The Online World by Odd de Presno (find a book to read txt) 📕

participating in what You happen to be interested in. Today's communications technology lets us participate in networks in other countries at a very low cost. Many describe it as participation "beyond time and space." Write a message and send it to a person in your network. It arrives in his/her "mailbox" within minutes (sometimes seconds) and stays there until the recipient wants to read it. This built-in ability to send messages to other people's electronic mailboxes reduces the power that time and geographical distances have over our lives. A friend in a remote country gets out of bed nine hours after you, but keeps going well into what, for you, is the next morning. No problem. You can send letters when you're awake and receive replies when you're asleep. You can pick up and read your friend's messages the next day or whenever you feel like doing it. That is how two people as far apart as Arendal, Norway and Beijing, China could be involved in the development of this book. Sometimes "real time" discussions are important. Consider the following example. CompuServe has a Diabetes Forum. You can call there any time, day or night, seven days a week. Whenever you feel like it. You will always find someone to chat with who understands and shares your problems. Real-time chatting may become expensive, but you are free to decide your level of involvement. If you think that $10 spent is enough, then just stop there.

What is the point?

Thousands of commercial and noncommercial online services offer over 5,000 online databases. These infobases are repositories of electronic information. They contain full-text and reference books, magazines, newspapers, radio and TV shows, reports, and more.

In 1992, BiblioData (USA) found that around 4,000 titles (i.e., magazines, newspapers, etc.) were available online in full-text. You will find facts and figures about almost anything in the online world. The world has over 100,000 public bulletin board systems (1993). Most are small information centers, running on personal computers using a simple computer program and modems. People call in to read messages and information, retrieve free software, or just to have a good time. Most BBSes are free. Some charge a small annual fee. The largest board has 213 telephone lines, seven gigabytes of storage for letters, conferences, computer programs, and more (1993). Mind you, 7 gigabytes is a lot. It is equivalent to more than 7,000,000,000 characters, or a whopping 12,000 copies of this book! The entrepreneur sees the online world as a new, profitable playground. Many of them have made it their profession to search for information for others, and they earn a good living doing so. Others advertise and sell products and services by modem. Some set up their own online services to sell knowledge and know- how, be it of aqua culture, wine production, marketing, or about the petroleum offshore market. In business, it pays to be one step ahead of the competition. Early warnings of customers' needs, competitors' moves, and emerging opportunities can be turned into fortunes. It can reduce potential losses and help develop businesses in more profitable directions. Turn this to your advantage. Build your own early warning system that monitors online information sources and networks.

Have fun

The online world has an abundance of joke clubs, dramatic adventure games with multiple players, and large archives filled with computer game software. You can transfer these programs to your personal computer and be ready to play in minutes.

Others may feel more entertained when things get "interesting." Surely, those calling Moscow in August 1991 for news about the coup must have had a strange sensation in the stomach. Some online users react quickly when dramatic events occur. They go online to read the news directly from the wires, from Associated Press, TASS, Reuters, Xinhua Press, Kyodo News and others. Usually, the online news is coming directly to you from the journalists' keyboards. Often, you heard it here first. Other people prefer to socialize. They meet in online "meeting places" to debate everything from Africa and the administration of kindergartens to poetry, LISP programming and compressed video for multimedia applications. It has been claimed that increased use of online networking in a country can effect social changes within politics, economics, communication and science. It can support democratic tendencies, the transition to a market economy, the formation and support of businesses, the spreading of interpersonal and mass communication, the forging of invisible colleges among scientists, and breaking-up of traditional and closed information systems developed in some societies. No matter whether your application is useful or just a pastime, online services queue up to help give your life a better content. Some people fear that language might be a problem, and in particular if English is not their first language. Don't worry. You are in the driver's seat. If something is hard to understand, just log off to study the difficult text. Take your time. Nobody is watching. Will you being member of the online world make you rich? Probably not. On the other hand, it most certainly provides the opportunities to help you achieve such a goal, no matter how you define the word "rich."

Chapter 2: The online world

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

This chapter is about the structure and contents of the online world. You will read about Bulletin Board systems, discussion lists, conferencing systems, online data bases, packet data services, and network services like FidoNet, i-Com, Infonet, and the Internet.

From papyrus to bits and bytes

Around 1500 B.C., the world's first library was established in Tell el Amaran, Egypt. Eight hundred years later, the first public library opened in Athens, Greece.

