The Challenge of Long-Distance Communication

Communication involves the sharing of ideas, information, sounds, or images. Communicating over distance requires three stages: encoding, transmitting, and decoding. For instance, about 1,500 years ago, the Incas—a highly organized, methodical culture without any written language—used quipus to communicate numeric information. A quipu was a method of encoding numbers for record keeping, and it involved an intricate set of knots tied into colored cotton cords that were connected in specific ways. The knots represented numbers stored in base-10, with the absence of a knot indicating zero, so that the user could distinguish, for example, between 48 and 408. Runners transmitted the information by carrying the quipu from one location to another. Whoever needed to look up the record, studied the knots and decoded the information.

Methods of encoding, transmitting, and decoding have advanced with technology. We now can encode and decode with...
