The Binary System

We are all familiar with the Denary number system based upon multiples of 10 – probably because we have 10 fingers to count on. The Denary system allows 10 individual digits which are 0 to 9. Any other number is built up using a combination of these ten individual digits.

Computers can only represent two numbers 0 (zero) and 1 (one). The number system based on just these two numbers is called Binary – which means two.

Each of the two digits in the binary number can represent any desirable numeric value.

Place values =

Binary =

Each 1 and 0 is multiplied by its own place value, and the results are added together:-

1 x 1 = 1

1 x 2 = 2

1 x 4 = 4

1 x 8 = 8

0 x 16 = 0

1 x 32 = 32

Total = 47

Binary only uses two digits, 1 and 0 and is often referred to as “base two”. Each place value can be seen as raised to the “power of” the position in the number.
