It is argued that a randomly fabricated electric circuit functions as an information processor. Indeed, the neuronal system of Caenorhabdilis elegans (C. elegans) is a random network which processes various information for the survival of the worm. After properties of the connectivity of the neuronal system of the worm are reviewed to emphasize its randomness, it is confirmed that a network of resistors, which is topologically homologous to the neuronal network of C. elegans, can encode a decision table which is similar to the decision table of the native responses of the worm. Some structural properties, which are advantageous for the functioning of a random resistor network for an information processor, are discussed. In addition, it is suggested that a network of resistors with these propeties is a bundle of intertwisted wires connected by some resistive particles.
