Telecommunication networks
A communications network is a collection of transmitters receivers and communications channels,,, That send messages to one another. Some digital communications networks contain one or more routers that work together to. Transmit information to the correct user.An analog communications network consists of one or more switches that establish a connection between two or more, users. For both types, of network repeaters may be necessary to amplify or recreate the signal when it is being transmitted over. Long distances. This is to combat attenuation that can render the signal indistinguishable from the noise.Another advantage of digital systems over analog is that their output is easier to store, in memory i.e. Two voltage states. (high and low) are easier to store than a continuous range of states.
