This is almost inevitable, since computers depend on streams of electronically generated ‘digits’ to function.so we have digital telephone lines, digital printing, digital radio and digital television, among the many areas connected with information, communication, and design. Virtually all data, whether it is the form of words, numbers, images, sound, or movement, can be digitized and transmitted using a range of technologies.
