Simply we can say that data related to data is Meta data. Specifically, data those carry information about one or more aspects of data can be called Meta data.
 
For example, time or date created, basic information about a sound file (music) like creator, author, when created, who is the lyricist etc.
 
For an image, the Meta data (or Meta content) can be of size of picture, depth of color, resolution etc.
