What newsgroups are and how they work
*Newsgroups* are a means of public discussion and distribution of
material to a large number of people. They share this fundamental
purpose with electronic mailing lists, Web-based bulletin boards,
etc. Newsgroups can appear to be very much like one of these
other kinds of forums, depending on how you access them.
Nevertheless, newsgroups are different from them in important
ways, and each kind of forum has its own quirks, advantages and
disadvantages.
Newsgroup messages are not stored in a single central location (as
with a Web-based bulletin board) or distributed from a single
central location (as with an electronic mailing list). Instead,
they are stored on a multitude of *news servers* that are operated
by Internet service providers (ISPs) for their customers, by
schools and universities for their students and staff, by
companies for their employees, by commercial and free News Service
Providers (NSPs), etc.
When someone posts a message in a newsgroup, it is first stored on
their provider's news server. That server then distributes
copies of the message to its *peers*, that is, to other servers
with which it has agreed to exchange newsgroup messages directly.
Those servers then distribute copies to *their* peers, and so on,
until (in principle) all the servers which carry that newsgroup
have a copy of the message. When someone reads a message in a
newsgroup, they are reading the copy that is stored on their
provider's news server.
Some newsgroups are *moderated*. In these newsgroups, the
poster's server sends messages directly to a *moderator* for
inspection. If the moderator approves a message, they post it
on their provider's news server, and it propagates from there to
other servers (including yours).
For more details about the newsgroup distribution mechanism, see:

People read and post to newsgroups using *news clients* (also
called *newsreaders*) such as Mozilla Thunderbird or Microplanet
Gravity, and a variety of other software packages for Windows,
Unix, Linux, macOS and other operating systems. These newsreaders
communicate with news servers via the NNTP protocol (Network News
Transfer Protocol). NNTP also specifies how news servers exchange
messages with each other.
Some servers make newsgroup messages available via a Web-based
interface that can be used with any Web browser, for example
