From the small local corner store to the largest hospital, computers are in every gas station, grocery store, bank, restaurant, beauty shop, and doctor's office around. From a consumer's point of view - you may not think that's much to worry about. But along with computers, we've also been infiltrated with a little thing called "self-service. Create a barrier between your computer and prying eyes. Anti-virus/anti-spyware programs are only effective after the effect.

These requirements don't make computers any less easier to operate, but they don't make them that much harder either. Within Windows, you can set up a home network similar to the way that you set up an Internet connection. Only this time, you'll set up a LAN (Local Area Network) connection. Windows should walk you through setting up a LAN after starting the computer and once complete, you can begin to connect one of your machines to the network.
