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

A truth table is a table showing the outputs for all possible combinations of the {{}} to a logic gate or logic circuit.

What is the output of the Boolean expression NOT (True AND False)?

Which Boolean expression represents the following scenario: "I will go to the park if it is sunny OR it is NOT raining."

What is the output of the Boolean expression (True AND False) OR True?

A truth table with three inputs will have how many rows?

In a truth table for the expression A AND (B OR C), which columns would you include?

What is the order of precedence for Boolean operators?

Which logic gate outputs True only when both inputs are True?

represent a logical expression as letters.

identify why a circuit isn't working and debug it.

A logic circuit uses two or more {{}} components to implement a more complex logical statement.

Identify the input or inputs for this sentence: "I will go to the park if my friend is not busy, and it is sunny".

Identify and label the inputs and the outcome.

Put the steps to write a logic statement in order.
