... y have. Any that one
is missing the other then transmits, and vice-versa. Because they are
computers, they don't mind running through thousands, even millions, of
these comparisons every day.
Yes, millions. For Usenet is huge. Every day, Usenet users
pump upwards of 40 million crawley ecommerce consultant characters a day into the system -- roughly
the equivalent of volumes A-G of the Encyclopedia Britannica. Obviously,
nobody could possibly keep up with this tennessee ecommerce consultant immense flow of messages. Let's
look at how to find conferences and discussions of interest to you.
The basic building block of Usenet is the newsgroup, crawley ecommerce consultant which is a
collection of messages with a related theme (on other networks, these
would be called conferences, forums, bboards or special-interest
groups). There are now more than 5,000 of these newsgroups, in several
diferent languages, covering everything from art to zoology, from
science fiction to South Africa.
Some public-access systems, typically the ones that work through
menus, try to make it easier by dividing Usenet into several broad
categories. Choose one of those and you're given a list of newsgroups in
that category. Then select the newsgroup you're interested in and start
reading.
Other systems let you compile crawley ecommerce consultant your own "reading list" so that you
only see messages in conferences you want. In both cases, conferences
are arranged in a particular hierarchy devised in the early 1980s.
Newsgroup names start with one of a series of broad topic names. For
example, newsgroups beginning with "comp." are about particular computer-
related topics.
These broad topics are followed by a series of more
focused topics (so that "comp.unix" groups are limited to discussion coalville ecommerce consultant
about Unix).
The main hierarchies are:
bionet Research biology
bit.listserv Conferences originating as Bitnet mailing lists
biz Business
comp Computers and related subjects
misc Discussions that don't fit anywhere else
news News about Usenet itself
rec Hobbies, games and recreation
sci Science other than research biology
soc "Social" groups, often ethnically related
talk coalville ecommerce consultant Politics and related topics
alt Controversial or unusual topics; not
carried by all sites
In addition, many host systems carry newsgroups for a particular
city, state or region. For example, ne.housing is a newsgroup where
New Englanders look for apartments. A growing number also carry K12
newsgroups, which are aimed at elementary and secondary teachers and
students. crawley ecommerce consultant And a number of sites carry clari newsgroups, which is
actually a commercial service consisting of wire-service stories and
a unique online computer news service (more on this in chapter 10).
3.2 NAVIGATING USENET WITH nn
How do you dive right in? As mentioned, on some systems, it's all
done through menus -- you just keep choosing from a list of choices until
you get to the newsgroup you want and then hit the "read" command. On
Unix systems, however, you will have to use a crawley ecommerce consultant "newsreader" program. Two
of the more common ones are known as rn (for "read news") and nn (for "no
news" -- because it's supposed to be simpler to use).
For beginners, nn may be the better choice because it works with
menus -- you get a list of articles crawley ecommerce consultant in a given newsgroup and then you
choose which ones you want to see.
To try it out, connect to your host
system and, at the command line, type
nn news.announce.newusers
and hit enter.
After a few seconds, you should see something like
this:
Newsgroup: news.announce.newusers Articles: 22 of 22/1 NEW
