A brief history of the Internet
The Internet and
the world wide web are not the same
The Internet is a communication
channel; It allows easy transfer of information. Sending files
eg email
Accessing files held at eg universities using 'Gophers' like
'Veronica'
Some content particularly Usenet Newsgroups
1991 Tim
Benrers-Lee created the World Wide Web with a GUI (Graphical User
Interface - images), hypertext, point and click, navigation - text,
graphics, sounds, and a potential for access to information.
Now in
2005 Usenet and email are all accessed through the WWW including of course
its own content.
So in the first place was the Internet then an easy to
use interface - The WWW
To access the WW need a computer, telephone line, modem and ISP and a
Browser.
Browsers are many; Mosaic first then Netscape, now mozilla,
Opera and predominantly Internet Explorer.
Need for a prototocol (everybody does the same)
Sites are access by
their URL which translates to
numbers.
