1. Information Capacity governed by Shannon's Formula
Shannon's Formula describes the amount of information that can be saved by a system of N states.

Information essentially is an interpretation of system's state. In general for any information system designed by humans, P(i) = P(j) = 1/n, so formula can be
S= - Summation(1:n) 1/n log b n
This will come out to be log b n where b is the base and in most cases b=2. So a system with just one state cannot store any information (log 2 1 = 0 ) and a system with two states can store log 2 2 = 1 or one bit of information.
