Overview

Boolean logic is the foundation of digital decision-making. It uses binary values, true and false, to represent and process information. George Boole developed this idea in the mid-19th century, and it became important in computer science, electronics, programming, and database queries. Logic gates

Key Concepts

Boolean logic is a type

Boolean logic is a type of algebra that deals with binary variables and binary operators. It uses only two values: true represented by 1 and false rep

A Boolean variable can take only

A Boolean variable can take only one of two values: true or false, yes or no, or 1 or 0. One bit represents one Boolean variable. In an electrical cir

A Boolean constant is a fixed
