It doesn't take much to disrupt any unstable equilibrium, and the result is always disaster. Even the most seemingly innocuous change to your computing environment can precipitate a computer disaster that results in the loss of irreplaceable data, and in many cases, the loss of use of your computer. These disasters come in many guises. They can be caused by computer viruses, hackers, or mechanical failure. They can be self-inflicted or inflicted by cruel fate. There are disasters of mysterious, unknown origin: One day, your computer is working just fine, and the next day when you turn it on you find that you are the proud owner of the world's largest and most expensive paperweight. When disaster strikes, Murphy's Law dictates that it will happen at the worst possible time - when you are trying to meet a critical deadline. Many computer disasters are preventable, through the use of certain tools and procedures. Some disasters are unpredictable and unavoidable, such as a hard disk crash or when the installation of a new software application trashes your computer. |

Personal computers play a more important role in our lives than ever before. We use our computers to store digital photographs, music, videos, web pages, financial records and other critical documents. We depend on our computers to be available night and day so that we can do e-mail, e-commerce, e-banking, web surfing, homework, investing, and a hundred other tasks – things that were once considered to be conveniences of life and are now considered to be essential. Every time we learn how to use a new application, we create more data and expose ourselves to greater risk of losing irreplaceable data. Yet most people never consider the possibility of a computer disaster or the gut wrenching impact that such a disaster will have on their lives until it is too late. As we find more ways to use our computers, our computing environments become increasingly complex and more prone to failure. Our computers are unstable equilibriums, where the slightest change can precipitate a colossal computer disaster. |
