  1. Utilizing the Internet Using Internet Explorer to access Internet resources

  2. The Internet • The Internet has become as widely used as any technology since the television. • A network of networks, the Internet is the ultimate WAN, spanning the entire globe. • With millions of host computers covering every possible topic, it pays to use the Internet efficiently to save time and money.

  3. Industrial Uses of the Internet • Most companies have websites on the Internet (more on websites later) which provide information about their products such as: • Technical specifications • Troubleshooting flowcharts • Replacement parts ordering • Tutorials

  4. Websites and web pages • A website is a location that contains information for a particular place, company, or person. • A website consists of many web pages. • A single host (or server) computer can host many websites. • A website is accessed by using its URL.

  5. URLs • URL stands for Uniform Resource Locator. • A URL is an address for a specific website. • The normal format of a URL is www.domain.suffix. • Examples are: www.espn.com, www.whitehouse.gov, www.beloit.edu

  6. Website addresses • The WWW in an address stands for World Wide Web. • The domain specifies a specific location or company, like ESPN or Beloit. • The suffix specifies whether the site is a company (.com) and educational site (.edu), a government site (.gov), military (.mil), non-profit (.org) or a network (.net).

  7. Accessing a website • To access a website, you must use a Web Browser application. • Internet Explorer and Netscape navigator are the most common. • When you open the browser, you will first see the Home Page for that computer’s default website. • A Home Page is just the initial page for the website.

  8. Accessing a website • In the Address Bar of the browser, type in the URL you wish to access and hit the Enter key. • If the URL is valid, and the website is operating, then you will see the Home Page for that website. • The next page shows the Home Page for www.dead.net

  9. An example Home Page

  10. Hypertext and hyperlinks • Websites are based on a technology called Hypertext. • Hypertext allows for a particular word, group of words, or picture to link to some other web page. • Normally Hyperlinks are underlined. For example, if you click on CST you will access the CST website.

  11. Forward and backward • It is easy to get lost when browsing websites; you click on a hyperlink and suddenly you are not where you want to be. • In the upper left corner of the Internet Explorer (IE), there are two buttons on the toolbar, a left button (back) and a forward button (forward).

  12. Forward and backward buttons

  13. Forward and backward • The Back button takes you to the previous web page you were at. • If you click the small downward arrow next to the back button, it lists many web pages you have been to in sequence so you can choose one quickly. • The Forward button allows you to reverse the Back button if necessary.

  14. Search engines • Finding information on the Internet can be daunting. • A search engine is a website designed to make finding information on the Internet easier. • In general, you type in some information, click Search (or something similar) and the search engine provides potential websites that may contain information about the query you typed.

  15. Search engines • Some popular search engines are: • www.google.com • www.ask.com • www.altavista.com • www.yahoo.com • www.dogpile.com • Since these addresses are hyperlinked above, you can try them out if you wish.

  16. Search engine queries • The success you have with search engines will depend on your ability to write good queries. • Be certain to read the instructions at the search engine you wish to use. • For example, some allow you to use normal sentences, while others prefer only chunks of text in quotes.

  17. Example queries • Some example queries for the same information; it all depends on the engine you use: • Where can I learn about volts? • “learn about volts” • Learn + volts • Learn or train or tutor and volts or electricity
