Computer networks allow multiple computers and devices to communicate with each other and share information and resources. This allows companies to communicate more effectively, improve productivity and provide better service to clients. A computer network is composed of two fundamental components: nodes or devices, and links. Nodes are devices that communicate, like mobile devices, computers and printers, and links are physical connections that transfer data between them. These links are made up of cables, fiber optics and wireless signals such as Wi-Fi. Data is transferred from one node (or device) to another by using a set pre-programmed communication protocols.
