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 hundred’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

Two Units
