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.

Boolean logic

What does a Boolean expression evaluate to?

Which of the following is an example of a Boolean statement?

Which logic gate has only one input and one output?

What is the output of an AND gate when both inputs are 1?

How many possible input combinations exist for an AND gate with two inputs?

What is the result of the statement "NOT raining" when it is raining?

What do binary digits represent in hardware logic?

A Boolean logic system in computers processes data using 1s and 0s, which represent high and {{}} voltages.

Logic gates are physical components used in computers to carry out {{}} operations.
