On-line discussion groups are fun, educational, and lifesaving. New ideas and experiences are being shared every moment of the day by doctors, teachers, scientists, engineers, policemen, lawyers, religious leaders and anyone else that needs to find knowledge or has knowledge to share. With Usenet newsgroups the latest developments in every field imaginable are now at our fingertips with the click of a mouse. Anyone with a computer and a modem can gain access to the latest developments in their field of choice as fast as the leading experts in the field. A Usenet newsgroup is a collection of messages, posted by interested parties, and responses to them.
All messages pertain to one particular subject.
Newsgroup messages are sent through news servers worldwide. There is no central location. Web browsers like Netscape s Navigator and Microsoft s Internet Explorer have built-in support for protocols like internet discussions groups become.
