As networking hardware becomes more affordable, local area networks (LANs) are being used widely in offices and homes. They can serve two or more computers and are a cost-saving approach since expensive devices like high-quality printers or storage drives are shared rather than purchased separately for each computer. Internet access for all can be achieved through a single point, a definite advantage in terms of cost control and security. Even more importantly, networks save time by giving you and others the convenience of sharing information quickly and easily. The adaptability of a LAN makes it easy to customize your network to fit the needs of your business or household now and over time.
