You are most likely using a computer with a 64-bit processor.

Sidebar: Understanding Binary The numbering system you first learned was Base 10 also known as Decimal. In Base 10 each column in the number represents a power of 10 with the exponent increasing in each column as you move to the left, as shown in the table:

Thousands Hundreds Tens Units 10 3 10 2 10 1 10 0

The rightmost column represents units or the values zero through nine. The next column from the left represents tens or the values teens, twenties, thirties, etc., followed by the hundredâ€™s column (one hundred, two hundred, etc.), then the thousands column (one thousand, two thousand) etc. Expanding the table above, you can write the number 3456 as follows: Thousands Hundreds Tens Units 10 3 10 2 10 1 10 0 3 4 5 6 3000 400 50 6

Computers use the Base 2 numbering system. Similar to Base 10, each column has a Base of 2 and has an increasing exponent value moving to the left as shown in the table below:

Two cubed Two
