pages lie somewhere along that continuum,being mostly text but with a few images to add interest and variety.
The internet is global phenomenon which can provide documents from servers across the world to browser clients which can be in any location.if documents are to be readily exchanged across such a vast and complex network,some sort of global protocol is required which allows that information to be viewed anywhere.
The global publishing format of internet is HTML.It allows authors to use not only text but also to format that text with headings,list,and tables,and to include still images,video,and sound within the text.readers can access pages of information from anywhere in the world at the click of a mouse-button.Information can be downloaded to reader's own PC or workstation,printed out or e-mailed on to others.HTML pages can also be used for entering data and as the front-end for commercial transactions.
It's probably also worth briefly mentioning what HTML isn't.It's not a programming language you can't write an HTMl program and expect anything to happen.It's not a data description language-the HTML that you write won't tell anyone anything about the structure of your data,although XML will add those capabilities should you choose to use them.Finally HTML isn't really very complicated although the creators of WYSIWYG authoring tools would like you to think that it is.
