For example, a user could program the VCR in the living room from his TV in the bedroom, again, regardless of which manufacturer made either device. In a data network, a repeater can relay messages between subnetworks that use different protocols or cable types. Hubs can operate as repeaters by relaying messages to all connected computers. A repeater however does not have the capability to do the intelligent routing performed by bridges and routers, and simply extends cabling distances by regenerating signals to continue its propagation, usually increasing total distance or coverage area. A repeater is a network device that repeats a signal from one port onto the other ports to which it is connected .
Repeaters are low-level devices that amplify or regenerate weak signals.
A repeater merely passes along bits of data, even if a data frame is corrupt. The gateway is dedicated to the task of a router and generally performs protocol conversion between the Internet backbone and the home network, data translation or conversion, and message handling. A display with a finer grid contains more pixels and thus has a higher resolution, capable of reproducing more detail in an image. The Resource Manager allows for the possibility of sharing devices. The sharing function is determined by the devices themselves.
