Boolean operators and truth tables Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False.

This is why it’s important to understand and master these search operators. Why It’s Called Boolean. Boolean refers to George Boole, a 19th-century mathematician who invented Boolean logic.

Boolean logic - OCR Combining Boolean operators using AND, OR and NOT gates. At the simplest level, computers are little more than a collection of transistors and circuits.

Patterns of Boolean Logic Transistors (depicted here as mechanical switches) make up gates. Gates make up circuits, and circuits make up every digital device.

Boolean algebra is a branch of mathematics that deals with operations on logical values with binary variables. Boolean variables are represented as binary numbers to represent truths: 1 = true and ...

In Excel, Boolean logic (a fancy name for a simple condition that’s either true or false) is one way to sift specific data or results from a large spreadsheet. Granted, there are other ways to ...
