Technology is the application of science through the use of tools.
Telecommunications systems Telecommunications systems transmit signals via cables, through the atmosphere, or through space. In so doing they support communication across distances. The distance over which telecommunications take place may be as small as the space between two workstations in the same room, or as large as the space between Voyager II and Florida. The medium The signal may be received on screen, through an audio device, on paper, or in combinations of two or all three of these. I identified decreasing cost, increasing versatility, increasing user friendliness, standardisation of formats and protocols, and the capacity for technologies to interact.
