A computer network is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as Wi-Fi. Computer networks support an enormous number of applications and services such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications as well as many others. Computer networks differ in the transmission medium used to carry their signals, communications protocols to organize network traffic, the network’s size, topology, traffic control mechanism and organizational intent. The best-known computer network is the Internet.
