INTRODUCTION
You already know from reading this book that virtually every electronic product has a digital computer built into it in the form of an embedded controller or microcomputer. But one other fact about electronic equipment that you may not know is that a large percentage of these devices are now being interconnected to one another to form networks. This is particularly true of computers. After all, what computer today is not connected to some form of network? And while we may be nearing the point where all computers are networked, the trend con- tinues toward networking many other non-computer devices. This chapter takes a look at networking concepts and the most popular forms of networks being used today, both wired and wireless.