It took another two thousand years for the computer to be invented. The first known mention of a possible future online information service was printed in the Atlantic Monthly magazine in

Nine years later, the Naval Ordinance Test Station opened their online search service in California (U.S.A.) The first full-text database came six years later. MEDLARS was a bibliographic database containing references to medical literature. From now on, things started to roll at a faster pace:

In 1972, DIALOG (U.S.A.) opened their Educational Resources

Information Center and National Technical Information Service

databases for online searching. (Appendix 1 contains infor-

mation about the major online services referred to in this

book.)

In 1974, Dow Jones News/Retrieval (U.S.A.) launched a

financial information service for stock brokers.

In 1978, the first bulletin board was put into operation in

Chicago (U.S.A.).

CompuServe (U.S.A.) launched a service for home users in

The online world was born in the United States. Little happened in the rest of the world until the late 1980s. American companies and users still dominate, but they are no longer alone.

Today, we can access over 5,000 public databases. They are available from more than 500,000 online systems ("host computers") all over the world. With so many online services, it is difficult to find our way through the maze of offerings. This book therefore starts with a map of the online world.

The structure and contents of the online world

The online world can be described as a cake with multiple layers, where the information sources are the bottom layer. You - the user - are the marzipan figure on the top. The online world contains the following tiers:

(1) Database producers and information providers (2) Online service companies (3) Gateways and networks (4) The services (5) The user interface (6) The data transport services (7) The User.

Database producers and information providers.

I have a bulletin board system in Norway (at +47 370 31378). My BBS is running on a small personal computer, and offers shareware and public domain software.

Anybody can call my board to have programs transferred to their personal computers by modem (see appendix 2 for how to do this). When you call this BBS to "download" a free program for to your computer's hard disk, don't expect to find one made by me. I don't write programs. All available programs have been written by others. When you call Data-Star in Switzerland, or CompuServe in the U.S. to read news, you may find some stories authored by these companies. Most of their news, however, are written by others. InfoPro Technologies delivers Russian scientific and technical articles from "Referativnyi Zurnal" through online services like Orbit, Pergamon and BRS. InfoPro is not the originator. The text has been prepared by VINITI (the Institute for scientific and technical information of the xUSSR). My BBS (the "Saltrod Horror Show"), Data-Star, NIFTY-Serve, Orbit, Pergamon, BRS, and CompuServe are online services. We call those who have provided the news and information on these services for information providers or database producers. The American news agency Associated Press is an information provider. They write the news, and sell them to online services like Dialog, CompuServe, Nexis and NewsNet. These online services let you read the news by modem. The information providers sell the right to distribute their news. Your news reading charges may be imbedded in the online service's standard access rates. Some services will ask you to pay a surcharge when reading news. Most subscribers pay US$12.80 per hour (1993) to use CompuServe at 2400 bits per second (bps). At this speed, you typically receive around 240 characters of news per second. If you access at higher speeds, you will have to pay more. CompuServe pays Associated Press part of what they earn each time you read their news. There is no surcharge for reading AP news on this service. Others charge more. To read Mid-East Business Digest through NewsNet, you pay a surcharge of US$72.00 per hour at 2400 bps (1993). Scanning newsletter headlines and conducting keyword searches are cheaper. You pay the the basic connect charge, which is US$90.00 per hour at this speed. Thus, your total cost for reading Mid-East Business Digest amounts to US$2.70 per minute. CompuServe's database service IQuest lets you search NewsNet through a gateway to find and read the same articles. Here, reading will only set you back US$21.50/hour (provided the articles are among the first hits in your search). Many information providers also distribute information through grassroots bulletin boards. The Newsbytes News Network and the USA Today newsletter services (also in full text on Dialog and Nexis) are two examples. The rates for reading the same article may therefore differ considerably depending on what online service you are using. If you are a regular reader, shop around for the best price. Information providers may have subcontractors. The Ziff-Davis service Computer Database Plus, a database with full-text articles from magazines like Datamation and Wall Street Computer Review, depends on them. Datamation pays journalists to write the articles. Ziff-Davis pays Datamation for the right to distribute the articles to CompuServe's subscribers. CompuServe pays Ziff-Davis part of what you pay when reading the text. Online services

The term "online services" refers to information services provided by computer systems, large or small, to owners of personal computers with modems.

What is offered, differ by system. It may include access to libraries of programs and
