UUCP —— UUCP (UNIX to UNIX Copy) is a protocol, a set of files and a set of commands to copy files from one UNIX computer to another. This copying procedure is the core of the UUCP network, a loose association of systems all communicating with the UUCP protocol. UNIX computers can participate in the UUCP network (using leased line or dial-up) through any other UNIX host. The network now also has many MS-DOS and other hosts, and consisted of 16,300 hosts in January 1993 (source: UUCP map) serving more than 489,000 users. The UUCP network is based on two systems connecting to each other at specific intervals, and executing any work scheduled for either of them. For example, the system Oregano calls the system Basil once every two hours. If there's mail waiting for Oregano, Basil will send it at that time. Likewise, Oregano will at that time send any mail waiting for Basil. There are databases with connectivity information (UUCP maps), and programs (pathalias) that will help you decide the correct routing of messages. However, many UUCP hosts are not registered in the UUCP map. EUNET is a UUCP based network in Europe. JUNET is an equivalent network in Japan. There are many gateway machines that exchange mail between UUCP and the Internet. Among these, UUNET.UU.NET is among the most frequently used.

Usenet ——— Usenet, Netnews, or just "News" are common terms for a large many-to-many conferencing (only) system distributed through UUCP, Internet, FidoNet, and BITNET. This grassroots driven "network" has grown out of the global university and research domains. It is a service rather than a real network. It is not an organization, and has no central authority. Usenet's newsgroups are carried by over 69,000 host computers in five continents, and has over 1,991,000 users (source: Brian Reid, 1993). Many of these hosts have access to the Internet. The European portion of Usenet is called EUNET (European Unix NET). The local administrator of each individual node in the network decides what newsgroups to receive and make available to its users. Few systems offer access to all of them. NetNews is organized in groups of 'conferences'. Each of these classifications is organized into groups and subgroups according to topic. As of June 1, 1993, there were 4500 newsgroups and 2500 regional newsgroups. Several sites are carrying over 2600 topics. The groups distributed worldwide are divided into seven broad classifications:

"comp" Topics of interest to both computer professionals and
hobbyists, including topics in computer science, software
source, and information on hardware and software systems.
