Newsgroup

A collection of articles on a given topic. When you write an article, you specify to which group or groups it should be sent.

Each newsgroup has a hierarchical name which suggests the topic of that group. Names consist of several words separated by periods. The first word in the newsgroup name states the general category covered by that group, the second, a subcategory of that general category, and so on.

For instance, the newsgroups sci.chem and sci.math are scientifically-oriented groups which are dedicated to chemistry and mathematics, respectively. soc.culture.indian is sociologically-oriented group devoted to the culture of India, and so on.
