It presents a lot of terminology, and discusses the history of computers in the context of this terminology. Section A defines the characteristics of a computer system, and provides an overview of data, information, and files. It concludes with an introduction to application software, operating systems, and platform compatibility. Students acquire a basic vocabulary to discuss computer hardware and software. They learn how to distinguish one computer system from another, and to identify the typical equipment in a personal computer system. Students discover how computers are categorized and how they are used in business environment. They also explore files, including data and executable files, and learn the difference between application software and operating systems. Section B offers an overview of the Internet, including its structure and resources. Students learn their options for connecting to the Internet, how to choose an Internet service provider, and what they need to access the Internet. This section also discusses user IDs and passwords, and how to choose appropriate ones. Section C provides tools and techniques for working with the Web. It defines terminology, including Web sites, Web servers, URLs, HTTP, HTML, and browsers. Students examine Web pages in Internet Explorer, and learn how to use search engines to find information. Section D covers e-mail basics, and explains who can use e-mail, and how to perform email tasks, such as creating, sending, replying to, and forwarding e-mail messages. Students learn how to send files as attachments as well. Students learn to observe accepted e-mail etiquette, the types of e-mail services they can use, and the differences between POP and Web-based e-mail. The TechTalk section of the chapter is devoted to the boot process. Students learn the purpose of the boot process, the sequence of boot events, and how to interpret the information that appears on-screen during booting. The Chapter 1 Issue section discusses e-mail privacy, explaining who has access to e-mail messages and why. Computers in Context focuses on the role of computers in the implementation of the U.S. Government’s Homeland Security Act. The Labs for this chapter give students practice in operating a personal computer, making a dial-up connection, browsing and searching, and using e-mail. Because this chapter sets the foundation for working with a computer and the Internet, students should thoroughly understand the topics in each section before they complete the lab assignments. CHAPTER NOTES If you have a computer system in your classroom on a regular basis, you can use it as a visual aid when you discuss computer hardware configurations. You might want to request a computer and projection system for your classroom on a permanent basis. You can use this to project the images and animations in the Course Presenter. New Perspectives on Computer Concepts, 8th Edition Chapter 1-3 You might also want to project the Course Labs, many of which can be used for classroom demonstrations, as well as Student Lab activities at the end of the chapter. If your computer labs are scheduled to capacity, judicious use of the Course Labs as classroom demonstrations can reduce the amount of time your students will spend in the computer labs. If students can gain access to the network drive at the school lab files can be posted for students to work in the labs.
