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
A Boolean constant is a fixed value that can only be true or false, yes or no, or 1 or 0.
The main Boolean operators are
The main Boolean operators are AND, OR, and NOT. AND gives true only when both inputs are true. OR gives true when at least one input is true. NOT rev
Truth tables show all possible combinations
Truth tables show all possible combinations of input values and the output of a logical expression. The number of rows is calculated using 2^n, where
