Acomputer network, ordata network, is adigitaltelecommunications networkwhich allowsnodesto share resources. In computer networks,computing devicesexchange datawith each other using connections between nodes (data links.) These data links are established overcable mediasuch as wires or optic cables, orwireless mediasuch asWiFi.Network computer devices that originate,routeand terminate thedata are called network nodes.[1]Nodes can includehostssuch aspersonal computers,phones,serversas well asnetworking hardware. Two such devices canbe said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols arelayered(i.e. carried aspayload) over other more general communications protocols. This formidable collection ofinformation technologyrequires skillednetwork managementto keep it allrunning reliably.Computer networks support an enormous number ofapplicationsandservicessuch as access to theWorld Wide Web,digital video,digital audio, shared use ofapplication and storage servers, printers, andfax machines, and use ofemailandinstant messagingapplications as well as many others. Computer networks differ in thetransmission mediumused to carry their signals,communications protocolsto organize network traffic, the network's size,topology,traffic controlmechanism and organizational intent. The best-known computer network is the Internet.
