Local area networks cover a single site, such as an office building. They facilitate sharing of resources, such as printers and storage media. Local area networks are normally created by wired connections, but they can have wireless connections. They are characterized by high-speed communication and are cheaper to implement than other computer networks. Metropolitan area networks cover a small region, an entire campus or a whole city. They connect many local area networks. Wide area networks cover a whole country and can span across the entire world, such as the Internet.
