      Binary code works with base-2, which means that a binary digit, when on, will give you a value of 2^n, where n is the place you are in. For example, if you are working with a 4 bit chunk, 0000, the places represent 2^3, 2^2, 2^1, and 2^0 from right to left. Having a 1 in a place means that you add its value to the total. For example, 1011 is 8+2+1 or 11. Computers use these added up values to represent different things, such as in ASCII, where different numbers represent different characters. If you are wondering why we use 1s and 0s, it has to do with logic gates being only currently able of having an on or off position, with 1 being on and 0 being off.
