Usenet as a service doesn’t necessarily function on its own. Files and information need to be posted in Usenet by users and exchanged through peering. These would be indexing options allowing Usenet’s environment to thrive and function.
Usenet is based off of the trading and downloading of files and discussions. Usenet customers can share recipes, games, and software by using newsgroups. These pieces of information don’t appear on the service out of thin air. Users have to post these messages or files in order for them to show up on any server around the country. Something posted in New York City may end up in Portland within a matter of days or even a matter of minutes through peering.
Peering is a peer to peer network setup by Usenet providers across the country. These are machine set up to constantly trade newsgroup articles and information to make sure everybody is on the same page and has the same information on the servers. Without peering and this process, Usenet providers would be stuck with only what their users post and provide. Usenet providers contact other providers and set up their peering computers to communicate constantly, trading files and information to provide better retention and completion. These are machines that the public has no interaction with.
Without user posts and a peering technique, Usenet would fail. Information needs to be provided on a daily basis to keep other users interested in the service. Usenet has been around for many years and will be for many more with the help of many people around the world.
