Markup language vs. programming language
A markup language is not a programming language it is a series of keywords, names, and tags that are used to help present information. A programming language can not only present information but also accept and load new data, manipulate the data, and control how the information is presented based off of conditions.
A good example of how markup language is used is the HTML that is used to display the text on this web page. However, to do something more sophisticated such as a search for keywords on this page and other pages a programming language would have to be used.
