Devices on one network can communicate with devices on another network via a Utility server
The network may also include a node external to the subnetwork, e.g., a utility server. A system server of the customer periodically connects to a utility server of the utility company using a standard computer protocol, such as Hypertext Transfer Protocol (HTTP).
Unlike less advanced network hubs, a network switch forwards data only to one or multiple devices that need to receive it, rather than broadcasting the same data out of each of its ports. It works on OSI layer 2. Bridge: a device that connects multiple network segments. It works on OSI layers 1 and 2.
Utility computing, or The Computer Utility, is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate.
