Wireless networking is undergoing a transformation from What has been primarily a medium for supporting voice traffic between telephones, into What is increasingly becoming a medium for supporting traffic among a variety of digital devices transmitting media of many types (voice, data, images, video. etc.) Wireline networking underwent a similar transformation in the 1990s, which led to an enormous build-up in the capacity of such networks, primarily through the addition of new optical fiber, switches and other infrastructure.

The field of cyber security, or information security, or information assurance, depending on your preference, is an interdisciplinary one. It is part computer science, part statistics, part psychology, part law, and a part of many other fields. Moreover, any cyber security practi- tioner needs to know What he or she is protecting and where to pri- oritize. Just as someone should not spend $100 to protect something worth $10, one cannot be blind to the other disciplines.

With all the recent hype over radio frequency identification (RFID) and the requirements to implement it, you might think that RFID can turn water into wine, transform lead into gold, and cure the world’s diseases. You might also be worried that RFID will enable Big Brother to track your move- ments to within a foot of your location from a satellite five hundred miles up in space. The truth is, RFID can do none of these things. In this chapter, you find out the basics of What RFID is, What forces are dri- ving RFID as a replacement for the bar code in the marketplace, and What benefits RFID can offer

To a quantum mechanic the whole universe is one godawful big interacting wavefunction ? but to the rest of us, it’s a world full of separate and distinguishable objects that hurt us when we kick them. At a few months of age, human children recognize objects, expect them to be permanent and move continuously, and display surprise when they aren’t or don’t. We associate visual, tactile, and in some cases audible and olfactory sensations with identifiable physical things. We’re hardwired to understand our environment as being composed of separable things with specific properties and locations. We understand the world in terms of What was where when.

Fun. We (your authors) wanted a word to describe our ultimate goal for this book, as well as a word we hope you (our reader) will use to describe it, and that’s the one we chose. There are others goals, of course, but in the end, when you’ve finished the book, we’re hoping you’ll have enjoyed the activities described in these pages. Many books use the Introduction to explain exactly What the book is about, What the reader will learn, What the reader needs (a skill or maybe an item or piece of software), and What the reader will be left with when that last page is completed. And this Introduction will do those things, but … hopefully it’ll make you excited to get started.

There’s a story (it’s either an old vaudeville joke or a Zen koan) in which a fisherman asks a fish, “What’s the water like down there?” and the fish replies “What is water?” If the story is just a joke, the point is to make us laugh; but if it’s a koan, the point is that the most obvious and ubiquitous parts of our immediate environ- ment are, paradoxically, often the easiest to overlook.

I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95! Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and think of all the possibilities built into that piece of hardware. I am amazed by What has happened to everything from toasters to car engines. Who-da-thunk-it 40 years ago?
