Markup languages

Are languages used to create web documents. They use instructions, known as markup tags, to format and link text files.

• HTML

  or HyperText Markup Language defines the way how images, multimedia, and text are displayed in web browsers. It includes elements to connect the documents (hypertext) and make the web documents interactive. It uses tags to define the structure of your text. Elements and tags are defined by the < and > characters (angle brackets).

• XML

  eXtensible Markup Language is not limited by a fixed set of pre-defined tags as HTML, it enables the programmer to define his own tags.

• XHTML

  a short for eXtensible HyperText Markup Language, a hybrid between HTML and XML.

• Voice XML

  makes Internet content accessible via speech recognition and phone. Instead of using a web browser on a PC, you can use a telephone to access voice-equipped websites. You just dial the phone number of the website, give spoken instructions and get the required information.
