FAQ (Frequently Asked Questions) are a series of questions and answers all pertaining to a certain topic. "FAQ" is sometimes pronounced as an acronym, fack, and sometimes as the initialism F.A.Q. (Since it originated in the text medium of USENET, there is no agreed-upon pronunciation.)

The FAQ is an Internet textual tradition originating from periodic summary messages posted to USENET newsgroups in an attempt to reduce the continual reposting of the same basic questions. On USENET, posting questions which are covered in a group's FAQ is often considered inappropriate, as it shows that the poster has not done the expected background reading before asking others to provide answers. Some groups may have multiple FAQs on related topics, or even two or more competing FAQs explaining a topic from different points of view.
