Networking
Networks are used for two basic reasons: file sharing and internet connection sharing between computers. This can be done using wired and wireless networking, and most often can be done without having to purchase a new computer system.
Networks can be set up to cater to your needs with regards to security both within and outside the network, and gives you the flexibility of who can access the information contained on the network.
A networked internet connection can save you both time and money, as it is necessary to have only one internet account for your home or office, as well as taking advantage of the speed of a broadband connection throughout your network.
