A household data network connects two or more computers, printers, or other devices, using cables or radio links.
A computer connected to the network can exchange with other devices on the same network any information that can be converted to digital data.This can include computer files and commands, text and voice messages, music, and video. The same network can connect Internet access points, video cameras, and printers. In other words, a home computer network can distribute information to and from every room in the house.
Most home networks handle two kinds of data: information that originates outside the local network, including Web pages and e-mail that come in through the Internet; and data that move from one local device to another, such as files, remote-control commands, and signals from remote cameras and other sensors. The same home network can handle both internal and external data.
