Conclusion: The Next Stages of Computing.Glossary.
The story of computing's development is as fascinating as anything in history. In just more than 50 years, we have gone from some sketchy ideas and concepts to a world in which the number of computing devices is reckoned in the hundreds of millions and growing fast.
Counting computer generations is necessarily controversialmachines don't have the same pedigrees as people. But, the five generations that are described here comprise close to a consensus. We'll characterize them briefly, then discuss the fundamental changes in economics that have resulted.
As I described this book project to friends and colleagues, a typical reaction was something like, "It can't be done. Things change too fast to be captured in a book. It will be out of date before it's printed." The part about things changing fast is certainly true. In the three to four months since the last edits were completed on the manuscript and until the first printed copies appear, some of the technologies mentioned will be on their way to obsolescence, and other new and exciting ones will appear. But, if the world of computing was really changing too fast to understand, the knowledge base of the people who provide the engines of innovation would be too small to sustain the rate of change. In fact, the number of people who really understand the full sweep of issues in computing and telecommunications is very small. If you read this book you will have a breadth of knowledge that is very rare.
And, whatever the critics say, it is possible to catch the train of technology and climb aboard. If you view this book as a reference to all that is new and current, you will be disappointed. For that, you need the Web, newspapers, and magazines. The real question is how do you get the foundation of knowledge that allows you to understand what the media are saying about technologynot just comprehend it, but put it in the perspective needed for employment, education, or investing? The situation for the average person with technology today would be analogous to that of an untrained person suddenly placed in a football game as a coach (the first and last sports analogy in the book, I promise). This coach doesn't know the rules, much less have any sense of how to develop a strategy, and things are changing so fast that he can't infer them from watching the game. To maintain the analogy then, the purpose of this book is to put you in the stands, and give you a rule book and a TV for instant replay (if I could choose, I would like the comparison to be with John Madden's analysis). This experience should give you the knowledge and perspective you need to be a coach, a referee, or even a player.
There are a variety of paths you can pursue when you complete the EGC. If you only want to continue to be far more informed than all but a handful of people, you simply need to use the Web, the newspapers, and magazines to keep current. To make this easier, we've provided a Web site,
www.prenhall.com/walters, that both provides direct information and offers links to some of the best sources for breaking knowledge (the Web site also includes answers to the questions provided at the end of each chapter). Alternatively, if you want to go deeper, this book is a foundation for more focused study. To learn in depth, you really (still) need books, and the Suggestions for Further Reading includes an array of choices. The EGC Web site updates these on a regular basis. Needless to say, there are a variety of other directions you could choose. Whatever your decision, I hope this volume launches you in a productive and pleasant direction.
