A Network is a set of computers connected so that they can communicate and share information and also their hardware. A Local Area Network (LAN) that you typically find in an office is small, perhaps a few computers sharing an internet connection and a few printers. A Wide Area Network (WAN) is large, with many computers linked between towns or even countries. The Internet is considered a network of networks that circles the globe. Most major networks are linked to this global network called the Internet.
