章节摘录

插图:The purpose of this book is to help you become competent in computer-related skills. Computer competency: This notion may not be familiar to you, but it's easy to understand. Specifically, we want to help you walk into a job and immediately be valuable to an employer.In this chapter, we first present an overview of an information system: people, procedures, software, hardware, and data. Competent end users need to understand these basic parts and how connectivity through the Internet and the Web expands the role of information technology (IT) in our lives. In subsequent chapters, we will describe these parts of an information system in detail.Fifteen years ago, most people had little to do with computers, at least directly. Of course, they filled out computerized forms, took computerized tests, and paid computerized bills. But the real work with computers was handled by specialists-programmers, data entry clerks, and computer operators.Then microcomputers came along and changed everything. Today it is easy for nearly everybody to use a computer. Now:Microcomputers are common tools in all areas of life. Writers write, artists draw, engineers and scientists calculate-all on microcomputers. Students and businesspeople do all this, and more.New forms of learning have developed. People who are homebound, who work odd hours, or who travel frequently may take courses on the Web. A college course need not fit within the usual time of a quarter or a semester.New ways to communicate, to find people with similar interests, and to buy goods are available. All kinds of people are using electronic mail, electronic commerce, and the Internet to meet and to share ideas and products.What about you? How are you using information technology? Many interesting and practical uses have recently surfaced to make our personal lives richer and more entertaining. These applications range from recording digital video clips to creating personalized Web sites.Competent end users need to know the five parts of an information system: people, procedures, soft-ware, hardware, and data. Additionally, they need to understand connectivity, the wireless revolution, the Internet, and the Web and to recognize the role of in-formation technology in their professional and personal lives.
