Booleano

Booleano is the Italian term for boolean, referring to the concept of truth values in logic and computing. It derives from the work of George Boole, whose algebraic treatment of logical expressions laid the foundation for modern logic and computer science.

Boolean algebra uses two truth values, true and false, and operations such as AND, OR, and NOT. The subject also includes XOR, implications, and equivalences. Truth tables summarize how each operation combines input values, and De Morgan's laws describe the relationship between negation and conjunction/disjunction. These ideas underpin digital circuits and many programming constructs.

In programming, a booleano indicates a data type that holds truth values and controls flow through conditional statements and loops. Languages provide boolean literals like true and false; some systems map booleans to integers (1 and 0). In user interfaces and data formats, Italian terms for true/false include vero and falso, and in some contexts booleans are represented by 1/0.

Applications include search filters, flags, configuration options, and database predicates, where boolean expressions determine which records to select or which code paths to execute. Boolean logic is also used in formal verification and algorithm design.

Historically, the term comes from George Boole (1815–1864). The formalization of boolean algebra was extended by logicians such as Charles Peirce and Ernst Schröder and became central to the development of digital electronics in the 20th century.
