A citation points towards a specific source of information, and contains all the information you need to find it.
You'll find citations in textbooks, encyclopedia articles, academic books and journal articles. Lists of citations are called "Works Cited" or "Bibliography" or other names, depending on the discipline.
Here's a citation to a journal article:

Distinguishing Features of a Journal Article

The citation specifies the exact volume and issue of the journal, plus the article's first and last page numbers.

Italics, bolding, and enclosing text in "quotation marks" are not distinguishing features, because their use varies among journals, disciplines and publication styles.
