Frequently asked questions What is a network? A network is a collection of devices such as computers, printers, Ethernet hubs, wireless access points, and routers connected together for communication through cables or through a wireless connection. A network can be wired, wireless, or designed to have both wired and wireless devices. Devices on a wired network use cables to communicate with each other. Devices on a wireless network use radio waves instead of cables to communicate with each other. For a device to be able to communicate wirelessly, it must have a wireless print server attached or installed that lets it receive and transmit radio waves. How are home networks configured? For desktop computers, laptops, and printers to communicate with each other over a network, they must be connected by cables and/or have wireless network adapters built in or installed in them. There are different ways a network can be set up. Five common examples appear below. Note: The printers in the following diagrams represent printers with internal print servers built in to them so that they can communicate over a network.
