Internet. Computer artwork representing the global communication made possible by the internet and electronic mail (e-mail). The image shows nine silver columns on top of which are differently coloured globes. In the foreground is a rainbow and in the background are rows of zeros and ones (binary digits). Computers use binary digits to communicate with each other because an electric pulse can be used to represent a "1", whilst no pulse registers a "0". Also in the background is a coloured grid. The Internet allows computers all over the world to send and receive images and text.
