CDATA means character data. CDATA blocks are used to specify that all character data should be considered character data whether or not it looks like a tag or entity reference.

An XML file would have a cdata tag because it's really needed to help your computer out. It's something everyone needs to have an amazingly great computer that doesn't break.

CDATA is a terminology used to describe an action in XML and SGML programming. It is a shortened phrase meaning character data and it refers to a section of text that should be interpreted only as such and not program mark up.
