In typography, a bullet is a typographical symbol or glyph used to introduce items in a list, like below:

  • (bullet)

It is most conveniently used in technical writing or reference works to introduce a series of related items. They may be short phrases or of paragraph length. The main point is that all need to be tied together under a general heading. Bulleted items, commonly called "bullets", are usually terminated with a full stop.
In computer programming, the bullet corresponds to Unicode character 0x2022.
