This article is from the Amiga Networking FAQ, by Richard Norman with numerous contributions by others.
Two examples of WAN's which use entirely different techniques, but whose services
are overlapping. There are interconnections and usenet traffic can and does
travel across the internet, but for the most part they are separate networks.
Also the Internet is actually many networks which are interconnected on a world
wide scale.
Usenet utilizes the phone system and temporary links to move information between
systems. It uses a system of store and forward. It stores up outgoing messages.
Then on a periodic basis makes a connection to a specific computer and forwards
the messages, and downloads any incoming messages then breaks the connection. A
popular usenet protocol is UUCP and the most popular application is NEWS which
is also now on the Internet.
The Internet on the other hand is mostly a shared backbone which is always
available between the primary systems. The usenet does not use dynamic routers.
An Internet router is always on and always connected to other routers. An
internet router immediately determines an incoming message's next destination and
immediately sends it on its way. A usenet "router" waits until the next scheduled
connection time before sending the message on its way. The most common protocol
on the Internet is TCP-IP and one of the most popular applications is Mosaic
which relies heavily on FTP and Gopher.
Q) How do I connect?
There are three basic ways with more to come hopefully.
A) modem to modem
B) modem to commercial service
C) direct to WAN or ISP provider
Or if the company where you work has a network, you should contact your local
network administrator about the procedures for getting network access at your
company.
Other modes of free access are available through schools, universities, libraries,
and government programs. Ask around your local user groups, etc.
