A computer network consists of a collection of computers, printers and other devices that are connected together so that they can talk to each other. Local Area Networks (LANs), Wide Area Networks (WANs) and Virtual Private Networks (VPNs) are all examples of computer networks. Local Area Networks (LANs) LANs connect computers and other devices that are located physically close to each other. A computer network in a house or office is an example of a LAN.
