Telecommunication is the long-range transmission of information by electromagnetic means. Since its creation, the telecommunications industry has developed further with new technology, such as the telephone, radio, television and computers. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems are excluded from the field. Modern telecommunications systems can transmit video, voice, graphic images and text information. The data traveling through a telecommunications system uses analog and digital electromagnetic signals.
