Introduction

Introduction

"Any sufficiently advanced technology is indistinguishable from magic."
Arthur C. Clarke

SORCERERS have their magic wands—powerful, potentially dangerous tools with lives of their own. Witches have their familiars—creatures disguised as household beasts that could, if they choose, wreak the witches' havoc. Mystics have their golems—beings built of wood and tin brought to life to do their masters' bidding.

We have our personal computers.

PCs, too, are powerful creations that often seem to have a life of their own. Usually, they respond to a wave of a mouse or a spoken incantation by performing tasks we couldn't imagine doing ourselves without some sort of preternatural help. But even as computers successfully carry out our commands, it's often difficult to quell the feeling that there's some wizardry at work here.

And then there are the times when our PCs, like malevolent spirits, rebel and open the gates of chaos onto our neatly ordered columns of numbers, our carefully wrought sentences, and our beautifully crafted graphics. When that happens, we're often convinced that we are, indeed, playing with power not entirely under our control. We become sorcerers' apprentices, whose every attempt to right things leads to deeper trouble.

Whether our personal computers are faithful servants or imps, most of us soon realize there's much more going on inside those silent boxes than we really understand. PCs are secretive. Open their tightly sealed cases and you're confronted with poker-faced components. Few give any clues as to what they're about. Most of them consist of sphinx-like microchips that offer no more information about themselves than some obscure code printed on their impenetrable surfaces. The maze of circuit tracings etched on the boards is fascinating, but meaningless, hieroglyphics. Some crucial parts, such as the hard drive and power supply, are sealed with printed omens about the dangers of peeking inside—omens that put to shame the warnings on a pharaoh's tomb.

This book is based on two ideas. One is that the magic we understand is safer and more powerful than the magic we don't. This is not a hands-on how-to book. Don't look for any instructions for taking a screwdriver to this part or the other. But perhaps your knowing more about what's going on inside all those stoic components makes them a little less formidable when something does go awry. The second idea behind this book is that knowledge, in itself, is a worthwhile and enjoyable goal. This book is written to respond to your random musings about the goings-on inside that box you sit in front of several hours a day. If this book puts your questions to rest—or raises new ones—it will have done its job.

At the same time, however, I'm trusting that knowing the secrets behind the magician's legerdemain won't spoil the show. This is a real danger. Mystery is often as compelling as knowledge. I'd hate to think that anything you read in this book takes away that sense of wonder you have when you manage to make your PC do some grand, new trick. I hope that, instead, this book makes you a more confident sorcerer.

Customer Reviews

I highly recommend this book to both children and adults who have an interest in learning about the workings of computers.
J. Macdonald
Rather than add to endless "This sucks!" "No it doesn't!" arguments, my review is simple - if you need an understanding of how computers work, give this book a try.
J. Slaybaugh
This book is well thought out, well organized, and presents difficult technical concepts in way that's easy to understand.

I have used this book for a introductory high school technology course, but it is getting very dated. Many refernces are to technology my students have never seen (because they are old) and leaves out many newer technologies. Any chance of an updated version anytime soon?

This is my third purchase of "How Computers Work." The first editions included an excellent CD that worked with Windows 3.11 and later with Windows95 and 98. The CD was excellent and an wonderful teaching tool. (I teach an A+ Computer Repair-type class at the high school level.)

My second purchase included a CD that was somewhat useful -- sort of a lame interactive presentation.

This edition no longer includes the CD, which is why I made this purchase. The lesson here is not to order something on-line late at night when one is not paying attention -- my fault.

On a positive note, I had our high school librarian order several copies for my students to check out.

The book has good, up-to-date info, great illustrations, but I miss the original CD.

This book was exactly for me when I got it. Before when I had this book, I had questions! I mean how do PCB makes so fantastic clear pictures on desktop and many many many more questions in my mine! If you can't stand using a device and not knowing what's going on inside, WELL THIS BOOK IS FOR YOU. Plus it explains about IP adresses, wireless access point, modems, subnet mask, NIC,ect. really well. Now I can't even stand putting it down. I'm telling you again, all your questions about modern day technology will be answered!

This book is for people who like to know what is going on, but not for applying this knowledge. You won't be able to upgrade; or troubleshoot your computer if you read it, and you won't be able fix your software either. The reason for the 4 stars is that the title is somewhat misleading. Otherwise, if you belong to the audience above, then it does a good job. On the other hand, if you want to do something specific, don't buy it, it won't move you in that direction, it is too shallow for practical purposes.

I've worked in computer support for 6 years, but since I haven't been to class on most topics, I have gaps in my knowledge. This book gives 2 pages for each topic, and is great for me, or for a curious person just wanting to learn more about computers. You can read just the topics you are interested in, in any order, or the entire book. Great charts, precise and helpful explanations, and lots of colorful diagrams. I rec it for all levels of computer users!

If you're looking for a book that will bring your computer literacy up to date this is it. A great book to bring seasoned users up to speed with current mobile technology and great for understanding how things work from component level to system level.

I purchased this book because it had such high ratings. However, the publisher (Kindle Version) did the authors no justice because they did not follow instructions for incorporating graphics in ebooks. All graphics in the Kindle edition are virtually useless.

Format: Paperback Verified Purchase
This book is a great value for anyone seeking a general understanding of how computers work. The author and illustrator effectively cover a tremendous breadth of material with simple text and excellent visual aids, but without being silly or so simplistic as to be meaningless. The material is broken up into logical chapters, but is served up in 2-page increments, so the book is easy to pick up for a few minutes, learn about a concept or method, and then go about other activities. It also flows in an incremental manner that builds from the basics of hardware and software all the way up to the internet and complicated graphics programs. It pays about equal attention to hardware and software, and introduces common but often misunderstood terms and principles. I would highly recommend the book to non-subject-matter-experts seeking an architectural or conceptual view of computers. While one will not be able to build a computer or write code after reading only this book, he or she will certainly have a much better idea of how all the hardware and software components of a computer and network work together to perform a myriad of functions. Topics are as diverse as transistor operation, boolean algebra, spreadsheets, digital photography, computer games, printers, Google, eBay, viruses, security, data storage, local area networks, power supplies, joysticks, operating systems, and many subjects in between. I have enjoyed and appreciated this book. My thanks to the author and illustrator--they've helped me a great deal!
