Tie home computers into
wireless or wired networks Once upon a time, when Bill Gates was only very, very rich, relatively few homes had computers and VERY few had more than one computer. But things have changed. With the price of machines dropping every day, multi-computer households are common. People replace machines every few years. The kids (or maybe the parents) get the old ones. That raises the problem of accessing printers and the Internet. Fortunately, there's some excellent networking equipment around. Basically, you can do it four ways: via cables, through the telephone or electrical lines, or through the air. None of this is very expensive. Once you're networked, everybody can use one printer or share a single Internet access point. This works especially well with a broadband Internet connection. Everyone can use it simultaneously. The fastest connections are done with Ethernet, which is also the oldest system. Newer systems can be run through the phone lines, assuming you have a jack near every computer, or your home's electrical lines. Many people today are using wireless, or Wi-Fi, as the cool people say. This is relatively easy to set up. But follow security instructions carefully. If you don't, someone nearby could pluck your data from the air. If you're an absolute beginner, ask a knowledgeable person to help you set up your network. But if you're comfortable with computers, you should be able to handle the job. Sharing of files and printers is great. But when you are using dial-up to get on the Internet, or if you only have one computer in the house using an always-on Internet connection like cable or DSL, sharing is unnecessary and it can be dangerous, because an intruder might be able to access it. That's why you want to disable file and printer sharing if you're not using it. Here's how to disable it in Windows XP or Vista:
Remember, install a firewall. And don't forget to use passwords to protect yourself from intruders. Some of these people use dictionary programs to break passwords, so never use a real word and don't use names, either. Instead, use an alphanumeric combination, such as A5i9lj2t. And it doesn't hurt to throw in some symbols, too. For example, use the asterisk, so it might look like A5i*9lj2t. And why not be really inventive and come up with something that has some meaning? These are also a good mnemonic device. But don't use any of these listed below; they're only suggestions:
