“Most computers have one or more conventions for representing numbers. One of the most common is the base 2 representation of numbers, in which the bit sequence 0000000 represents zero, the sequence 0000001 represents the number 1, the sequence 0000010 represents 2, and so on. The description of computers as “64-bit” or “32-bit” indicates the number of bit positions in the representation used by the computer’s circuits: a 32-bit computer uses a combination of thirty-two bits to represent a base-2 number.”
