boolean logic

Definition
Noun: A system of symbolic logic that uses algebraic rules to represent and manipulate logical statements, where all variables and results have only two possible values: true or false (often represented as 1 or 0). It is the foundational mathematical framework for digital circuit design and computer operations.
Usage
"Boolean logic" is an uncountable noun. It refers to the formal system itself. * Computer processors perform calculations based on boolean logic. * Understanding boolean logic is essential for programming. * The search engine uses boolean logic to filter results (e.g., using AND, OR, NOT).
Advanced Usage
- "To implement boolean logic": To physically realize logical operations in hardware (e.g., using transistors to create logic gates).
- The chip design implements boolean logic through a network of NAND gates.
- In a broader, metaphorical sense, it can describe any rigid, binary decision-making process.
- The policy was criticized for its simplistic, almost boolean logic, with no room for nuance.
Variants and Related Words
- Boolean (adjective): Of or relating to Boolean logic or its two-valued system.
- A boolean variable can only be
trueorfalse. - The boolean operator
ANDreturns true only if both inputs are true.
- Boolean algebra (noun): Often used synonymously with "Boolean logic," emphasizing its algebraic structure and rules.
- Logic gate (noun): A physical device that implements a basic Boolean function (e.g., AND, OR, NOT).
Synonyms

Related Phrases
- Boolean expression: A combination of variables and operators (AND, OR, NOT) that evaluates to true or false.
- The program's behavior is controlled by a complex boolean expression.
