   Frequently Asked Questions.]
   A list of questions and answers concerning a specific topic,
   such as how to use a particular computer program. Many such
   lists contain answers to the most commonly asked questions
   about that topic, however the questions need not derive from
   actual queries. Such lists are often maintained in electronic
   form and made available on the World Wide Web. [acronym]

    1. A Frequently Asked Question.

    2. A compendium of accumulated lore, posted periodically to high-volume
    newsgroups in an attempt to forestall such questions. Some people prefer
    the term ?FAQ list? or ?FAQL? /fa'kl/, reserving ?FAQ? for sense 1.

    This lexicon itself serves as a good example of a collection of one kind of
    lore, although it is far too big for a regular FAQ posting. Examples: ?What
    is the proper type of NULL?? and ?What's that funny name for the #
    character?? are both Frequently Asked Questions. Several FAQs refer readers
    to the Jargon File.

FAQ list

    (FAQ, or rarely FAQL, FAQ list) A document
   provided for many Usenet newsgroups (and, more recently,
   web services) which attempts to answer questions
   which new readers often ask.  These are maintained by
   volunteers and posted regularly to the newsgroup.  You should
   always consult the FAQ list for a group before posting to it
   in case your question or point is common knowledge.

   The collection of all FAQ lists is one of the most precious
   and remarkable resources on the Internet.  It contains a
   huge wealth of up-to-date expert knowledge on many subjects of
   common interest.  Accuracy of the information is greatly
   assisted by its frequent exposure to criticism by an
   interested, and occasionally well-informed, audience (the
   readers of the relevant newsgroup).

   The main FTP archive for FAQs is on a computer called RTFM
   at MIT, where they can be accessed either by group
   (ftp://rtfm.mit.edu/pub/usenet-by-group/comp.answers/) or by
   hierarchy (ftp://rtfm.mit.edu/pub/usenet-by-hierarchy/).
   There is another archive at Imperial College
   (ftp://src.doc.ic.ac.uk/usenet/news-info/), London, UK and a
   web archive in Ohio
   (http://cis.ohio-state.edu/hypertext/faq/usenet/top.html),
   USA.

   The FAQs are also posted to Usenet newsgroups:
   news:comp.answers, news:news.answers and
   news:alt.answers.
