What does www stand for?

The web is a huge collection of electronic pages filled with written information, graphics, sound and video clips.

What exactly is the Web?

• To Inform

• To Persuade

• To Promote (Advertise or Sell)

• To Entertain

M-m-m Remind You of Something?

• To Inform

• To Persuade

• To Promote (Advertise or Sell)

• To Entertain

Now without peeking, you tell me—

The www is made up of millions of these web sites

all connected by links

A Web site has links that can take the user to other Web pages . . .

Within the same site—these are called “internal links”.

Or the links can take us to pages at other Web sites—these are called

“external links”.

ALL ARE CALLED

HYPERTEXT LINKS

The Universal Resource Locator (URL) tells us the address of a Web

site.Example:

www.dickinson.k12.nd.us/berg/

Is the URL for Berg Elementary’s “Home Page”

Question: What is a Home Page?

The Definition of a Home Page is:

www.dickinson.k12.nd.us/berg/

The main page of a Web site. It usually has an index telling what is

contained on the site.

The Definition Of A

Hyperlink or Hypertext Link:

•Highlighted words or graphics found on Web pages.

•A user can jump to a new page on the Web site by clicking on the link.

•Sometimes they even take you to a new Web site altogether!

What’s a Link?

Example:

www.dickinson.k12.nd.us/berg/

Is the URL for Berg Elementary’s Home Page

This is a Link

The Universal Resource Locator (URL) tells us the address of a Web site.

Let’s take a closer look at the URL . . .

Again, what does URL stand for?

Yes, universal resource locator

Basically, what is an URL?

It’s the address for a Web page

URL’s can tell us important things about Web sites.

By studying the domain of a Web site, you may be able to tell what a Web site is about and also whether it is reliable or not.

“What’s a domain?” –you may ask.

www.revolutionarywar.cloudworth.com/heroes-generals.phpwww.revolutionarywar.cloudworth.com/heroes-generals.php

Let’s look at an example of an URL.

The “Domain Name” is the part of a web address that follows the “www.”

The Top Level Domain is the part of the URL that indicates the type of Web site. Some examples of this

are: .edu, .com, .gov, .org, and .mil 

www.revolutionarywar.cloudworth.com/heroes-generals.php

Okay, we’ve gone over lots of stuff about links and URLs. We know that links connect us to different Web pages. But what about the Web pages? Are they just floating out there somewhere? Where are they so that we are able to link to them???

The answer is that there is a special kind of software (and also special computers) that store Web pages and provide them to computers that request the information.

These are called servers or “Web servers”.

Now here’s another question for you.

What is it—on your computer—that let’s you connect to the Internet?

The answer is—a “Web browser”.

The name for the software that allows us to connect to a web server is called a “Web browser”.

There are many different Web browsers

Some of the most common Web browsers are Microsoft Internet Explorer, Netscape Navigator, and Safari.

Web browsers allow us to go to one of the various search engines to search for information on the web.

So let’s talk about this—What is a “search engine”?

Definition: A program used to search for information on the World Wide Web.

Some of the most common search engines today are:

We’ve covered a lot of information. Now you need to

put it to use!
