Definition
- Noun:
- A logical operation: A
boolean operationis a fundamental operation in Boolean algebra and computer logic. It processes one or more input values, each of which must be either true or false (or, equivalently, 1 or 0, on or off), and produces a single output value that is also either true or false.
Usage
- A is a rule-based procedure applied to binary inputs.
- The term is used primarily in mathematics, computer science, digital circuit design, and programming.
- It describes the action of logical operators like AND, OR, NOT, XOR, NAND, and NOR.
Examples
- Noun:
- The
boolean operationAND returns true only if both of its inputs are true. - Designing a digital circuit requires a clear understanding of basic
boolean operations. - In programming, a conditional statement often relies on the result of a
boolean operation.
Advanced Usage
- "To perform a boolean operation": To execute a logical rule on binary data.
- The processor's arithmetic logic unit can perform millions of
boolean operationsper second.
Variants and Related Words
- Boolean algebra (n): A branch of algebra where variables represent truth values (true/false) and operations are logical.
- Boolean logic (n): The system of logical operations on binary variables.
- Operand (n): An input value upon which a is performed.
- Logic gate (n): A physical electronic device that implements a basic .
Synonyms
- Logical operation: An operation dealing with true/false values.
- Binary operation: An operation on two-state (binary) variables. (Note: In strict mathematical terms, a "binary operation" can have a broader meaning, but in computer contexts, it is often synonymous with ).
Related Phrases
- Truth table: A table showing all possible input combinations and the corresponding output of a .
- You can define a
boolean operationby writing out its complete truth table.
Noun
- an operation that follows the rules of Boolean algebra; each operand and the result take one of two values
