Frequently asked questions (FAQ) or Questions and Answers (Q&A), are listed questions and answers,
all supposed to be commonly asked in some context, and pertaining to a particular topic. The format is commonly used on email mailing lists and other online forums, where certain common questions tend to recur.
Meanwhile, on Usenet, Mark Horton had started a series of "Periodic Posts" (PP) which attempted to answer trivial questions with appropriate answers. Periodic summary messages posted to Usenet newsgroups attempted to reduce the continual reposting of the same basic questions and associated wrong answers. On Usenet, postind associated wrong answers. On Usenet, posting questions which are covered in a group's FAQ came to be considered poor netiquette, as it showed that the poster has not done the expected background reading before asking others to provide answers. Some groups may have multiple FAQ on related topics, or even two or more competing FAQs explaining a topic from different points of view.
