Usenet Usenet is a collection of user submitted notes or messages on various subjects that are posted to servers on a worldwide network. Each subject collecting posted notes is known as a newsgroup. There are thousands of newsgroups and it is possible for you to form a new one to add to the collection. Usenet servers can be accessed by using a Usenet browser like supernova or newsgroups.
Internet relay chat (irc) Internet relay chat is a application layer protocol that facilitates communication in the form of text. The chat process works on a client/server networking model. IRC clients are computer programs that a user can install on their system. These clients communicate with chat servers to transfer messages to other clients. IRC is mainly designed for group communication via private messages as well as chat and data transfer, including file sharing. Some examples of IRC servers are opera net, free node and EFnet
