Usenet newsgroup. A Usenet newsgroup is a repository usually within the Usenet system, for messages posted from users in different locations using the Internet.

Usenet (/ ˈjuːznɛt /), USENET, [1] or, "in full", User's Network, [1] is a worldwide distributed discussion system available on computers.

A newsreader, also known as a news client, is a software application that reads articles on Usenet, either directly from the news server's disks or via the NNTP. The well-known TCP port 119 is reserved ...
