Electronic Mail Protocols 1. Introduce the term electronic mail e-mail. Introduce the terms e-mail server and e-mail client software. Emphasize that if e-mail messages did not follow standard rules, an e-mail message created by a person using one e-mail client program could not be read by a person using a different e-mail client program. Web Page Request and Delivery Protocols 1. Quick Quiz 3 1. Answer: protocol 2. True or False The IP controls the disassembly of a message or a file into packets before it is transmitted over the Internet, and it controls the reassembly of those packets into their original formats when they reach their destinations.
Answer: False 3. Answer: subnetting 4. Answer: Web server. Emergence of the World Wide Web 1. Set the stage by mentioning that the ideas behind the Web developed from innovative ways of thinking about and organizing information storage and retrieval. Point out that two important ideas that became key technological elements of the Web are hypertext and graphical user interfaces. The Development of Hypertext 1. Briefly describe: a. Graphical Interfaces for Hypertext 1. Introduce the term Web browser.
Describe the difference between an HTML document and a word-processing document. Define the basic functions of a graphical user interface GUI : presenting program control functions and program output to users and accepting their input.
The World Wide Web 1. Note that initially, few people outside the scientific research community had software that could read HTML documents on the World Wide Web. Use Figure to illustrate the overall rapid growth rate of the Web. Invite students to offer ideas explaining the increase in the number of Web sites that occurred from to , with the number of sites doubling.
The Deep Web 1. Using the example of visiting Amazon. Note that the deep Web can be difficult or impossible to search because its information is not stored on the Web, but in databases that are searched only when a user requests that information through the Web site that maintains the database. Domain Names 1. Introduce the concept of domain names and the term top-level domain TLD. Quick Quiz 4 1. Answer: Web browser 2. Answer: deep Web 4. Answer: Domain names. Markup Languages and the Web 1.
Discuss the most important parts of a Web page - the structure of the page and the text that makes up the main part of the page. Hypertext Markup Language 1. Introduce the concept of hypertext elements. The latest version of HTML is 5. HTML Tags 1. Most HTML tags have an opening tag and a closing tag that format the text between them.
Figure shows some sample text marked up with HTML tags. Figure shows this text as it appears in a Web browser. HTML Links 1. Note that users can read Web pages in serial order or in whatever order they prefer by following hyperlinks.
Figure illustrates the differences between reading a paper catalog in a linear way and reading a hypertext catalog in a nonlinear way. Introduce the terms linear hyperlink structure, hierarchical hyperlink structure, home page or start page, and site map. Figure illustrates three common Web page organization structures: linear, hierarchical and hybrid.
Introduce the term anchor tag. Cascading Style Sheets 1. Introduce the terms style sheet and cascading style sheet. Note that the term cascading is used because designers can apply many style sheets to the same Web page, one on top of the other, and the styles from each style sheet flow or cascade into the next. As companies began to conduct business online, they turned to XML to help them maintain Web pages that contained large amounts of data.
Use Figures and to illustrate how HTML might be used to display a Web page that includes a list of countries and some basic facts about each country. First, XML is not a markup language with defined tags. It is a framework within which individuals, companies, and other organizations can create their own sets of tags. Second, XML tags do not specify how text appears on a Web page; the tags convey the meaning the semantics of the information included within them. Emphasize that the greatest strengths of XML is that allows users to define their own tags, but that this is also its greatest weakness.
To overcome that weakness, many companies have agreed to follow common standards for XML tags. Introduce the term XML vocabulary.
Use Figure to illustrate a diagram showing one way that a Web server might process HTTP requests for Web pages generated from an XML database in different formats for different Web browsing devices. Quick Quiz 5 1. Answer: text markup 2. Answer: linear hyperlink 3. Answer: anchor tag 4. Answer: True. Internet Connection Options 1. Introduce the term Internet access providers IAPs. Connectivity Overview 1. Review the most common connection types ISPs offer: voice-grade telephone lines, various types of broadband connections, leased lines, and wireless.
Introduce the term bandwidth. Discuss the major distinguishing factors between various ISPs and their connection options - that is, the bandwidth they offer. Introduce the term net bandwidth. Connection types include symmetric connections and asymmetric connections. Introduce the terms upstream bandwidth upload bandwidth and downstream bandwidth downstream bandwidth or downlink bandwidth. Voice-Grade Telephone Connections 1. Introduce the terms plain old telephone service POTS and broadband services.
Broadband Services 1. Explain that DSL connection methods do not use a modem. Note that unlike DSL, cable modem connection bandwidths vary with the number of other subscribers competing for the shared resource. Leased-Line Connections 1. Introduce the terms T1 line, T3 line, frame relay, asynchronous transfer mode ATM , and optical fiber. Note that the Internet was built on telephone company wires and infrastructure but that many Internet users today use some form of wireless connection.
Wireless Ethernet Wi-Fi 1. Introduce the terms Wi-Fi and wireless Ethernet. Note that the technology is also known by its network specification number Introduce the terms wireless access point WAP , roaming, and hot spots.
Personal area networks 1. One major advantage of Bluetooth technology is that it consumes very little power, which is an important consideration for mobile devices. Many observers believe that UWB technologies will be used in future personal area networking applications such as home media centers and in linking mobile phones to the Internet.
An increasing number of applications have been developed to run on ZigBee that control home energy management systems including lighting, heating, cooling , commercial building automation, security systems, and remote controls for consumer electronic products. Fixed-Point Wireless 1. Introduce the terms fixed-point wireless, repeaters transceivers and mesh routing.
Satellite Microwave 1. Satellite microwave transmissions made Internet connection possible for the first time to many people in rural areas and are now used by airlines to provide inflight Internet. While satellite networks were the only option for many years, many types of wireless networks are now available. Mobile Telephone Networks 1. Introduce the term short message service SMS. Note that most tablet devices, mobile phones, and smartphones have the ability to use either a mobile telephone network or a locally available wireless network.
Refer to Figure to summarize the speed and cost information for the most commonly available wired and wireless options for connecting a home or business to the Internet. Quick Quiz 6 1. Answer: Bandwidth. Answer: voice-grade 4. Answer: Wi-Fi, wireless Ethernet, or Answer: short message service SMS.
Internet2 and the Semantic Web 1. Students will find it interesting to learn that Internet2 is also used by universities to conduct large collaborative research projects that require several supercomputers connected at very fast speeds or that use multiple video feeds, features that would be impossible on the Internet given its lower bandwidth limits. Introduce the terms Semantic Web, software agents, resource description framework RDF , and ontology. Note that thus far, several areas of scientific inquiry have begun developing ontologies that will become the building blocks of the Semantic Web in their areas.
Other sciences, such as climatology, hydrology, and oceanography have similar incentives as many researchers around the world work on common problems such as global warming and scientists are developing ontologies for their disciplines.
Introduce students to the Dbpedia project. Note that current commercial applications of Semantic Web community research include the natural language interfaces of mobile phone search utilities such as Siri and Google Now. Quick Quiz 7 1. Answer: Internet2 2. Answer: resource description framework RDF 3.
