      The standard set of codes used on the Internet to design and view World Wide Web pages.
      Sample HTML
      <p><b>Welcome to Quipayo High School</b></p>
    • Example of a WWW Page
    • Q & A
      Q: How do you reach a Web site/page?
      All you do is tell a browser to take you to the address you want. The long way to do this is to type in the entire address “URL”.
      URL(Uniform Resource Locator) -is an address of a file or document on the Web.
    • Internet Address
      Berners-Lee created a simple coding mechanism involving a string of characters called URL that identifies the name and address of each documents available to the Web
      Tim Berners-Lee of European Particle Physics Laboratory (CERN) invented the WWW
    • Web Browser
      A browser is a computer program that enables you to view web pages and access the Internet
      Examples of browsers are: Internet Explorer (IE), Firefox, Safari, Opera, and Netscape
    • Anatomy of a URL
      Directory on the server
      Hypertext Transfer Protocol
      Address of web server
    • Different Protocols on the Net
      http://hypertext transfer protocol (WWW)
      ftp:// file transfer protocol
      gopher://gopher site
      mailto:e-mail address
      Protocol-an agreed upon set of rules that govern the exchange of information.
    • Different Domains on the Net
      .com commercial
      .net network
      .edu educational
      .org organization
      .mil military
      .gov government
    • Starting Internet Explorer
      In order to get connected to the WWW, we are going to open the Internet Explorer program. Do this now by double-clicking on the Internet Explorer icon on the desktop. Throughout this training, Internet Explorer will also be referred to as Explorer or IE.
      A screen similar to the picture below should appear:
      Address Bar and URL
    • IE Toolbars and Pulldown Menu
      • The Internet Explorer toolbar is a group of button or icons that give you easy access to your frequently used Explorer commands
      The Main Toolbar
    • Favorites (Bookmarks)
      As you use the Web, you will find sites that you want to re-visit. You do not have to write down the URL for those sites. You can use Explorer to save your favourite URLs for you in the Favourites folder. To do this, once you arrive at a site that you want to save, click on:
      1. Favorites
      2. Add to Favorites
      The term ‘Favorites’ is often used interchangeably with ‘bookmarks’; saved URLs are, in fact, better known as bookmarks.
    • Adding Favorites
    • Organizing your Favorites Collection
      To start organizing your bookmarks, select Favorites, Organize Favorites. After you do that, a new dialog window will appear.
    • You may organize your bookmarks by placing them in subfolders, renaming the bookmarks, deleting them, just as you would with your files in Windows Explorer.
    • Bookmarking on the Web
    • Links
      Links or hyperlinks are usually words or pictures in a document or Web page that connect to another document or Web page. Links are usually underlined or in a different colour than the regular text in the Web page so that it is easy to spot.
    • Scrolling
      Most Web documents contain more information than can be presented on one screen. To see the rest of the document, you use the scroll bar on the right-hand side of the window. Clicking on the downward pointing black triangle will scroll down. Clicking on the upward pointing black triangle will scroll up. You can also pick up the sliding button in the middle of the triangle buttons and reveal more of the screen that way.
    • Issues about the Internet
      Objectionable materials and predators
      Viruses, privacy and security
      Intellectual property rights
      Critical thinking skills
    • CRITICAL EVALUATIONWhy Evaluate What You Find on the Web?
      Anyone can put up a Web page
      about anything
      Many pages not kept up-to-date
      No quality control
      most sites not “peer-reviewed”
      less trustworthy than scholarly publications
      no selection guidelines for search engines
    • Web Evaluation TechniquesBefore you click to view the page...
      Look at theURL -personal page or site ?
      Domain name appropriate for the content ?edu, com, org, net, gov, ca.us, uk, etc.
      Published by an entity that makes sense ?
      News from its source?
      Advice from valid agency?
    • Web Evaluation TechniquesScan the perimeter of the page
      Can you tell who wrote it ?
      name of page author
      organization, institution, agency you recognize
      e-mail contact by itself not enough
      Credentials for the subject matter ?
      Look for links to:
      “About us” “Philosophy” “Background” “Biography”
      Is it recent or current enough ?
      Look for “last updated” date - usually at bottom
      If no links or other clues...
      truncate back the URL
    • Web Evaluation TechniquesIndicators of quality
      Sources documented
      links, footnotes, etc.
      As detailed as you expect in print publications ?
      do the links work ?
      Information retyped or forged
      why not a link to published version instead ?
      Links to other resources
      biased, slanted ?
    • Web Evaluation TechniquesWhat Do Others Say ?
      Search the URL in alexa.com
      Who links to the site? Who owns the domain?
      Type or paste the URL into the basic search box
      Traffic for top 100,000 sites
      See what links are in Google’s Similar pages
      Look up the page author in Google
    • Web Evaluation TechniquesSTEP BACK & ASK: Does it all add up ?
      Why was the page put on the Web ?
      inform with facts and data?
      explain, persuade?
      sell, entice?
      share, disclose?
      as a parody or satire?
      Is it appropriate for your purpose?
    • Internet Searching
    • Search Services
      Web Portal
      A Web portal is a single point of access to information which is
      Linked from various logically related internet based applications and
      of interest to various type of users
      Portals present information from diverse sources in a unified way. They provide an excellent way for enterprises to provide a consistent look and feel with access control and procedures for multiple applications, which otherwise would have been different entities altogether.
      Examples are Yahoo, MSN
    • Search Services
      Search Engines
      Google – www.google.com
      Yahoo! Search search.yahoo.com
      Altavista – www.altavista.com
      Hotbot – www.hotbot.com
      Excite – www.excite.com
      Ask – www.ask.com
    • Search Services
      How do search engines work?
      Search engine databases are selected and built by computer robot programs called spiders – crawling on the WWW.
      They cannot think or type a URL or use judgment to "decide" to go look something up and see what's on the web about it. (Computers are getting more sophisticated all the time, but they are still brainless.)
    • If a web page is never linked to in any other page, search engine spiders cannot find it, unless its URL is sent to the search engine companies as a request that the new page be included.
      After spiders find pages, they pass them on to another computer program for "indexing." Text, links, and other content in the page are stored in the search engine database's files so that the database can be searched by keyword and whatever more advanced approaches are offered, and the page will be found if your search matches its content.
    • Ranking of websites
      Word proximity and placement
      Popularity - a link to a page is a vote for it
      Importance - traffic, popularity of pages linking to a page
      Subject specific
      Some types of pages and links are excluded from most search engines by policy. Others are excluded because search engine spiders cannot access them. Pages that are excluded are referred to as the "Invisible Web" -- what you don't see in search engine results.
