Usenet is a collection of user-submitted notes or messages
on various subjects that are posted to servers on a
worldwide network. Each subject collection of posted notes
is known as a newsgroup.
There are thousands of newsgroups and it is possible for you
to form a new one. Most newsgroups are hosted on
Internet-connected servers, but they can also be hosted from
servers that are not part of the Internet. Usenet's original
protocol was UNIX-to-UNIX Copy (UUCP),
but today the Network News Transfer Protocol (NNTP)
is used.
This is mostly access via newsgroup
readers, such as Outlook Express, that run as separate
programs.
