Just a little bit about the technical side… Markup Languages
A markup language is a set of codes that determine how Web content looks or how it is structured.
HTML (hyptertext markup language)
XML (extensible markup language)
Just a little bit about the technical side… Markup Language Viewers
In order to display the content but not the codes, the coded content must be viewed using the right kind of software.
HTML viewer = Web browser
Examples: Internet Explorer, Mozilla Firefox, Safari
XML viewer = RSS aggregator
Aggregators are also called feed readers.
Examples: Bloglines, Google Reader
