What this chapter is about In this chapter we discuss: Why computers use binary Logic gates Truth tables OCR Computing for GCSE © Hodder Education 2011

What you will learn Why computers use binary –What is meant by binary –The advantages of using binary numbers in computers instead of the denary numbers that we are used to OCR Computing for GCSE © Hodder Education 2011

What you will learn Logic gates and truth tables –What is meant by a logic gate –The three basic logic gates: AND, OR, NOT –How to draw logic circuits –How to work out the result of a logic circuit –How to summarise a logic circuit as a truth table OCR Computing for GCSE © Hodder Education 2011
