George Boole was a philosopher and mathematician who lived from 1815 to 1864. He developed a system of logic operation of binary variables. This system is now known as Boolean logic and has been adopted as a model for counting in electronic computers.
In Boolean logic a variable can either be TRUE or FALSE. Processors consist of 'switches' that take on 2 positions that represent the same logic:
Either:
This occurs when a channel for electric current is open and the electric current flows through it.
This occurs when a channel for electric current is closed and there is absense of any flow of electric current through it.
