A bit is a 0 or a 1. Two bits is 00, 01, 10, or 11. Each bit doubles the amount of information. This means that information representing information as bits products powers of 2. To get the number of bits (the power of 2 to represent the number), one takes the log, base 2, of the number. If I took the example of 2 bits and limited it to 00, 01, 10, there would be 1.6 bits. Log2(3) = 1.6.
