  4. The Internet : Mother of all Networks History What is the Internet? • 1970’s US DOD (Dept of Def) developed 1st version of the Internet: DARPA Network (ARPAnet) • Used for quick communication among researchers in various locations. • 1980 NSF funds high-speed connection among university centers based on the ARPAnet structure • Infrastructure • A network of networks. Internet “between or among networks • Networks connect computers to allow users to share resources and exchange information easily. • A way for people in network sites ALL OVER THE WORLD to communicate with each other as though they were on the same local area network.

  5. Connected in one big network[underwater data cables] SANKARSINGH,C TECH1001

  6. The World Wide Web:An Internet Service What is the World Wide Web • an Internet service that links sites around the world through hypertextdocuments. • subset of the Internet system • refers to the entire “universe” of network-accessible information • has a body of software, set of protocols and conventions • We use a program called a WEB BROWSER to bring up one of these hypertext/media-based documents. • Hypermedia [linked media] allow us to “travel” from site to site. • What browsers do you know of? Which ones do you use? SANKARSINGH,C TECH1001

  7. Navigation Browser Uniform Resource Locator • Gateway to the internet • Software application programme installed on your computer/device to allow you to “surf.” • Internet protocols allow computers to communicate with each other [ regardless of macs, windows, etc.] • An important protocol is HOW WE LIST WEBSITE ADDRESSES • Every website has an address • URLs are Internet addresses SANKARSINGH,C TECH1001

  8. Navigation Web Addresses Activity 1 (7 mins) • http://hypertext transfer protocol • www.world wide web • nationalgeographicname of site • .comdomain designator • Find one website with the following domain designations: • .org (organization) • .gov (government agency) • .tt (country) • .com (business) • .edu (educational) • .net (network) SANKARSINGH,C TECH1001

  10. Navigation-Organization • Search Engines are programs that help us to locate things: • The address bar in the Google’s Chrome browser features a built-in search engine. Other browsers may follow suit. • Browsers allow us to Bookmark interesting sites that we may wish to re-visit/access more easily. Web services like Diigo also let us do this. SANKARSINGH,C TECH1001

  11. Navigation-Research-Evaluation Research & Evaluation Information located, now what? • Information contained on a website must be evaluated. • RelevancyIs the info related to the prob?Does it contribute to the intention of the search?Does it provide explanation? Examples? Alternative perspectives? • Credibility SANKARSINGH,C TECH1001

  12. Evaluate = Read critically Who provided this information? Does the site author have authority in that field? If the site is published by an organization, do you recognize it? Is it clear when the site was developed and last updated? Is there a bibliography/resource list included? Is the content factual/opinion? Theoretical or evidence-based? Fact or fiction? http://zapatopi.net/treeoctopus/Use the Criteria for Evaluating Website Content in your text (Chap 7) to evaluate the site above. SANKARSINGH,C TECH1001
