What is the World Wide Web?

What is the internet?


This image of the world wide web was created by The Graphics, Visualization, and Usability Center. To see this website, click on the link just before the end of this page.

We'll examine details of the Web as we go along. For now, think of it as "a unique way of linking text, images, sound, and video resources on computers connected to the Internet, the world-wide network of computer networks. With the Web you can navigate seamlessly from one computer to the next, following your own interests, exploring topics in depth, without regard to where the resource is physically located on the globe.

Typically, when you view Web information on your computer screen you'll see "pages" of formatted text with pictures and graphics. When you click on highlighted text or an icon, you link to another page or access an image, sound, or video resource. These resources may be on the same computer or on another computer located elsewhere on the Internet. Each Web page you'll see has a unique Internet address that identifies it, just as your own name, street, city, state, and ZIP code uniquely identifies you." You'll see these addresses written as http://... throughout this course. Later, we will go into detail about this topic too.

The two paragraphs above are from an article on the web entitled "The Teaching Web: A Guide to the World Wide Web for all Teachers" by Ron Owston at http://www.edu.York.cay/~rows ton/chapter.html

Navigating the Net

If you have no experience at all on the internet, please read the following brief introduction. If you need to know more about the net, please see your site facilitator or technology resource teacher.

When you open Netscape Navigator, you will see a menu bar at the top of your screen. It is the same menubar at the top of this web page, and it should look more or less like this:

This is a drawing of the Netscape page, of course it is not the "real thing"!

The "buttons" at the top will take you to other pages on the web. The first 3, Back, Forward, and Home, will take you to the previous page, next page, and back to the Netscape home page, respectively. The button called Reload will reload the current page, if it loaded incorrectly the first time. The next 4 buttons, Images, Open, Print and Find are self-explanatory. The last button, Stop, is one you should click on if the page or file you are opening seems to be taking forever, and you want to stop loading it, or if you change your mind.

The next row below the buttons in the drawing above is labeled Location, and the words that follow are the "address" or "URL" for the page you are currently on. If you want to go to another page whose address you know, delete the current address and type in a new one, and hit the Return key on your keyboard.

To search the net for information, click on the Net Search button in the second row of buttons. Then type a word or words into the box that has the flashing cursor, and hit the Return key on your keyboard or click on the Search button.

On a web page, words that are underlined and in color are usually "links". You can click on a link and it will take you to another web page. The last link below will take you back to the Connected Geometry Home Page. Or, click on the first link to visit The Graphics, Visualization, and Usability Center website:
