Abstract

This chapter and the following one deal with applications of the material developed in the preceding chapters. Needless to say, there are numerous other examples for which analog and digital electronics have served as the underlying base. But perhaps for society today, the most pronounced developments in technology have been the digital computer and more recently digital communication networks. Because these two disciplines share the same binary language of 0’s and 1’s, computing and communications have merged and advanced with revolutionary results as exemplified by the Internet and its World Wide Web. The information revolution, also known as the “third” revolution, which the digital computer heralded 50 years ago has profoundly changed the way society in general works and interacts. This revolution followed the 18th century industrial revolution, which in turn followed the agricultural revolution of about 10,000 years ago. All have been technology-based, but the “third” revolution is by far the most sophisticated. This chapter will try to provide you with a working knowledge of the computer–specifically the personal computer.
