Telephone communication. Conceptual image of the use of mobile telephones in global communication. The image shows 8 mobile telephones arranged in a circle and enclosed in a net (red). A circular grid is superimposed in the foreground. In the background are binary digits (1"s and "0"s), the language of computers and the vehicle for all digital communication of which the mobile phone is part. Also in the foreground are differently coloured, travelling globes, leaving a trail of binary digits behind them. Also in the background is the electronic circuitry that makes the mobile phone possible."
