SECTION 3: WORLD WIDE WEB
Key points
The following key points are covered in this section of the video. You may wish to discuss or reflect on these points after viewing this section of the programme.
• You view the World Wide Web using "browser" software; e.g. Netscape or Internet Explorer.
• If set up to do so, your browser will automatically open to your home page when you connect to the Internet. If not, you may have to open a web page yourself once you are connected.
• If your browser opens and there is no information on the screen, it is likely that you are not connected to the Internet.
• You may alter the website page which opens automatically as your home page. This can be selected through your Options of Preferences settings.
• Every page of a website has a unique address. This is called the URL or Universal Resource Locator.
• URLs usually begin http://www.
• If you know the URL address of a site, or of a page within a site you want to visit, type the address into the space provided and press Enter or Return.
• If you experience difficulties in accessing a site, check the address first. It has to be written exactly, in lower case with no spaces. If you have difficulties, check to ensure you have not omitted the necessary full stops, or even www.
• When you visit a website, the computer may store the site information into its memory for a short time. This is called caching. If you visit a site regularly, it is possible that your computer will default to the stored (cached) version and not the latest online version of the site. This is an issue only if the website has constantly changing information; e.g. a new site or the New Zealand Education Gazette. To be sure you are viewing the most recent online version, click on Reload or Refresh buttons.
• Websites and web pages are linked to one another by hyperlinks or hypertext. Clicking on these will take you to another page within the site or possibly to a completely new website. Navigating in this way is called surfing the web.
• Web pages may require you to scroll down to view them. Navigation icons are often shown at the bottom of web pages.
• You can backtrack through the pages you have visited by using the Back button on the browser. This will take you back one page at a time towards your starting point.
• Clicking on the Home button will return you to the page which has been selected as your home page.
• The History or Go button provides a list of previously visited websites. Using this can be a short-cut returning to a particular site.
• By clicking on the Bookmarks or Favourites button, you will be provided with the means to capture the address of the site you are currently visiting. The bookmarked address will be retained within your computer's memory even when you turn off the computer.
