communications : the technology of the transmission of information (as by print or telecommunication) — Webster   See also OneLook


Communications, short for telecommunications, is the transmission of information over distances to communicate. In earlier times, it involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages such as coded drumbeats, lung-blown horns, and loud whistles. In modern times, telecommunications involves the use of electrical devices such as the telegraph, telephone, and teleprinter, as well as the use of radio and microwave communications, as well as fiber optics and their associated electronics, plus the use of the orbiting satellites and the Internet. — Wikipedia


Communications (Wolfram Alpha)


Communication, transportation and commerce have been intertwined since the beginning of human history, and they remain closely related.

The success of the first electronic telegraph line in 1844 opened an era of modern communication. Before the telegraph there existed no separation between transportation and communication. Information traveled only as fast as the messenger who carried it. — D. J. Czitrom, Media and the American Mind

This reality was even codified in the Dewey Decimal library classification system:

380 Commerce, Communications, Transportation (Library Thing)
