Some stuff to add:
A bit is a short form of "binary digit". It can either equal 1 or 0. It is the ultimate "core" of how computer processes data.
32-bit processor: 2^32 = 4,294,967,296
This means that you computer can represent numbers from 0 to 4,294,967,295 in binary.
64-bit processor: 2^64 = 18,446,744,073,709,551,616
That can represent A LOT more numbers in binary, therefore making the data processing much faster. That's pretty much the main difference.
