“Networking technology is at the heart of the Internet connecting devices and local networks with the global public Internet. Planning, designing, building, managing, and supporting IP networks all require dedicated networking skills”

- Tae Yoo, Senior Vice President, Corporate Affairs at Cisco

A network is a set of devices (often denoted as nodes) joined by communication links. A node can be a computer, printer, or any other device able of sending and/or getting data produced by other nodes on the network. A link can be a cable, optical fiber, or any medium which can transfer a signal conveying information.
