Digital computers have circuits which representing data in terms of voltage levels. Multiple circuits are used to represent data (in the form of ''binary'' numbers).

Referring to the diagram on the right, the value of each decimal digit consists of the value (placeholder) multiplied by the corresponding power of 2. For example, '''2⁰''' , '''2¹''', '''2²''', etc. which move in a '''right-to-left''' direction.
