code: Translating from one system of values to another system.
Electricity
The Binary System: a system where the only two numbers available are 0 and 1. Every operation that we can do in decimal, with 10 digits, we can also do in binary.
The Transistor: A switch controlled by electricity.
Two giants for computer science:
George Boole (1779-1848): logic expression = boolean expression. Logic: creating formulas where variables are combined by operators. The variables are boolean variables, the operators are logic operators. Any formula can be represented with a combination of just three operators: AND, OR, and NOT.
Claude Shannon (1916-2001): writes a Master's thesis at MIT in 1948, which states that any binary numerical computation can be performed using logic expressions and logic operators.

You will find Wikipedia's description of the processor interesting. Concentrate mostly on the sections labeled Microprocessor, Operation, and Clock Rate.
