Excerpts

Excerpts

Communication Technologies presents a thorough introduction to the fast-paced world of end-user communication technology and telecommunications. End users are those persons within organizations who represent the final or ultimate users of computer systems and use hardware and software after it has been fully developed and marketed. Ends users are unlike computer programmers and engineers, who utilize their high levels of technical expertise to develop and test computer systems. Communication technology is the area of end-user computing that affects everyone. No one can work in today's highly technical office environment without knowledge of the fundamentals of electronic mail, voice processing, teleconferencing, wireless communication, networking, and related technologies. INTENDED AUDIENCE Communication Technologies is intended for use as a college textbook for end-user communication technologies and telecommunications application courses usually found in the office information systems and computer information systems disciplines. Specific applicable courses might include those with such titles as Communication Technologies, Telecommunications, Communication Hardware, or Information Systems Hardware. ORGANIZATION OF THE BOOK The book consists of 15 chapters arranged as follows: Part One, Communication Technology: Introduction, History, and Future; Part Two, Communication Technology Applications; Part Three, The Internet and Intranets; and Part Four, Networking Fundamentals. Each chapter begins with a brief description of the chapter and a What You Will Learn section, which provides specifics of the chapter content. Each chapter ends with Questions, Projects and Problems, and Vocabulary. A glossary, which includes all the terms in the Vocabulary sections, is provided at the end of the book. Chapters are organized as follows: Chapter 1: Introduction to Communication Technology. An introduction to the concept of communication technology is presented and related terminology is defined. Chapter 2: History and Future of Communication Technology. A discussion of the major historical events in communication technologies is provided, which serves as a foundation for understanding the present state of communication technologies. Chapter 3: Electronic Mail. An introduction to electronic mail (e-mail) is presented as a major communication technology application. Chapter 4: Teleconferencing. A discussion of the evolution of teleconferencing; teleconferencing applications; types of teleconferencing systems; benefits and drawbacks of teleconferencing; and how to plan, conduct, and evaluate a teleconference is provided. Chapter 5: Voice Processing and Facsimile. The functions, applications, benefits, and drawbacks of voice-processing and facsimile technologies are presented. Chapter 6: Wireless Communications. Wireless communications as it pertains to pagers, cellular phones, global location/navigation systems, and hand-held computers is discussed. Chapter 7: Telecommuting and Electronic Data Interchange. An introduction to telecommuting and electronic data interchange (EDI) as additional communication technology applications is provided. Chapter 8: Introduction to the Internet and Intranets. Various aspects relating to the Internet, including its history and uses, Internet addressing, connections, and protocols are covered. In addition, an explanation of intranets and how they are used, and what the future holds for the Internet and intranets are part of this chapter. Chapter 9: Electronic Mail Discussion Groups and Newsgroups. The use of electronic mail discussion groups and newsgroups is covered. Specifically, the chapter deals with finding, subscribing, unsubscribing, and communicating when using e-mail discussion groups, as well as how to use newsgroups. Chapter 10: World Wide Web. A description of the World Wide Web and a discussion of how information is accessed is provided. Also described are the features and types of Web browsers, how they are used, and how information is found. Chapter 11: Creating Web Pages. An examination of how Web browsers use hypertext markup language (HTML) to process information is provided. The basic HTML tags are presented, as well as instructions for using the FrontPage Express editor to create Web pages. Chapter 12: Additional Internet Utilities. The following Internet utilities are presented in this chapter: telnet, gopher, Archie and FTP search engines, and file transfer protocol. A definition is provided for each tool, as well as an explanation of how each tool is used. Chapter 13: Introduction to Networks. An introduction to networks and coverage of the following topics are included: types of networks, transmissions, and network media. Chapter 14: Telecommunication Models and Network Connectivity. Telecommunication models are discussed, as well as network topology, protocols, and methods for connecting networks. Chapter 15: Telephony. Voice communication technology, including a discussion of telephone circuits and the ways that computer and telephone technologies are being integrated, is presented. OEIS CURRICULUM MODEL The Organizational Systems Research Association (OSRA), formerly the Office Systems Research Association, "is a professional organization chartered for the purpose of pursuing research and education in the area of information technology and end-user information systems." OSRA provides a platform for dedicated professionals to meet and exchange ideas in the pursuit of excellence. In 1996, a dedicated team of information systems academics and practitioners worked together to address the need for collegiate preparation of people who have skills related to the following: information systems developer, troubleshooter, change agent, trainer, systems evaluator, or savvy business person. This group developed a four-year model curriculum entitled Organizational and End-User Information Systems (OEIS). The OEIS model curriculum underscores the notion that information systems at the desktop level are crucial to support organizational goals as well as to bolster and sustain employees' needs to do their jobs well and grow in their careers. It is intended to bring the impact of high-level talk about business reengineering to the practical level of implementation at the desktop, where it counts most. Increasingly, the end user, the person who actually uses systems in daily work activities, plays a variety of roles in systems needs assessment, design, implementation, and evaluation. The curriculum model is designed to challenge students to understand their information systems role from an organizational viewpoint, the perspectives and needs of the people they support, and technologies used or accessed at the desktop. The curriculum is the result of group collaboration and its innovativeness has been acknowledged by the academic community, students, and the business communities. Following are the 11 courses in the OEIS model. OEIS-1 Organizational and End-User Information Systems Concepts OEIS-2 End-User Technology Solutions OEIS-3 Organizational and End-User Information Systems Planning and Design OEIS-4 Organizational and End-User Information Systems Implementation and Evaluation OEIS-5 Designing and Managing Organizational Training OEIS-6 Communications Technologies OEIS-7 Cases in Organizational and End-User Information Systems OEIS-8 Information and Media Management OEIS-9 Special Topics OEIS-10 Business Process Redesign OEIS-11 Internship in Organizational and End-User Information Systems Course OEIS-6 provides a technical overview of electronic communication systems, including a strong foundation in local area network (LAN) management, Internet resources, and telecommunications and video technologies. Upon completion of this course, students should be able to: Demonstrate an understanding of the vocabulary of telecommunications Select telecommunication solutions to address identified problems Demonstrate effective LAN management Demonstrate effective use of online telecommunication services Determine effective use of a wide range of telecommunication technologies Discus effective application of emerging communication technologies This book is designed to serve the specific needs of course OEIS-6 in the OEIS curriculum. SUPPLEMENTARY AIDS An instructor's CD-ROM contains lesson plans, solutions, and PowerPoint slides for each chapter. A test bank is also provided.
