A base-2 positional notation is a numeral system which only uses the digits 0 and 1. This is very well-known for machines understood it for its simple implementation. In fact, it is not only employed on computers but also on associated machines such as logic gates and facilitate internal communications among components of a machine.

Numeric value of a binary number depends on only two states which are usually designated as “on” and “off” (or in some cases, “yes” or “no”). Any number can be converted into binary numerals (bits).

Binary numbers read from right to left — digit by digit — to differentiate it from decimal numbers. Thus, the binary number “10″ is read as “one-zero” or its true value which is “two”. To clearly distinguish it from other numeral systems, binary numbers are noted as having an affix or subscript.
