Lesson+2

To view the information at a Web site, both a Web browser and a Uniform Resource Locator **(URL)** are needed. A Web **browser** is software that displays the graphics and text of a specified site. Some common web browsers are Microsoft's Internet Explorer, AOL's Netscape Navigator, or Apple's Safari. Each of these browsers is available from their web site as a free download. The URL is a special kind of address that tells the Web browser what site to go to. For example, if we want to access today’s news at Canadian Broadcasting Corporation’s (CBC) Web site we need to know the address: //**http://www.cbc.ca**//
 * Navigating The Web**

The first part of the address,** http**, is the** protocol **which is used to transfer data over the** Internet**. There are a number of different protocols, but we will discuss only the http protocol which stands for** Hyper Text Terminal Protocol**. The two slashes following the colon indicate that what follows is an Internet address, in this case**// www.cbc.ca//**. The**// www //**indicates that the address is on the World Wide Web,**// cbc //**is the host name, and**// ca //**is a** domain **identifier that indicates a commercial organization. Note that URL addresses do not contain spaces.

Most** web sites **are divided into** web pages **with one page designated as the** home page**. The home page often contains links to other pages at that site and can contain links to other Web sites. These links, called hyperlinks, appear as underlined or colored words or as a special graphic or button on the page. Clicking on a** hyperlink **displays a different Web page or part of the current page if it is a long one. The newly displayed page can also contain hyperlinks. Clicking on hyperlinks to go from Web site to Web site is called surfing the Web. For example, at the CBC site, clicking on the**// sports //hyperlink takes us from the home page to a page containing sports news. From the sports page we could click on a hyperlink that takes us to the Web site of the movie studio producing our selected movie.//

Browsers ** Open your browser, and mouse over each of the buttons below in order to see what it is called. Then, click on each button to see what it does! Once you have finished create a table, similar to the one below: Bookmarks or Favorites After we have added the page to our list of bookmarks, we can return to it at any time by opening the bookmark/favorites menu and clicking on the page. Adding interesting pages to our Bookmark list makes it much easier to return to those pages later.

 * This diagram is called a site map. It shows us several things about this web site.
 * 1) There are five web pages in total in this web site.*The page on the top called index.html is the home page.*The arrows represent hyperlinks to the four pages beneath the home page.// ||
 * As was mentioned above, the web** browser **a critical component of browsing the Internet. In order to efficiently browse the web, lets look at the most common features of a browser to determine how they can help you.

 * As you know, the key to navigating the World Wide Web is in the site addresses. These are the locations on the Information Superhighway. In time you will of course find sites that you want to return to. Instead of having to type the url every time that you want to visit a page, you can save the pages location by adding it to your collection of bookmarks **or** favorites**.[[image:http://www.saskschools.ca/curr_content/info10/module20/images/browser/favorites.gif width="73" height="19"]] To do this, click the favorites button, and then click add to favorites. As you can see, in here you can even create folders and organize your favorites for easier access! || [[image:http://www.saskschools.ca/curr_content/info10/module20/images/mybookmarks.gif width="40" height="40" align="left" link="http://www.mybookmarks.com/"]]Wanna take your bookmarks with you where ever you go? create a free account for your self at [|www.mybookmarks.com] ||
