Xml (Extensible Markup Language) is a prgramming language that defines a set of rules that are both human-readable and machine-readable.

The correct answers are HTML and XML are MARK UP languages used to format data. In the case of HTML it is used to format text and graphics for display through a browser. As such it is primarily used to display "Pages" on the WEB.

In the case of XML it is used to identify data as a standard way to share data to a variety of applications.

A Markup language is characterized by "tags" that identify the data within the tags. For example if you surround a text string in HTML with the tags

<b>text string</b>

It will display text string as bolded. Similarly in XML you might identify a data field with tags indicating the filed name. For example:

<address>123 Elm Street</address>
