69. (p. 32) Define the parts of a URL. For browsers to connect to resources on the Internet, the address of the resources must be specified. These addresses are called uniform resource locators or URLs. All URLs have at least two basic parts. The protocol is the first part of the address and specifies which protocol (set of rules for exchanging data) to use when connecting to the Internet resources. In the example, http://www.espn.com, the protocol is http. The protocol http is used for Web traffic and is the most widely used Internet protocol. The second part of the URL is the domain name, for example www.espn.com. This indicates the specific address where the resource is located. The part of the domain name following the dot (.) is the top-level domain. It identifies the type of organization. A ".com" top-level domain indicates a commercial site.

70. (p. 33) Describe the various technologies used to provide highly interactive and animated web sites. Cascading Style Sheets (CSS) are files inserted into an HTML document that control the appearance of Web pages including layout, colors, and fonts. CSS helps to ensure that related Web pages have a consistent presentation or look. JavaScriptis a language often used within HTML documents to trigger interactive features, such as opening new browser windows and checking information entered in online forms. AJAX, an advanced use of JavaScript, is used to create interactive Web sites that respond quickly. Applets are programs that can be downloaded quickly and run by most browsers. They are used to present animation, display graphics, provide interactive games, and much more.

71. (p. 37) Briefly explain how instant messaging works. Instant messaging (IM) is an extension of e-mail that allows two or more people to contact each other via direct, live communication. To use instant messaging, you specify a list of friends and register with an instant messaging server. Whenever you connect to the Internet, special software informs your messaging server that you are online. In response, the server will notify you if any of your contacts are online. At the same time, it notifies your friends that you are online. You can then send messages directly back and forth to one another.

72. (p. 39) Describe a wiki and explain how a wiki differs from a blog. A wiki is a Web site designed to allow visitors to use their browser to add, edit, or delete that site's content. Wikis support collaborative writing in which there isn't a single expert author, but rather a community of interested people that builds knowledge over time. Although blogs may have multiple authors, community feedback is limited to adding comments to the site. Blogs are not a collaborative effort like wikis.

73. (p. 43) Explain how a search engine works. To use a search Web site, you enter a keyword or phrase reflecting the information you want. The search engine compares your entry against its database and returns a list of hits, or sites that contain the keywords. Each hit includes a link to the referenced Web page (or other resource) along with a brief discussion of the information contained at that location. Many searches result in a large number of hits. For example, if you were to enter the keyword music, you would get billions of hits. Search engines order the hits according to those sites that most likely contain the information requested and present the list to you in that order, usually in groups of 10.

74. (p. 44) Discuss the four elements to consider when evaluating the content and accuracy of information on the Web. There are four elements to consider when evaluating the accuracy of information on the Web: authority, accuracy, objectivity, and currency. Authority refers to the author's expertise on the subject. Is the site an official site for the information presented, or is the site an individual's personal Web site? In order to determine the accuracy of a Web site, consider whether or not the information has been critically reviewed for correctness prior to posting on the Web. Does the Web site provide a method to report inaccurate information to the authors? Objectivity is reached when the information is factually reported without an author bias. Finally, currency is the timeliness of the Web site. Is the information up to date? Does the site specify the date when the site was last updated?

75. (p. 44-45) Describe both the advantages, and the disadvantages associated with electronic commerce. Electronic commerce, also known as e-commerce, is the buying and selling of goods over the Internet. The underlying reason for the rapid growth in e-commerce is that it provides incentives for both buyers and sellers. From the buyer's perspective, goods and services can be purchased at any time of day or night. Traditional commerce is typically limited to standard business hours when the seller is open. Additionally, buyers no longer have to physically travel to the seller's location. From the seller's perspective, the costs associated with owning and operating a retail outlet can be eliminated. Another advantage is reduced inventory. Some of the disadvantages include the inability to provide immediate delivery of goods, the inability to "try on" prospective purchases, and questions relating to the security of online payments.

76. (p. 45) Describe the two greatest challenges for e-commerce. The two greatest challenges for e-commerce is the development of (1) fast, secure, and reliable payment methods for purchased goods and (2) providing convenient ways to provide required information such as mailing addresses and credit card information. The two basic payment options are: credit cards and digital cash. Credit cards are convenient and fast but credit card fraud is a major concern for both buyers and sellers. Digital cash is the Internet's equivalent to traditional cash. Buyers purchase digital cash from a third party (a bank that specializes in electronic currency) and use it to purchase goods. Sellers convert the digital cash to traditional currency through the third party. Although not as convenient as credit card purchases, digital cash is more secure.
