Computer can communicate with another computer down the street, across town, across the country and across the world, thanks to a vast array of networks. The World Wide Web is a system of interconnected information sources, however, it would be meaningless without networks that allow computers to access information and communicate with each other. A local area network, or LAN, is a connection of computers within a small area, such as an office, a building or multiple buildings located close together. Local area networks can be as broad as connecting computers within a college campus, or as simple as linking two computers in a household. A LAN is relatively inexpensive compared to other types of network applications, and can be built with wired or wireless connections.
