A list of frequently asked questions (FAQs) is often used in articles, websites, email lists, and online forums where common questions tend to recur, for example through new user messages or queries related to common knowledge gaps.
The purpose of an FAQ is usually to provide information about common questions or concerns; however, the format is a useful way to organize the information, so a text consisting of questions and their answers can be called an FAQ whether or not the questions are actually common.
