As the previous example shows, newsgroups names are hierarchical and resemble domain names. One difference is that newsgroup names become more specific as you read from left to right. Here are some examples; the newsreader you choose will have a command to tell you which groups are received at your site:
Table 1: Newsgroups in Usenet.
One of the first things you will want to do when you subscribe to a newsgroup is find its list of frequently asked questions ( FAQ). Almost every group has an FAQ list which is maintained by a volunteer. FAQ lists are posted to the newsgroup about once a month, and they are also available at various sites around the network.
