Internet Network :
Once you've become adept at using e-mail, you may want to communicate with others on the Internet who share your interests. Newsgroups are one way to do this; the other is through an electronic discussion group. An electronic discussion is a group of persons who have come together to discuss a particular topic via e-mail. There are several methods that network users can use to participate in electronic discussions; however, the basic purpose is to bring together persons with similar interests to share information, ideas, problems, solutions, and opinions. Since an electronic discussion is conducted by e-mail, it's commonly called a mailing list.
If you find yourself interested in a topic, you can subscribe to a suitable mailing list. From then on, any message sent to the mailing list is automatically distributed as electronic mail to you--as well as to all previously subscribed members of that particular discussion. The beauty of a mailing list is that traffic (the mail generated by that list) covers a specific topic and the
mail it generates comes straight to your electronic mailbox, without any extra work on your part. There are thousands of mailing lists operating on the Internet, dedicated to myriad topics. Some are created to serve local needs only (i.e., a list for the members of a regional computer user group), while many are open to anyone on the network. There are discussions on professional topics, vocational subjects, and topics of personal interest. You can roughly separate the thousands of mailing lists available on the Internet into the following groups:
Types of discussion lists:
Moderated vs. Unmoderated Lists
Mailing lists can be moderated or unmoderated. The distinction is whether messages are automatically forwarded to all subscribers (unmoderated) or whether a moderator (a human being) first screens and perhaps combines similar messages before sending them to subscribers (moderated).
Open vs. Closed Lists
Electronic discussions can also be "open" or "closed." Anyone can subscribe to an open discussion, but a closed discussion is limited to a particular group of persons, for example, those in a particular professional field.

Introduction to network news:
Network News (sometimes referred to as Usenet News) is a service comprised of several thousand electronic discussions providing users an effective way to share information with others on just about any topic.
If you're unclear about the concept of Network News, it's helpful to think about a bulletin
board that you might see on campus.
Here, one might find posted messages advertising a futon for sale, asking for students to join a math study group. In the newsgroup environment, the same kind of process take place:
User X may access a newsgroup on a particular topic and post a message, question, or respond to a previously posted message, and anyone accessing that newsgroup would then be able to see User X's message.
Network News newsgroups provide this same kind of forum online, where users have access to the messages posted by all other users of that newsgroup.
Network News has been described as an "international meeting place" where you're likely to find a discussion going on just about anything.

How Does Network News work?
Messages posted on Network News newsgroups are sent from host computer to host computer all over the world, using the network news transfer protocol.
Because Network News newsgroups are located on one server, Network News is a very efficient way to share information that might otherwise be disseminated to several individual users.
This way, several people can read a given newsgroup message, but the host system stores only one copy of it.
