CHAPTER 1: CHAPTER 1: INFORMATION TECHNOLOGY, THE INTERNET, AND YOU
The purpose of this book is to help you become competent with computer technology. Computer competency refers to acquiring computer-related skills—indispensable tools for today. They include how to effectively use popular application packages and the Internet.
In this chapter, I present an overview of an information system: people, procedures, software, hardware, and data. It is essential to understand these basic parts and how connectivity through the Internet and the Web expands the role of information technology in our lives. Later, 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 was handled by specialists. Then microcomputers came along and changed everything. Today it is easy for nearly everybody to use a computer.
To be competent with computer technology, you need to know the five parts of an information system: people, procedures, software, hardware, and data. You also need to understand connectivity, the wireless revolution, the Internet, and the Web and to recognize the role of information technology in your personal and professional life.
And from my own experince i got lots useful about technology and its uses. I knew these things before, but this book made my imagination more broader.

- 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 Web courses. A college course need not fit within a quarter or a semester.
- New ways to communicate, to find people with similar interests, and to buy goods are available. People use electronic mail, electronic commerce, and the Internet to meet and to share ideas and products.
