A '''node''' is any point in a [[network]].It must be capable of sending or receiving information, or forwarding it to another node (and in some cases, doing all three). End-user devices such as personal computers are nodes, as are the devices which connect those pieces of equipment, including [[Router (computing)|router]]s, modems, and switches.<ref>https://www.lifewire.com/what-is-a-node-4155598</ref>
