Basic Rules Switching algebra is easily visualized using switches since there are only two values: on and off, or true and false. In digital systems we represent these as 1 and 0, respectively.

Boolean algebra makes it possible to use the same kinds of algebraic techniques we use to solve normal equations involving numbers to establish logical relationships.

And now, Boolean logic is ingrained in almost every computer language. When you use a modern search engine, Boolean logic is used to filter the results to show you only the words you included in ...

But it's Boolean logic, or Boolean algebra, for which he's known today. The concept goes far beyond the and and or operators most of us have learned to use in the "advanced" options of search engines.

Algebraic Immunity: A metric indicating a Boolean function’s resistance to algebraic attacks, reflecting the minimum degree of an annihilator function that can simplify its structure.
