Usenet News is a world wide discussion system consisting of thousands of newsgroups organized into hierarchies by subject. Users read and post articles to these newsgroups using client software. The "news" is held for distribution and access on the news server. Because newsgroups tend to generate large amounts of Internet traffic, you may wish to consider the method in which you intend to receive Usenet news.
There are two ways to accept Usenet News: as a "push" or "pull" feed. With a "push" feed, news articles are "pushed" onto your news server, whether or not your users read those articles. With a "pull" feed, your news server has all of the headers for the collection of Usenet News articles, but does not retrieve the article itself unless it is specifically requested by a user.
