Usenet (User’s Network)

Usenet is an independent network of thousands of servers around the world and has been the most popular medium for information and file exchange for many years. It is also a global discussion system that develops and consists of UUCP networks on the Internet.

The Usenet network can be expressed as a prehistoric system compared to PHP, XML, or HTML. Usenet was invented in 1979 and WWW in 1990.

The emergence of this environment dates back to the time when the first computers appeared and the first interconnection networks appeared. The first network was developed by the US prior to Usenet’s advent and they named it Darpa instead of Arpanet.

Arpanet was able to join supercomputer networks, thanks to the NCP protocol, and this network was limited to US government research centers only. It was initiated by the Ministry of Defense in the ARPA program, and only by academic departments.

The first machine connected to the Arpanet network was at UCLA University in 1969, and it was organized in mailing lists with a central control deciding what to publish for each list. In 1975, thanks to the Internet project, TCP/IP was developed, where messages were split into packets and reconfigured at the target.

The Usenet network arose from the idea of two graduate students Tom Truscott and Jim Ellis at Duke University in North Carolina in 1979 to communicate with the rest of the Unix community. After Steve Bellovin met with other students and evaluated this idea, Usenet was created as an alternative to Arpanet.

In the following years, Arpanet replaced Usenet as the dominant network, creating the popular Internet network today. However, Usenet survives as it was in its early days and offers access to a large number of uncensored information and files.


Users using this network can read or send messages by joining different newsgroups arranged in a hierarchical fashion. When a user subscribes to a newsgroup, the news client software edits and manages the series of articles the user is reading.

In many newsgroups, most articles are replies to someone else, and the set of articles that can be traced back to the starter article is called a chain. Also, the latest versions show articles organized into headlines and subheadings to make it easy to find discussions in a newsgroup.

Since each server creates its own group, it is difficult to determine the total number of groups. Usenet consists of data updated and disseminated around the world as it relates to articles published in each or more groups. The articles are in plain text with other restrictions and do not use the MIME extension.

Each server determines the lifetime of the articles according to their titles, size, and publication date. Articles are sometimes used to include binary files encoded in text format using algorithms such as UUEncode, Base64, or yEncode.

A large number of users and groups have made Usenet the world’s largest information exchange and discussion network, thanks to the scarcity of necessary resources, speed, anonymity, and paid or free access.


Usenet has not censored IP addresses or any information since 1979, and confidentiality is high as there are no logs. The secured files allow simultaneous connection to server farms.

Since the development of this communication environment, it has been the world’s largest data storage center. Terabytes of data are added almost every day. It is also considered the most downloaded platform thanks to its millions of files and software databases.

It also led to the emergence and popularity of widely recognized concepts such as spam, and the first bulk spam appeared on January 18, 1994, and a specific message was sent to many groups.

As a result, the Usenet communication environment is completely free and accessible to anyone.
