Card 1Binary Logic System

What is Boolean logic?

Answer

Boolean logic is a type of algebra that deals with binary variables and binary operators. It uses two values: true and false, or 1 and 0. It is widely used in computer science, electronics, and databa…

Card 2Binary Logic System

Who developed Boolean logic?

Answer

Boolean logic was developed by George Boole in the mid-19th century. He showed how formal logic could be written in mathematical form.

Card 3Binary Logic System

What are the two possible values in Boolean logic?

Answer

The two possible values are true and false, written as 1 and 0. A binary decision always results in yes/no or true/false.

Card 4Binary Logic System

What is a Boolean variable?

Answer

A Boolean variable is a type of variable that can take only one binary-valued quantity from two possible values such as yes/no, 1/0, or true/false. One bit represents one Boolean variable.

Card 5Binary Logic System

What is a Boolean constant?

Answer

A Boolean constant is a fixed value in a program that can take only one of two values: true or false, yes/no, or 1/0. It is different from a Boolean variable because it does not change.

Card 6Binary Logic System

What does a passing signal represent in an electrical circuit?

Answer

In an electrical circuit, a passing signal represents 1. If the signal does not pass, it is represented as 0.

Card 7Boolean Operators

What is the AND operator?

Answer

The AND operator returns true if and only if both operands are true. In logical multiplication, its symbol is the dot operator (. ).

Card 8Boolean Operators

What is the OR operator?

Answer

The OR operator returns true if at least one operand is true. In logical addition, its symbol is the plus operator (+).
