<strong>The</strong> <strong>Online</strong> <strong>World</strong>: What is it? http://home.eunet.no/~presno/bok/2.html<br />

In May 1991, Kidlink arranged a full day chat between kids from all over the<br />

world. Line, a 12 year old Norwegian girl, started the day talking with Japanese kids at<br />

the Nishimachi and Kanto International School in Tokyo. When her computer was<br />

switched off late that night, she was having an intense exchange with children in North<br />

America.<br />

<strong>The</strong> chats took place on various online services and networks, including Internet<br />

Relay Chat (IRC), BITNET's Relay Chat, Cleveland Free Net (USA, now defunct),<br />

TWICS in Tokyo, the global network Tymnet, and the Education Forum on<br />

CompuServe.<br />

<strong>The</strong> discussions had no moderator. This made the meetings chaotic. but the kids<br />

enjoyed it! One line messages shot back and forth over the continents conveying intense<br />

simultaneous conversations, occasionally disrupted by exclamations and requests for<br />

technical help.<br />

Speed is a problem when chatting. It takes a lot of time as most users are<br />

slow typists.<br />

If an individual message spans more than one line, there is always a risk that it will be<br />

split up by lines coming from others. It takes practice to understand what goes on.<br />

Users of SciLink (Canada) use a method they call 'semi sync chat'. <strong>The</strong> trick is to<br />

use ordinary batch mode conferences for chatting. Instead of calling up, reading and<br />

sending mail and then log out, they stay online waiting for new messages to arrive. This<br />

approach allows the entry of multiple line messages without the risk of them being<br />

broken up by other messages. <strong>The</strong> flow of the discussion is often better, and each<br />

person's entries easier to understand.<br />

File transfers<br />

Millions of files are transferred to and from the online services each day: Books and<br />

articles, technical reports, graphics pictures, files of digitized music, weather reports, and<br />

much more. Retrieval of free or inexpensive software is a very popular service on the<br />

Internet, and other free services.<br />

In February 1994, users downloaded 105 megabytes' worth of public domain and<br />

shareware programs from of my BBS, though it only one phone line and a 9,600 bits/s<br />

modem. Add to this the megabytes being downloaded from hundreds of thousands of<br />

other bulletin boards. <strong>The</strong> number is staggering.<br />

If you want to download software, check out appendix 3 for additional<br />

information.<br />

Downloading is simple. Just connect to a service, order transfer of a given file, select a<br />

file transfer protocol (like XMODEM), and the file comes to you through the phone line.<br />

On the Internet, you may just locate the file with your browser, and then simply<br />

click on the file name to transfer it. Often, files are also transferred using a command<br />

called FTP (File Transfer Protocol), or by using special computer programs for file<br />

transfers.<br />

If you cannot receive files as explained above, check if you can have files<br />

sent by email using a technique called UUENCODEing. Here, the file is<br />

converted before transfer into a format that can be sent as ordinary mail<br />

(into a seven bits, even character code).<br />

When the file arrives in your mailbox, you 'read' it as an ordinary<br />

message and store the codes in a work file on your disk. Finally, you<br />

decode the file using a special utility program (often called UUDECODE).<br />

Read more about this in Chapter 12.<br />

Conferences and discussions<br />

<strong>Online</strong> conferences have many things in common with traditional face to face<br />

conferences and discussions. <strong>The</strong> main difference is that the participants do not<br />
