ITIC:Digital representation - Binary
A computer stores data in "digital" format, meaning that it stores information as numerical representation, using what is called "binary" numbers.
A Binary number is a number which can be represented using only two symbols (normally 0 and 1). One such binary digit (a 1 or a 0) is called a "bit" (which is actually short for BInary-digiT).
Using only 0 and 1, we can represent two values in one such bit. The decimal numbers we can represent using only one bit are also 010 and 110.
