Book excerpt: Bill Gates' famously bold prediction -- that one day, every home would have a computer -- is now, if anything, a huge understatement, with many households (and certainly most buisinesses, however small) boasting multiple machines. Written by a working PC technician, this book takes you through the basics - the jobs you can do yourself with a bit of know how and a screwdriver. It tells you what you need to know about hardware and how to get the most from your operating system tools (including Windows 7). If you have more than one PC you will learn how to network them to share your printer / scanner / Internet connection, using conventional cables or wireless technology. And for the jobs that you can't do yourself, there are some guidelines on how to find and brief a PC technician and how to check that you're getting the work you pay for. Ideal for small enterprises - businesses, voluntary organisations etc who need to implement small networks, share resources etc this book is the perfect guide to installing and maintaining networks, disaster recovery, installing applications, client/server systems and security - all of the skills a small enterprise needs with minimal outside help.
