EVOLUTION OF THE INTERNET (pg. 299) LECTURE NOTES Remind students that the Internet is a worldwide collection of linked networks that is used for personal and commercial communications and for information exchange. It consists of thousands of interconnected networks that are accessed by millions of people daily. Briefly describe the evolution of the Internet from 1969 to the present. Mention that, despite its success in academia, the Internet went virtually unnoticed by the general public and business community for over two decades; two reasons—it was hard to use and slow. Discuss the history of the World Wide Web. Use Figure 8-1 to illustrate the differences between early Internet usage and today’s Web pages. Mention that Internet2 is a consortium working in conjunction with industry and the government to develop and implement improvements for tomorrow’s Internet. Be sure students understand that Internet2 is not a physical network to replace the existing Internet—just a consortium working to improve the Internet. Cover the individuals and groups that comprise the Internet community, such as users, Internet service providers (ISPs) and Web Services, Internet content providers, application service providers (ASPs), infrastructure companies, hardware and software companies, and the government. Briefly run through the three myths featured in the section. Be sure to stress that no one person or organization is in charge of the Internet as a whole. Instead, each person or organization permanently connected to the Internet manages their respective part of the Internet.

CLASSROOM ACTIVITIES 1. Class Discussion: Ask students to presume they have home Internet access through a free ISP, such as NetZero or Juno. Have the students brainstorm as to how it is possible that the ISP can offer individuals free Internet access, even if some are just for 10 hours per month or so. Who pays for the students’ Internet access? What is the tradeoff? Would students prefer to use a free or fee-based ISP? Why? 2. Quick Quiz: 1.

(Answer: Internet service provider (ISP)) GETTING SET UP TO USE THE INTERNET (pg. 305) LECTURE NOTES Explain that getting set up to use the Internet usually involves three decisions: determining the type of device to be used, selecting the type of connection and Internet access desired, and then deciding on the Internet service provider to be used. Once these have been determined, then your PC can be set up. Discuss the various types of devices that can be used to access the Internet. Explain that Internet connections can be always-on (direct) or dial-up. Discuss the various options for Internet connections and their speed, and other characteristics. Discuss some considerations to keep in mind when selecting an ISP. Mention that after selecting an ISP, there are various steps that need to be taken (such as installing hardware and/or software) to set up a computer to work with that ISP. BOXES Inside the Industry: ISP Bandwidth Limits (pg. 306) FIGURES Figure 8-5, Figure 8-6, Figure 8-7, Figure 8-8, Figure 8-9, Figure 8-10 Understanding Computers: Today and Tomorrow, 14th Edition, Instructor’s Manual 4 of 12 TEACHER TIP Refer your students to Figure 8-7 for a comparison of different types of home Internet connection options and Figure 8-6 for a comparison of speed.

Ask students to describe the kind of ISP they would recommend to get Grandma up and running. Record suggestions on an overhead or on the board. What kind of connection would they recommend (dial-up or always-on)? Grandma is especially concerned about security, since she has heard a lot about viruses and identity theft. How would you help her get over her anxieties about these things? Debate simplicity versus lack of features, and sophistication versus information overload. How would their recommendations change if their boss asked for a suggestion for an ISP? 2. Quick Quiz: 1.

Be sure to discuss how to evaluate the search results for appropriateness Explain how to properly cite the Internet resources they use to avoid plagiarizing information. Some sample citations are shown in Figure 8-16. If students will be submitting research papers for this course, this would be a good time to explain the citation requirements you will expect of them for both online and offline material.
