1. What is the Internet?
• The Web is only part of the Internet
• The Internet is a computer network connecting millions of
computers all over the world. It provides communications to
governments, businesses, universities, schools and homes
(Davies, 1999).

2. How to find materials on the
Web
• Search engines: such as Google, which is currently the most
popular search engine on the Web, key in a word or key
phrase in any language, and the search engine will find it.
• When searching, the most important thing is to hit on the
keywords that will bring up the information you are looking
for.
• For example, you may be looking for lyrics of French songs.
The keywords are lyrics French songs. These three keywords
will probably find all the sites that contain these keywords,
but not necessarily in that order.

• Google is a very efficient search engine.
• You can also search for images and news items in the world's
press by clicking on the Images or the News tab and Maps.
• You can also use Google as a simple concordancer to search
for collocations that you are unsure about. Is it possible, for
example, to say "a metal wood"?

Wikis
• A wiki is essentially a series
of interlinked collaborative
Web pages that can be
edited and added to by a
group of people - an online
resource for which content
can be created collectively.
It allows anyone who views
the wiki to add to or edit the
existing content as if they
were adding to or editing,
e.g. Wikipedia.
