How newsgroups work Edit
Newsgroups are large messaging systems that consist of text messages and encoded files (e.g., pictures, sounds, movies, programs) organized into categories of interest with multiple subcategories and topics. The Usenet, which is the Internet network where newsgroups are structured, hosts hundreds of thousands of newsgroups at any given time.
The news service provider, usually the user's ISP, determines the newsgroups available on any particular news server. Free news servers also are available but usually provide access to a limited number of newsgroups. Subscription news servers are available that provide access to an unlimited number of newsgroups.
Newsgroups currently operate using the Internet and a protocol, or a set of operating specifications, known as Network News Transfer Protocol (NNTP). This protocol is similar to the e-mail protocol (SMTP). Newsgroup servers are computers that usually are interconnected and store newsgroup messages for distribution to users. Users can participate passively by reading the contents of the group postings, or participate actively by posting or requesting information from other users.
Some newsgroups are moderated and therefore cannot be posted to by individuals — articles posted to them must be mailed to a moderator who will post them for the submitter. In an unmoderated newsgroup, the message is posted directly without editing. The majority of newsgroups are unmoderated.
