ENCYCLOPÆDIA BRITANNICA 

binary number system 

in mathematics, positional numeral system employing 2 as the base and requiring only two different symbols, 0 and 1. The importance of the binary system to information theory and computer technology derives mainly from the compact and reliable manner in which data can be represented in electromechanical devices with twox states--such z as "on-off," "open-closed," or "go-no go."
