A computer network is composed of multiple connected Computers that communicate over a wired or wireless medium to share data and other resources. For instance, a home computer network may consist of two or more computers that share files and a printer using the network. The size and scalability of any computer network are determined both by the physical medium of communication and by the software controlling the communication (i.e., the Protocols ). RJ-45 ( 8P8C ) Patch Cord of the type commonly used to connect network devices.]] DEFINITION Experts in the field of networking debate whether ''two'' computers that are connected together using some form of communications medium constitute a network. Therefore, some works state that a network requires ''three'' connected computers. One such source, "Telecommunications: Glossary of Telecommunication Terms" states that a computer network is "A network of data processing nodes that are interconnected for the purpose of data communication". The term "network" being defined in the same document as "An interconnection of three or more communicating entities". A computer connected to a non-computing device (e.g., networked to a printer via an Ethernet link) may also represent a computer network, although this article does not address this configuration. This article uses the definition which requires ''two'' or more computers to be connected together to form a network. |
