   An easy method of converting a decimal number into a binary number is by dividing the decimal number by 2 progressively, until the quotient of zero is obtained, The binary number is obtained by taking the remainder after each division in the reverse order. This method is popularly known as the double-double method.

       The Binary number system is simple because it consist of only two digits, there is 0 and 1. Just at the decimal system with its ten digits is a base-ten system, the binary system with its two digits is a base-two system. the position of 0 or 1 in a binary number indicates its "weight" within the number. In a binary number, the weight of each successively higher position to the left is an increasing power of two.
