Computer networks allow multiple computers and devices to communicate with each other and share information and resources. This allows companies to communicate more effectively and enhance productivity. They also offer better customer service. A computer network is comprised of two basic elements: devices or nodes, and links. Nodes are communication endpoints, such as printers, computers and mobile devices, while links are the physical connections that transfer information between them. These links include fiber optics, cables and wireless signals such as Wi-Fi. Data is transferred from one node to the next by using a set of pre-programmed rules called communication protocols.
