Binary Numbers

Binary numbers are a sequence of four numbers, like 1001 or 1010. Each of the four represent the number 8421. For example the number 1001 represents 9, because there are numbers 1 in the 8 and 1 section. Binary numbers are four-bite byte numbers with all the "switches" set to "on", where "on" is represented by 1. The "off" stare for a switch would be shown as a "0".
