Network Groups

Network groups are a means for groups of people with common interest to connect with each other via internet. There are two major types of network groups namely; Mailing lists and Newsgroups.

Mailing lists: a mailing list is a group of e-mail names and addresses given a single name. when a message is sent to a mailing list, every person on the list receives a copy of the message in his or her mailbox. To add your e-mail name and address to a mailing list,you subscribe to it. To remove your name and address, you unsubscribe from the mailing list.

Types of Mailing lists

1.      Announcement list

One type of electronic mailing list is an announcement list, which is used primarily as a one-way conduit of information and may only be “posted to” by selected people. This may also be referred to by the term newsletter. Newsletter and promotional emailing lists are employed in various sectors as parts of direct marketing campaigns.

2.      Discussion list

Another type of electronic mailing list is a discussion list, in which any subscriber may post. On a discussion list, a subscriber uses the mailing list to send messages to all the other subscribers, who may answer in similar fashion. Thus, actual discussion and information exchanges can happen. Mailing lists of this type are usually topic-oriented (for example, politics, scientific discussion, health problems, joke contests), and the topic may range from extremely narrow to “whatever you think could interest us”. In this they are similar to Usenet newsgroups, another form of discussion group that may have an aversion to off-topic messages.
