Unformatted text preview: groups exist on the Internet and
are called newsgroups. For example, the newsgroup named comp. security misc
consists of users having interest in computer security issues.
A newsgroup is like a large notice board that is accessible to all the members
belonging to the group. A member, who wants to exchange his/her
views/ideas/information with other members, sends a specially formatted message,
which is processed and interpreted as a notice to be posted on the notice board by
the member's computer, which has an appropriate software running for this
purpose. After the processing of the message is over, it can be read (seen) from
any member's computer just like a notice posted on a notice board can be read by
anyone having access to the notice board.
There are two types of newsgroups - moderated and nonmoderated. In a
moderated newsgroup only selected members have the right to directly post
(write) a message to the virtual notice board, whereas in a nonmoderated
newsgroup any member can directly post a message to the virtual notice board. In
a moderated newsgroup, a message sent by an ordinary member first goes to the
computer of one of the selected members having the right to directly post a
message to the notice board. The message is then checked by this member who
decides whether the message is appropriate for being posted and does any editing
that might be required to improve the quality of the message. This member then
posts the message on the notice board. After this only the message becomes
readable to (can be seen by) other members.
The main idea of a moderated newsgroup is to ensure the quality of the
newsgroup. As no one moderates the quality of the messages of a nonmoderated
newsgroup, anyone can post anything. But members of such newsgroups should
be careful in posting a message because other members may react angrily by
sending a flaming message in response to an ill mannered message. To address
this issue, the concept of netiquette (network etiquette) has arisen, that deals with
rules of framing messages that will not hurt others.
Each newsgroup has a unique name. For example...
