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.

"sci" Discussions marked by special and usually practical

knowledge, relating to research in or application of the established sciences.

"misc" Groups addressing themes not easily classified under any

of the other headings or which incorporate themes from multiple categories.

"soc" Groups primarily addressing social issues and

socializing.

"talk" Groups largely debate-oriented and tending to feature

long discussions without resolution and without appreciable amounts of generally useful information.

"news" Groups concerned with the news network and software

themselves.

"rec" Groups oriented towards hobbies and recreational

activities.

Also available are many "alternative" hierarchies, like:

"alt" True anarchy; anything and everything can and does

appear. Subjects include sex, and privacy.

"biz" Business-related groups

"clari" Newsgroups gatewayed from commercial news services and

other 'official' sources. (Requires payment of a fee and execution of a licence. More information by email to info@clarinet.com).

Most Netnews hosts offer both global and local conferences. Many newsgroups can be read through bulletin boards, commercial online services, or through gateways from connected hosts (like from some BITNET hosts).

A full list of available groups and conferences are normally available from hosts offering Netnews, and on NETNEWS servers. All users should subscribe to news.announce.important .

Short takes about how to get started

====================================

a computer * modem and a communications program

You must have a computer

It is not important what kind of computer you have, though you may find out that it is an advantage to have a popular one. The most common type of microcomputer today is called MS-DOS computers (or IBM PC compatibles or IBM clones).

Your computer should have enough memory for communication. This is seldom a problem. An MS-DOS computer with 256 KB RAM is enough when using popular programs like PROCOMM. Your computer does not have to be very powerful and super fast, unless you want ultra fast transfers, use a slow communications program, or a complex system of script files. If this is the case, you'll know to appreciate speed and power. You do not need a hard disk. Many do without. Not having one, however, means more work, and less room for storage of all the nice things that you may want to retrieve by modem. Personally, I want as much hard disk space as I can possibly get. When you have read the book, I guess you'll understand why. Others may want to delay the purchase of a hard disk until they can spare the money. If you can afford it, however, do it! It is a decision that you'll never regret.

You must have a modem

Some computers are always connected to a network. If this is your situation, then you probably have what you need already. The rest of us need a modem.

A modem is a small piece of equipment that is translating the internal, electrical signals of the computer to sound codes. These codes can be sent over an ordinary telephone line. You may think of it as a type of Morse alphabet. The recipient of data also needs a modem. In his case, the sound codes will have to be translated back into their original form as digital codes. When this is done, he can view text and pictures on the screen, and use the received data in other applications. You can buy modems on an expansion card for installation in your computer, or in a separate box. Often, a modem has already been built into the computer, when you buy it. Whether to buy an internal or an external modem is a question of needs: A portable computer with an internal modem is easier to bring on travels than an external modem with a modem cable and a power adapter. An external modem can serve several computers. Some of them are so compact that they fit besides your toothbrush in the toilet bag. An internal modem blocks one of your serial ports.

External modems

The options are many. The modems differ on speed, features, prices - and whether they are approved for usage in your country.

Some of them are connected to the phone line by cable. Others are connected to the handset (to the talk and listen part) by two rubber cups. We call such modems acoustic modems (or acoustic couplers). Acoustic modems are useful where connecting other modems to the telephone is difficult. The bad news is that you'll get more noise on the line. Acoustic modems can therefore not be recommended for use in other cases.

Asynchronous or synchronous modems?

Formerly, data communication was done by sending job commands to a mainframe computer, and having the result returned in one batch. The modems were called synchronous. Such modems (and computers) are still in use in some large corporations.

Most of today's online services are based on an interactive dialog between the user and the remote computer. The user enters a command, for example a letter or a number in a menu, and the result is returned almost immediately. The modems used for such work are called asynchronous (See "Explanation
