Hi Tina and Anne

A note below on World wide web and the Internet and the difference copied
from a website... Also a link at the end to help you practice your samples.

Many people use the terms Internet and World Wide Web (aka. the Web)
interchangeably, but in fact the two terms are not synonymous. The Internet
and the Web are two separate but related things.

What is The Internet?

The Internet <http://www.webopedia.com/TERM/I/Internet.html>  is a massive
network <http://www.webopedia.com/TERM/N/network.html>  of networks, a
networking infrastructure. It connects millions of computers together
globally, forming a network in which any computer can communicate with any
other computer as long as they are both connected to the Internet.
Information that travels over the Internet does so via a variety of
languages known as protocols <http://www.webopedia.com/TERM/P/protocol.html>

What is The Web (World Wide Web)?

The World Wide Web <http://www.webopedia.com/TERM/W/World_Wide_Web.html> ,
or simply Web, is a way of accessing information over the medium of the
Internet. It is an information-sharing model that is built on top of the
Internet. The Web uses the HTTP protocol, only one of the languages spoken
over the Internet, to transmit data. Web services, which use HTTP to allow
applications to communicate in order to exchange business logic, use the the
Web to share information. The Web also utilizes browsers
<http://www.webopedia.com/TERM/B/browser.html> , such as Internet Explorer
<http://www.webopedia.com/TERM/I/Internet_Explorer.html>  or Firefox
<http://www.webopedia.com/TERM/F/Firefox.html> , to access Web documents
called Web pages <http://www.webopedia.com/TERM/W/web_page.html>  that are
linked to each other via hyperlinks
<http://www.webopedia.com/TERM/H/hyperlink.html> . Web documents also
contain graphics, sounds, text and video.


The Web is just one of the ways that information can be disseminated over
the Internet. The Internet, not the Web, is also used for e-mail
<http://www.webopedia.com/TERM/E/e_mail.html> , which relies on SMTP
<http://www.webopedia.com/TERM/S/SMTP.html> , Usenet
<http://www.webopedia.com/TERM/U/USENET.html>  news groups, instant
messaging <http://www.webopedia.com/TERM/I/instant_messaging.html>  and FTP
<http://www.webopedia.com/TERM/F/FTP.html> . So the Web is just a portion of
the Internet, albeit a large portion, but the two terms are not synonymous
and should not be confused.
