What are the
Internet and the WWW?
The Internet is a global digital
infrastructure that connects millions of computers. It is a global internetwork
(network of networks), with cross platform compatibility, using the Internet
Protocol (IP) to communicate between computers.
It uses
existing public telephone and communication (including satellites) networks to
relay data between networks using routers.
The fastest
growing part of the Internet is the World Wide Web. Other parts of
the Internet include services
such as gopher, telnet and ftp.
The World Wide Web (WWW) is a uniform method
of accessing and retrieving information on the Internet.
This
information is almost always retrieved using the HyperTextTransfer Protocol
(HTTP). In fact HTTP has been in use by the World Wide Web since 1990, and its
use has increased steadily over the years. Today there are millions of Web
sites on the World Wide Web, all of them using HTTP.
Information on
the World Wide Web is stored in a hierarchical fashion, using hypertext and hypermedia.
·
What are the components of a URL?
URL stands for Uniform Resource Locator. Simply
stated, a URL is a Web site's complete "address" on the vast map of
the Internet. Just as your home address is made up of several components--house
number, street, city, state, zip code--the URL for a World Wide Web document
has four components, each separated by a slash (/). These components are
illustrated in the chart below.
|
1. The prefix http:// |
2. The name of the host computer |
3. The directory path on the host computer |
4. The filename itself |
|
http:// |
www.mcdougallittell.com/ |
lit/ |
idiom.htm |
|
http stands for hypertext transfer
protocol. Followed by a colon and two slashes, this prefix tells your
computer that the document you seek is found on the Web. |
Also known as the domain name, this
is the part of the address that identifies a specific computer on the
Internet. The example identifies McDougal Littell's (mcdougallittell) commercial
(.com) site on the World Wide Web (www). |
The third component identifies the directory.
Some URLs contain several subdirectories, separated by slashes. The example
identifies a directory on the McDougal Littell site called Literature
(lit). |
At last you arrive at the desired file,
or Web page. The example calls up the idiom file (idiom.htm), which is
the introductory page to an activity for students called Idiom of the Week. |
All Web browsers display a Web site's URL in
a rectangular box at the top of the screen (see if you can find the URL in figure 1).
As you navigate the Web you can see how the URL changes. Or, type in the URL
yourself to take you where you want to go.
·
What is the
difference between the Internet and the WWW?
Many people use the terms Internet
and World Wide Web interchangeably. This is actually incorrect. While
the Internet links computers so they can communicate, the Web is really the
substance of that communication. A document on the Web is called a Web page
and a collection of pages is a Web site. The development of the World
Wide Web has led to the growing popularity of the Internet.
·
What is a web browser?
Web browsers, such as Netscape Navigator,
Microsoft Internet Explorer, and Mosaic, are software programs that help you
navigate the Web and access text, graphics, hyperlinks, audio, video, and other
multimedia. Browsers work by "translating" or "interpreting"
hypertext markup language
(HTML)--the code embedded in Web pages that tells them how to look.
Browsers read this code and display the Web page accordingly.
Below you can see the navigational features
of Netscape Navigator. Navigational buttons such as back, forward, home, and
print allow you to edit, send, and print documents from the Web with
ease.
·
What are the SAISD rules for using the Internet?

computers allow students access to the Internet. Students develop electronic
information research skills using these resources which are fundamental skills
for the preparation of citizens and future employees. The District goal is to
