an expression that evaluates to either True or False

an electronic component that carries out a logical operation

a table showing the outputs for all possible combinations of inputs to a logic gate

Boolean logic and logic gates

In this unit pupils will discover that Boolean logic is a way of describing circuits inside a computer. They will recognise logic gates as the building blocks of processors. They will be able to construct logic diagrams, truth tables and simplify Boolean expressions.
